1 Proton and neutron radiation facilities in the PS East hall at CERN Maurice Glaser, Michael Moll, Federico Ravotti CERN Division PH-TA1-SD

2 PH-TA1-SD meeting Irradiation, Storage, Expedition…..in Hours of proton irradiation (83 Days) (85 04) 2424 Hours of neutron irradiation (101 Days) (60 04) 579 Samples irradiated and traced 377 Dosimetry with Ge spectrometer 202 Dosimetry with NaI spectrometer 65Users from 30 institutes 55Expeditions all over the world o C) 30 Dosimetry with Si detector 5 Different places for storage (Low T < -20ºC)

3 PH-TA1-SD meeting Samples irradiated

4 PH-TA1-SD meeting Dosimetry and beam profiling Gafchromic dosimetric Films: We characterized different types for dose measurement and beam profiling. MD-55HD-810 XR - Type HIGH SENSITIVITY MEASUREMENTS XR Film exposure of the beam after a few bunches of 42 ns. 6cm VERY USEFUL FOR SPECIAL IRRADIATIONS

5 PH-TA1-SD meeting Dosimetry and beam profiling Cartography/Dosimetry with Optically Stimulated Luminescence (OSL) materials: FAST EXTRACTION TEST mm mm 5x5 cm 2 beam 9x5 cm 2 beam Neutron reactor Vs Irrad2

6 PH-TA1-SD meeting Other activities 2003 Complicated irradiation and dosimetry: CMS ECAL crystals and fast extraction tests for CMS Beam Condition Monitor Summer Student (K.Visser) - NaI spectrometer software New storage facilities for radioactive material 2003/2004 New control hardware for the two shuttle systems Online database for certificates of outside institutes to handle radioactive material Development of a radiation monitoring system for CMS and other LHC experiments (several publications submitted) Laser systems for semiconductor detector testing 2004 New neutron irradiation zone (PSAIF) Scenario for taking over the T8 beam line in the PS East Hall (DIRAC experiment) in 2006

7 PH-TA1-SD meeting CERN-PS East Hall CERN PS-AD PSAIF -> 130 Gy/h (Si) + 1E12 n cm -2 h -1 3E11 n cm -2 h E13 p cm -2 h -1
