Gamma will NOT make any energy deposition. Once compton scattering occurs, the secondary electron could be lower than the production cutoff (I guess) so that the kinetic energy of the recoiled electron could be merged into the energy deposition of the primary gamma. Thus there is no strange behavior here in this user report. |
I want to stored the total energy deposited during a step. I introduce a limit on the step length in my detector construction class and in my Sensitive Deyector(SD) I see, for each step, the particle name, the step length, the total energy deposed during the step. As you can see in this list, only one deposition is stored from the Densitive Detector ( there is the output from SD class) ******************************************************************************** * G4Track Information: Particle = gamma, Track ID = 1, Parent ID = 0 ******************************************************************************** Step# KinE(MeV) dE(MeV) StepLeng TrackLeng NextVolume ProcName 0 0.356 0 0 0 CapsulePhys initStep 1 0.356 0 0.561 0.561 WaterBoxPhys Transportation 2 0.356 0 1 1.56 WaterBoxPhys User Limit 3 0.356 0 1 2.56 WaterBoxPhys User Limit 4 0.356 0 1 3.56 WaterBoxPhys User Limit 5 0.356 0 1 4.56 WaterBoxPhys User Limit 6 0.356 0 1 5.56 WaterBoxPhys User Limit 7 0.356 0 1 6.56 WaterBoxPhys User Limit 8 0.32 0.0364 0.793 7.35 WaterBoxPhys LowEnCompton gamma 0.0363845 0.792825 (this from SD class...) 9 0.32 0 1 8.35 WaterBoxPhys User Limit 10 0.32 0 1 9.35 WaterBoxPhys User Limit . . 22 0.32 0 1 21.4 WaterBoxPhys User Limit 23 0.231 0.0886 0.13 21.5 WaterBoxPhys LowEnCompton (why no messages from Sensitive Detector about energy deposition?) 24 0.231 0 1 22.5 WaterBoxPhys User Limit 25 0.231 0 1 23.5 WaterBoxPhys User Limit 26 0.122 0.109 0.000388 23.5 WaterBoxPhys LowEnCompton (why no messages from Sensitive Detector about energy deposition?) 27 0.122 0 1 24.5 WaterBoxPhys User Limit . . ### pop requested out of 0 stacked tracks.
