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….
