Facility Design Targets • Contrary to other facilities: • Setup needs to be radtol • Large distance: ≈ 30 m of cables. Designer needs to integrate in their design the possibility to measure short signal (e.g. short transient “few ns”) and also to work at high speed. • But … • Numerous representative radiation fields • Mixed-Particle-Energy • Direct beam exposure • Large range of fluxes and dose ranges(covering accelerator, but also other applications)
Facility Design Targets • Possibility for large volumes/high number of components or full systems • Easy usage • Dedicated preparation area • Cables pre-installed + patch panel • Conveyer systems • Detailed, on-line andhigh-accuracy monitoring (CERN RadMon system)
Conclusions • Contract with Fraunhofer (TID/DD) optimized • PSI contract (to be adjusted after 2015) • Critical collaborations with other institutes (help and support) • External companies → To be taken with care (standards components → OK complex systems → To be checked) • Costs are mainly covered by R2E project (whenever operation impact) • Campaigns are coordinated (optimized) through RadWG • Strong collaboration with all the users/groups
Conclusions • Testing complex systems or many components can be important/useful • BI request → First planning ? • Because: • Huge amount of tests in the coming years • CNRAD activity stopped • H4IRRAD activity limited • PSI not available mid-2014/2015 (at least for 4 months) • A new test facility will soon be available at CERN (mid-2014) • In view of the amount of test requirements at CHARM →Need of an efficient coordination/operation
