SPSC Recommendations (p.62)

● ν physics has noble history at CERN

● ν physics is in a new golden era - CERN beginning again pivotal global role

● CNGS commitment to ~ end of decade vital - 2006 important: COMPASS then CNGS @ end 06 - CNGS crucial up to 2011 (window @ 4.5x1019pot/yr) - CNGS + COMPASS ? multi-turn xtraction

longer running period - no compelling case for extending CNGS beyond 2011 @ realisable pot/yr (< ~ 3x 4.5x1019pot/yr)

R.G. 5 17/03/2005

● Future neutrino facilities offer great promise for fundamental discoveries (such as CP violation) in neutrino physics, and a post-LHC construction window may exist for a facility to be sited at CERN.

● CERN should arrange a budget and personnel to enhance its participation in further developing the physics case and the technologies necessary for the realization of such facilities. This would allow CERN to play a significant role in such projects wherever they are sited.

● A high-power proton driver is a main building block of future projects, and is therefore required.

● A direct superbeam from a 2.2 GeV SPL does not appear to be the most attractive option for a future CERN neutrino experiment as it does not produce a significant advance on T2K.

● We welcome the effort, partly funded by the EU, concerned with the conceptual design of a β-beam. At the same time CERN should support the European neutrino factory initiative in its conceptual design.

Implications of SPSC Villars’s recommendations for the AB department are being sent to the Research Board

Special INTC meeting (Villars – Oct. 2005) new set of recommendations Creation of an accelerator team to elaborate scenarios Accelerator studies in the frame of:

CARE [EU supported Integrated Activity: “Coordinated Accelerator Research in Europe” including networks (BENE: “Beams for European Neutrino Experiments”, H3: “High energy, High intensity, High brightness” accelerators) and the Joint Research Activity HIPPI: “High Intensity Pulsed Proton Injectors”]

LHC upgrade studies EURISOL Design Study [EU supported]

R.G. 9 17/03/2005

Personal comments

In the short/medium term (~ 2010): shortage of proton beams for the approved users (worse if their expected upgrades are taken into account…) and risk with beam loss / hardware activation Need for: implementing improvements as soon as possible arbitration between users…

In the long term = Future of proton accelerators at CERN

LHC will operate until ~ 2020

Consolidation + LHC upgrade

LHC will always be a part-time user of the injector complex

Other physics programmes can be covered if they are compatible with LHC needs. On top of value for science, synergy will be an important parameter.

PROGRESS OF LINAC DEVELOPMENTS

R.G. 11 17/03/2005

Three stages are planned:

Stage 1: 3 MeV test place development and test of linac

equipment, beam characterization

Stage 2: Linac4 New linac replacing the

present injector of the PS Booster (Linac2)

Front-end of the future SPL

improvement of the beams for physics (higher performance and easier operation for LHC, ISOLDE etc.)

Stage 3: SPL New injector for the PS, replacing the PS Booster New physics experiments using a high proton flux

improvement of the beams for physics and possibility of new experiments

Stage 1: 3 MeV test place

R.G. 13 17/03/2005

REQUEST1. COST ESTIMATE FOR THE 3 MEV TEST PLACE

The preparation of a realistic cost estimate has started in September 2004. After a few iterations to minimize the expenses (e.g. a single klystron will be installed because the RF tests of the accelerating structures for Linac4 will take place in SM18) and to spread them evenly over the years, the outcome is now available (see annexed table). This analysis assumes that the klystron power supply is delivered “free of charge” by India and the third buncher by China.

The resulting figures (kCHF) are summarized in the following table:

o the “Expenses” are the estimated amounts needed. It does not take into account the carry-over from 2004 to 2005 which is unknown today (estimate on January 27: ~ 280 kCHF).

o the “Allocated budget” is what is presently foreseen for the linac developments.

o the “Difference” is the missing amount.

Considering that the present estimate is still an approximation, an additional amount of 400 kCHF per year is requested to allow completing the 3 MeV test for the end of 2007. This will bring the budget for linac developments at the level of 800 kCHF/year during the years 2005-2007. This includes means to pursue with other developments for Linac4 in the course of 2007

Main outcome

All talks are on EDMS (document number 554659 ) Planning is tight. Feasible but no margin for drift. Apart from the RFQ, construction of equipment and installation of

the test place in Saclay are progressing satisfyingly. On the CERN side, preparation of hardware is advancing,

although with delay due to priority of LHC in the workshop. Great hopes on the solid-state chopper driver and BSHM.

RFQ construction is on the critical path. CERN brazing workshop will have to braze all sections within 9 months ! First section to be brazed in the middle of March.

Vacuum testing of the existing RFQ section shows weaknesses. Will be repeated in a joint effort bewteen CERN & IN2P3 specialists. Crucial for deciding upon its acceptance at CERN…

Next meeting will be organized by IPNO in September/October. Main item will be the progress with RFQ construction.

CERN DG’s talk to the staff on 10/01/2005 (1)

The following strategic orientations are proposed for CERN activities in 2004-2010:

1. to keep the utmost priority for the completion of the LHC project, and strive for a start of operations in the summer of 2007;

2. to fulfil commitments previously made by CERN: CNGS, EGEE;

3. after an in-depth risk analysis review, to mitigate the consequences of failure of old equipment that is necessary for reliable LHC operation. i.e. Consolidation;

4. along the conclusions of SPSC Villars meeting, to prepare for 2006 and beyond a few new fixed target experiments, highly praised for their new physics potential outputs;

5. in line with the new policy by the European Commission for structuring the European Research Area, by promoting the coordination of laboratories in matters of R&D and new infrastructure (FP6 – CARE programme), to launch in the period 2004-2006 different studies in cooperation with other laboratories;

R.G. 30 17/03/2005

Their primary goal would be:

to develop detailed technical solutions for a future LHC luminosity upgrade to be commissioned around 2012-2015;

Definition of the Linac4 (160 MeV-H-), in relation with the European Programme for a High Intensity Pulsed Proton Injector (HIPPI)

Definition of modifications to the magnets in the interaction regions at two crossing points of the LHC beams, linked with the European programme Next European Dipole (NED), aiming at 15 Tesla

Definition of new trackers for the upgrade of the ATLAS and CMS detectors, to withstand a factor 10 higher luminosity.

to keep in touch with other design studies launched in Europe, of EURISOL and neutrino factories;


R.G. 31 17/03/2005

Milestones …

7. in 2006-2007, to decide on the implementation of the Linac 4 and any increased R&D programme, depending on new funds made available and on a new HR policy;

8. in 2009-2010, to review and redefine the strategy for CERN activities in the next decade 2011-2020 in the light of the first results from LHC and of progress and results from the previous actions. The possible choices are at present quite open. The future role of CERN will depend on these choices and their effective funding;
