1. INTRODUCTION
The proton irradiation facility in the PS East Area (known as IRRAD1), on the T7 beam line, was
heavily and successfully exploited for irradiation of particle detector elements, electronic components
and detector materials since 1992. The mixed-field irradiation facility (known as IRRAD2) was
instead implemented behind the DIRAC experiment on the T8 beam line and has been operated
parasitically to DIRAC since 1998 [2]. These facilities received particle bursts - protons with
momentum of 24GeV/c - delivered from the PS accelerator in “spills” of about 400ms (slow
extraction). In IRRAD1, the proton beam was spread out in order to produce a uniform irradiation spot
of several square centimetres, while in IRRAD2 the irradiation was performed in a small cavity with
secondary particles produced by the primary proton beam impinging on a thick target made of carbon,
iron and lead [3]. In the past 15 years, more than 8300 “pieces” were irradiated using this
infrastructure.
Based on previous studies carried out during the years 2007-2010 [4], the need of improved irradiation
facilities at CERN, was confirmed and consolidated. More specifically, in view of the high-luminosity
upgrade of the LHC and its experiments, the old PS East Area (EA) facilities suffered from a number
of restrictions:
1. the available space was very limited and allowed only the irradiation of relatively small and
stand-alone objects;
2. the proton flux was limited on the one hand by the weakness of the shielding and, on the other
hand, by the competition for proton spills with DIRAC;
3. the access to the IRRAD1 proton facility required long cool-down time and a stop of the
operation in the whole EA for the full duration of the access.
In the framework of the AIDA project, an upgrade of the all EA irradiation facilities on the T8 beam-
line was proposed based on the assumption that DIRAC would have concluded its experimental
program in 2012. The DIRAC experimental apparatus was then decommissioned during 2013 and in
the following the new EA-IRRAD facility was constructed and is today being commissioned at its
place in the framework of the overall renovation project of the PS East Area [5]. The EA-IRRAD
project involves several CERN groups belonging mainly to the Engineering and Physics department.

Figure 1: Layout of the PS East Area until 2012 (left). New combined EA-IRRAD facility implemented on the
T8 beam-line (right): the proton area, IRRAD (upstream), is followed by the mixed-field area CHARM
(downstream).
As shown in Figure 1 (right), the new proton irradiation facility (named IRRAD) has been constructed
at the location previously occupied by the DIRAC target [1,6]. A photo of the facilities is given in
Figure 2. While the mixed-field facility (named CHARM [7]) is constructed downstream of IRRAD, in
the location where the former DIRAC detector was installed (left of Figure 1). This solution has
several advantages:
1. the access to the facility is independent of other experiments located in the PS EA;
2. the layout is optimised for exploitation as an irradiation facility, with appropriate shielding,
ventilation, dedicated infrastructure and sufficient space for a proper installation and easy
accessibility of the equipment;
3. the same protons are used for both IRRAD and CHARM, thus leading to a strongly improved
PS cycle economy and optimal use of available protons.
In the new IRRAD facility, a particle fluence of about 1×1016 p/cm2 could be reached in 5 days over a
surface of 12×12mm2 (FWHM). This roughly corresponds to a factor 4-increased intensity with
respect to the previous IRRAD1 facility. In the following of this paper, the key characteristics of the
new IRRAD facility as well as the first commissioning of the facility and its infrastructure will be
described in more detail.

