1. M.Moll, M.Silari, H.Vincke – 3.April 2008 -1- Feedback  In total 134 forms filled: 2.4.2008

2. M.Moll, M.Silari, H.Vincke – 3.April 2008 -2- 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) ?

3. M.Moll, M.Silari, H.Vincke – 3.April 2008 -3- 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?

4. M.Moll, M.Silari, H.Vincke – 3.April 2008 -4- 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

5. M.Moll, M.Silari, H.Vincke – 3.April 2008 -5- Reminder: Charged hadron field in Experiments  Inner Detector (ATLAS SCT)  Hadron Calorimeter 23 GeV 450 GeV

6. M.Moll, M.Silari, H.Vincke – 3.April 2008 -6- 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%)

7. M.Moll, M.Silari, H.Vincke – 3.April 2008 -7- Proton Facility: Required Fluence  Required maximum integrated proton fluence:  2 x 10 16 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

8. M.Moll, M.Silari, H.Vincke – 3.April 2008 -8- Proton Facility: Purpose of irradiation tests  Type of equipment  44% Detector and detector components  26% Material tests  12% Accelerator components  9% Radiation monitors and dosemeters  Type of test  55%Radiation hardness test  28% Detector and equipment tests  5%Dosemeter calibrations

10. M.Moll, M.Silari, H.Vincke – 3.April 2008 -10- Proton Facility: Facility Infrastructure  Fraction of answers asking for  75 % Electricity  61 % Connections for read out electronics  47 %Beam extraction signal  45 %Temperature controlled environment  42 %Storage area  also asked for cold storage space for activated material (-30°C)  35 %Scanning system  28 %Preparation area  16 %Crane  16 %Cryogenics  Others:  liquid metal handling (mercury)  cooling water

11. M.Moll, M.Silari, H.Vincke – 3.April 2008 -11- Proton Facility: Beam time required (I)
