Technical Specifications Facility
Radiation field Irradiation source: 137Cs of 7 – 10 TBq, front and rear
irradiation field (Talk by R. Fortin) Particle beam: 100 GeV muons, 104 muons per spill in 10 x
10 cm2
Area layout Bunker (enough space for detectors 3 m wide and 4 m high) Detector preparation area Short term storage area Control room/barracks
Control and logging system Hard-wired common control system (source, beam, gas) Web based monitoring and logging

be discussed] Temperature controlled environment (20° C, 30-50% humidity) Trigger setup Dose rate monitoring Beam instrumentation
Neutral gases: Ar, N2, CO2, He, Xe at > 5 barFlammable gases: iC4H10, CH4, Ar/H2
Special gases: C2H2F4, SF6, CF4
Mixers, consumption monitors, analysis

GIF++ Use Case
29.06.2012Dorothea Pfeiffer
Arrival of detector through door on
Salève side
Lift detector with crane into
short time storage/waiting
area
Move detector to preparation
area
Validation tests of detector in
preparation area
Connect gas lines, power and control cables,
DAQ
Move detector into bunker
through sliding door
Mount detector on scanning
system
Start long term irradiation test
Control and monitor from control room (unattended mode also possible)

Infrastructure Issues
Access system: Single Person Access System (SAS) is required due to source activity
Temperature and humidity control of bunker: required values, admissible fluctuations, implementation (tent)?
Space for racks in bunker really needed? Scanning device needed? How to implement it?
Others will come as we advance with the detailed design of the facility….