2. LAYOUT OF THE IRRAD PROTON FACILITY
The IRRAD bunker is subdivided in three zones according to the nature of the samples to be
irradiated. With reference to Figure 3 (from upstream to downstream), the first zone is dedicated to the
irradiation of “light” materials such as small silicon detectors, the second zone to the irradiation of
intermediate materials such as electronic cards and components, while the third zone is optimized to
perform irradiation experiments on “high-Z” materials such as samples of calorimeter crystals. In this
last zone, it will be also possible to perform irradiations in cryogenic conditions using a dedicated
setup operating with liquid Helium. Moreover, a fourth zone, in a partially shielded area, is equipped
for the installation of readout electronics and/or DAQ systems that need to be close to the Devices
Under Test (DUT) during irradiation.
Figure 3: Detailed layout of the IRRAD proton facility.
In between each irradiation zone, an 80cm-thick concrete separation wall is installed in order to reduce
the background during operation and to minimize the ambient dose equivalent to the personnel
accessing the area. As visible in Figure 3, in order to reduce further the secondary radiation produced
by the interaction of the proton beam with the air, sections of vacuum beam-pipe are installed in the
empty space between the various irradiation systems. A more detailed description of the overall
facility is given in reference [1]. In the following we concentrate on the equipment of the facility that
was produced in the framework of the AIDA project and its commissioning in the period of October to
December 2014.
The DUTs are installed and positioned in the proton beam by using two different types of remote
controlled holders: the irradiation tables (see section 3.1) partly equipped with cold boxes (see section
3.2) and the irradiation shuttle (see section 3.3). A set of beam instruments has been installed inside
the IRRAD bunker to allow a constant monitoring of the irradiation conditions (see section 3.4).
Finally, a new offline fluence monitoring system has been developed and commissioned (see section
3.5). In section 4 a brief report about the first commissioning run of the facility and its infrastructure is
given.

3. FACILITY INFRASTRUCTURE
3.1. IRRADIATION TABLES
The tables are remote-controlled stages providing the possibility to position the DUT with ±0.1mm
precision in the transversal plane (X-Y) with respect to the beam axis. The tables also rotate over the
azimuthal angle () in order to achieve a precise alignment with the beam within ±0.025º. The
prototype of an irradiation table is shown in Figure 4. The installation of the samples on the table
requires the access to the proton area.
Three independent groups of tables will be installed in the three zones of the IRRAD facility bunker. A
maximum of three tables per group (e.g. 9 in the whole facility) can be installed and operated. This
allows the irradiation of several materials at the same time with a “clean” proton beam and minimum
background induced by scattered secondary particles.
On each table, the maximum volume available for irradiation is of 200×200×500mm3 while the
maximum samples weight is 50kg. The tables can automatically move (e.g. “scan”) the samples during
irradiation in order to provide a uniform spot over the 200×200mm2 surface (or a smaller portion of it,
depending on user request). On these tables, the test of equipment “in operation” (e.g. powered and
connected to a DAQ system) is possible as well as irradiation of detector components at low
temperature, down to about -20ºC, using specially designed irradiation boxes with temperature control
(see Figure 4 and section 3.2). A more detailed description of the tables can be found in the milestone
report MS31 [8].
Figure 4: Prototype of a table for proton irradiation equipped with a prototype thermalized irradiation box
for device cooling during irradiation.
3.2. COLD BOXES
In order to provide realistic operational conditions during the irradiation experiments, some samples
have to be kept at low temperatures. Silicon based detectors in the LHC experiments are for example
kept cold in order to avoid annealing effects, reduce the leakage current and avoid thermal runaway of
sensors and electronics. A typical anticipated temperature is -20°C. In the irradiation facilities part of
the experiments will thus have to be performed in cold boxes assuring a stable and low temperature
during irradiation. Figure 4 shows a prototype cold box mounted on a 2-axis movable table. The
University of Sheffield has designed (see Figure 5 ) and produced (see Figure 6) a series of cold boxes
for such experiments.

Figure 5: Technical drawing of the cold box.
Figure 6: Cold boxes delivered to CERN.
The boxes have been operated successfully at the irradiation facility in Birmingham [9-11] (see Figure
7). The first test of the prototypes under load while cooled to -25°C demonstrated a weakness in the
circulation of the coolant. Therefore, a new radiator was designed and manufactured in Sheffield with
larger bore cores and larger cooling fins to improve thermal conductivity (see Figure 8). Testing was
then completed using the Birmingham Irradiation Facility, and showed a 50% reduction in cool down
time of the thermal box and a reduced load on the chiller pump (8.4 bar compared to 2.2 bar).
Cold boxes with this new radiator type have been delivered to CERN in the end of 2014 and are fully
operational. Due to lack of beam time, they could not yet be tested in situ and will be commissioned
with beam in the first irradiation run in 2015. No complications are expected as they have been
commissioned with beam in the Birmingham facility already.

