Temporary irradiation facility at the CNGS beam D. Mcfarlane, T. Wijnands,
Motivation to test equipment on site Exposure to LHC like radiation field Short turn around Pre selection of components facilitated Complete systems tests (crates) before installation RP issues
MC simulations ARC per Gy –1 x 10 8 to 1 x n > 100 keV –2 x 10 8 to 4 x 10 9 n > 20 MeV –2 x 10 8 to 2 x 10 9 n > 100 MeV CNGS per Gy –1 x n > 100 keV –5 x 10 9 n > 20 MeV Dose rates : CNGS : 1 to 150 Gy per week ARC-DS : 1 to 200 Gy per year
