M.Moll, M.Silari, H.Vincke – 3.April Proton Facility -- Who answered ?  In total 51 forms filled:  Colleagues from Experiments: Almost all (~34/37) have used the IRRAD facilities before!  Colleagues from RadMon: All (2/2) have used facility before!  Colleagues from Machine: (Almost) nobody (~0/12) has used the IRRAD facilities before!  Have colleagues that filled the form used the present proton irradiation facilities (IRRAD) ?

M.Moll, M.Silari, H.Vincke – 3.April Proton Facility -- Who answered ? 37 forms filled by colleagues working for the Experiments:  Feedback for proton facility dominated by Inner Tracker community which Experiments? which detector community?

M.Moll, M.Silari, H.Vincke – 3.April Proton Facility: Proton Momentum  4 times : 450 GeV/c needed, 24 GeV/c excluded (all from ‘Machine Community’)  5 times : 24 GeV/c needed, 450 GeV/c excluded (all from ‘Experiment Community’)  1 invalid answer (No preference for momentum, but indicated that other would be excluded) 9 from ‘Machine Community’ 1 from ATLAS MUON (G.Mikenberg) (However, not indicated that 24 GeV/c would be excluded) all from ‘Experiment Community’  Conclusion from statistical analysis of Questionnaire:  Machine Community needs 450 GeV/c and Experiment Community needs 24 GeV/c  Conclusion  Need to understand reasoning: Why do people think 24 or 450 GeV/c are excluded?  Part of the request for 24 GeV/c p created by fact that presently such a facility is existing

M.Moll, M.Silari, H.Vincke – 3.April Reminder: Charged hadron field in Experiments  Inner Detector (ATLAS SCT)  Hadron Calorimeter 23 GeV 450 GeV

M.Moll, M.Silari, H.Vincke – 3.April Proton Facility: Fast or Slow Extraction?  Conclusion:  Seems that this question is difficult to understand: Members of same community give quite different answers!  Need to look into argumentation!  Pulsed radiation (22%)  Continuous radiation (39%)  Need both (8%)  No preference (32%)

M.Moll, M.Silari, H.Vincke – 3.April Proton Facility: Required Fluence  Required maximum integrated proton fluence:  2 x p/cm 2 (94% require this or less)  3 answers above this limit: 10 19, 10 23, 100MGy  Maximum fluence rate  Driven by type of experiment: Irradiation hardness test (rather driven by time needed to reach the max fluence than by physics constraints for the irradiation experiment) Fast extraction, thermal shock type experiments