3.3. IRRADIATION SHUTTLE
The shuttle is a remote-controlled trolley travelling on a rail system and allowing the positioning of
“small” objects in the beam (typically silicon detector test-samples) without the need of human access
into the area. This system guarantees a precise X-Y alignment of ±0.1mm with respect to the beam
axis and it is mainly designed for the irradiation of passive samples at RT. The shuttle for the new
proton irradiation facility is cloned from the previous IRRAD1 and IRRAD2 shuttle systems and
shown in Figure 9. The shuttle (see Figure 10) travels across the shielding blocks for a length of about
10m inside a conduit of 400×400mm2. To minimize the direct radiation streaming, the path of the
conduit follows a chicane located in between the first and the second group of irradiation tables (see
Figure 3). On the shuttle, the maximum volume available for irradiation is of about 50×50×200mm3
for a maximum weight of about 1Kg. The standard size of the beam spot on the shuttle system () is of
about 5-7mm RMS but it can vary according to the different beam focusing options. In particular,
focusing on the shuttle system, the spot size can be reduced further down during high-intensity
irradiation periods. Two radiation monitors (Automess 6150AD6) are installed on the shuttle and are
used to measure remotely the radiation levels of the irradiated samples while being removed from the
irradiation area.

The shuttle system shown in Figure 9 has been installed in the irradiation facility and is now deeply
embedded in the facility shielding leaving only access to the irradiation and loading position of the
shuttle. The end of the shuttle conduit inside the new irradiation facility is visible in Figure 11. It is
labelled “SHUTTLE IRRAD-1”. The shuttle itself arrives to the beam position behind the Kapton
window covering the opening in the conduit.

guiding the beam into the irradiation area. In the middle a table system is located with the possibility to
mount 3 remote controlled irradiation tables. Only one position labelled IRRAD-7 is occupied with a table.
Against the wall in the back the end of the shuttle conduit can be seen labelled with IRRAD-1.
During the commissioning run in 2014 the shuttle system was not operated due to time constraints.
The shuttle will however be used in the first irradiation runs in 2015.

3.4. MONITORING THE BEAM CONDITIONS
The intensity of the extracted proton spills is monitored using a Secondary Emission Chamber (SEC)
device provided by PS beam instrumentation. This device is installed in the upstream machine area,
and its signal is made available in the counting room together with the other signals provided by the
PS timing-distribution. The profile of the proton beam with a spill-by-spill resolution is obtained by a
custom-made Beam Profile Monitor (BPM). The operation of this instrument is based on the
secondary electrons emission effect. One BPM is located upstream the IRRAD area, in the same
location as used for the SEC. An example display of one proton spill as taken during the
commissioning of the facility in October 2014 in shown in Figure 12. Additional BPM devices will be
distributed among the 3 irradiation zones, along the trajectory of the proton beam, to guarantee the fine
tuning of the beam profile on all irradiation systems. The absolute calibration of this beam
instrumentation in terms of p/cm2 is obtained by means of activation measurements of thin aluminium
foils which will be in the future complemented by the AIDA fluence monitoring system described in
section 3.5.
Figure 12: Beam profile taken with the beam profile monitor during the commissioning run in October
2014. Every individual spill of protons is monitored and recorded with its beam shape and intensity.
3.5. OFFLINE FLUENCE MONITORING
The VUTEG-5-AIDA fluence monitoring system is based on the direct relation between carrier
recombination lifetime in Silicon (Si) and density of radiation induced extended defects. The carrier
recombination lifetime is strongly degrading with the irradiation fluence [12-14]. A measurement of
the carrier lifetime in Si can thus be used to determine the particle fluence, the Si has been exposed to.
The measurements are performed in a contactless manner on pure Si wafer fragments using a
microwave absorption technique. The surfaces of the Si wafers are passivated (e.g. with thermal oxide)
to extend the dynamic diapason of controlled lifetime values towards the range of small fluences.
A first version of the instrument that was designed and fabricated at the Vilnius University, and was
successfully tested at the old CERN IRRAD facility in November 2012. The carrier lifetime
dependence on irradiation fluence was calibrated for Silicon material sets of different growth
technology and conductivity type. Example measurements are given in Figure 13. The dependence of
the carrier trapping lifetime, attributed to point radiation defects, on annealing temperature and
exposure time was also revealed and examined as depicted in the figure.

