Energy loss calculation for protons in the E and dE detectors
E width 3 cm
dE width 0.3 cm
p=1000[MeV/c] T= 433[MeV] Eloss(E)= 9.3 [MeV] Eloss(dE)[MeV]=0.93
p=250[MeV/c] T= 33[MeV] Eloss(E)=33-5.7=27.3 [MeV] Eloss(dE)[MeV]=5.7
minimum ion Eloss(E)=6.6[MeV] Eloss(dE)=0.6[MeV]
protons punch-through point in the E plane [3 cm] at T=45 MeV = 294 [MeV/c]
commission guidelines -
we should try to set threshold for the E bars between 6.6[MeV] -> 9.3[MeV] = 8 [MeV]
max energy protons we would like to record is 45 MeV.
full range of adc is 4000
this gives -
45 MeV = 3000 ch
1 MeV = 66 ch
6 MeV = 530 ch (threshold)