conduction type (n-type and p-type). After irradiation and the first measurement (“as-irradiated”) the
annealing of the recombination lifetime at an elevated temperature of 80°C was studied.
During the last stage of the project implementation in the year 2014 the contactless dosimeter has been
developed into a more sophisticated multi-purpose instrument (VUTEG-5-AIDA). The software of the
measurement control and data processing has been upgraded. A computer controlled 1D stage has
been implemented for single line scans of lifetime distribution within irradiated Si wafer fragments.
This last version of the instrument enables a rapid evaluation of the contour of a particle beam and its
homogeneity by a computer controlled positioning which can be made with precision of 2 m.
Additionally, a lateral scan can be implemented by manual shift of the sample mounted within a
spring-supported sample holder with precision of about 500 m. The irradiation fluence is evaluated
according to previously taken calibration curves using the absolute values of carrier lifetime. The
comprehensive sample chamber has been tested for irradiation beam profiling. All the measurement
procedures, after mounting of the sample under test, are computer controlled. The re-arranged
contactless dosimeter VUTEG-5-AIDA is thereby supplied by two sample chambers: one of them has
been improved and devoted for rapid monitoring of Si samples of dimensions of about 1010 mm2
placed in plastic bags for dosimetry, and another for research of particle beam parameters and for
scientific characterization of the irradiated samples and e.g. their annealing properties. Pictures of the
VUTEG-5-AIDA dosimeter are illustrated in Figure 14 and Figure 15.

The tests of lifetime values dependent on neutron irradiation fluence have complementarily been
performed using MCZ Si wafer fragments. The instrument has also been tested using Si wafer
fragment irradiated with protons at the IRRAD facility. The mapped profile of the carrier
recombination lifetime single-dimensional distribution is illustrated in Figure 16 below, where rather
sharp proton beam of diameter 5 mm contour is reproduced.

written to also allow un-experienced users after a short introduction to perform measurements.

4. COMMISSIONING OF THE FACILITY
The commissioning of the CERN IRRAD facility started on Friday October 10th 2014 at 21:13 when
for the first time the primary 24 GeV/c proton beam extracted from the PS went through the new East
Area Irradiation Facility. The first weeks of operation, using a low intensity proton beam, are mainly
devoted to the beam steering and commissioning in order to study several T8 beamline optics
configurations required for the parallel operation of IRRAD and CHARM. Moreover, this pilot beam
was also used to test and calibrate the T8 beam instrumentation. This includes Secondary Emission
and Ionization chambers, a MWPC device and the IRRAD Beam Profile Monitors (BPM) that are
installed along the beam trajectory in the IRRAD area. The IRRAD BPMs are pixelated metal-foil
detectors based on the secondary electrons emission effect. A typical profile of the irradiation beam,
taken with a BPM during the first days of operation, is shown in Figure 12. Four BPMs are installed in
the IRRAD area allowing a precise and real-time tagging of the proton beam shape/intensity in the

irradiation positions acting as a key element for the tuning of the proton irradiation beam. The
commissioning was performed together with the secondary beam-line physicist and the BE-OP
operator crew which controls the irradiation beam from the CCC. In parallel to this commissioning the
fluence monitoring system, produced at the Vilnius University, and the cold boxes, produced at the
Sheffield University, reached CERN and were tested and prepared for operation.
In November/December 2014 first irradiations for facility users were performed. Due to the limited
number of irradiation days and positions on the installed irradiation tables only a fraction of the
requested irradiations could be performed. The remaining requests had to be postponed to the next
irradiation period expected to start in May 2015. A total of 177 samples organized in 82 SETs (groups
of similar samples irradiated to same fluence) were irradiated to different fluences as requested by the
users. The table below (Table 1) gives an overview of the users community and the irradiated objects
for this first commissioning run of the facility and the Figures show some of the samples during
irradiation (Figure 18, Figure 19, Figure 20).

5. CONCLUSION
The new IRRAD facility has been successfully commissioned from October to December 2014. The
AIDA equipment deliverables in form of remote controlled tables, cold boxes, an offline fluence
monitoring system and the shuttle system are operational and working to expectations. Only the shuttle
system and the cold boxes could, although operational, not be tested in situ during the commissioning
run in 2014. They will be commissioned with beam during the next irradiation period expected to start
in May 2015.
The deliverable D8.10 “Commissioning of new facility equipment” has thus been realized as
documented in this report.
