I send them again in text format. If someone could answer me, thanks in advance. Hi, I defined a new material as: Macor: Zeff=10.047 ; A=20.253 g/mole ; d=2.20 g/cm3 ; state=solid +el: name=auto ; n=1 in the GateMaterials.db for a structure I named outWin. The Gate display when setting this new material is: /gate/outWin/setMaterial Macor Macor : WARNING from G4Element::G4Element ! Trying to define an element as a mixture directly via effective Z. Is my definition wrong? Has this message consequences on physics processes? Thanks a lot for your reponses.

It consists of a block of lead (9cm thick), and I shoot gamma-ray (511keV, 10Bq for 1 sec) in one direction (Source-Surface Distance=10cm). I have no phantom. I set electron cut to 1 km, X- and Delta-Ray cuts to 1 GeV. I activate only photoelectric and Compton effects (low energy for both). I finally obtain 14 events. I cannot understand why I have so many Compton effects (20 single diffusions and 7 double) with nCrystalCompton (on the Hits branch) (attached) whereas I have only 10 LowEnCompton on the processName sheet (attached). Could someone explain it to me? The GATE display gives me well 10 Compton. Moreover, on the Gate display, I can't understand this lines: ********************************************************************************************************* * G4Track Information: Particle = gamma, Track ID = 1, Parent ID = 0 ********************************************************************************************************* Step# X(mm) Y(mm) Z(mm) KinE(MeV) dE(MeV) StepLeng TrackLeng NextVolume ProcName 0 0 0 0 0.511 0 0 0 world_P initStep 1 100 -1.22e-14 -6.12e-15 0.511 0 100 100 level1_P Transportation 2 105 -1.29e-14 -6.46e-15 0.349 0.162 5.43 105 level1_P LowEnCompton 3 108 -1.76 4.19 0.148 0 5.38 111 level1_P LowEnCompton :----- List of 2ndaries - #SpawnInStep= 1(Rest= 0,Along= 0,Post= 1), #SpawnTotal= 1 --------------- : 108 -1.76 4.19 0.202 e- :----------------------------------------------------------------- EndOf2ndaries Info --------------- 4 108 -1.36 3.05 0 0.0158 1.39 112 level1_P LowEnPhotoElec :----- List of 2ndaries - #SpawnInStep= 1(Rest= 0,Along= 0,Post= 1), #SpawnTotal= 2 --------------- : 108 -1.36 3.05 0.132 e- :----------------------------------------------------------------- EndOf2ndaries Info --------------- ********************************************************************************************************* * G4Track Information: Particle = e-, Track ID = 3, Parent ID = 1 ********************************************************************************************************* Step# X(mm) Y(mm) Z(mm) KinE(MeV) dE(MeV) StepLeng TrackLeng NextVolume ProcName 0 108 -1.36 3.05 0.132 0 0 0 level1_P initStep 1 108 -1.36 3.05 0 0.132 0.0428 0.0428 level1_P eIoni ********************************************************************************************************* * G4Track Information: Particle = e-, Track ID = 2, Parent ID = 1 ********************************************************************************************************* Step# X(mm) Y(mm) Z(mm) KinE(MeV) dE(MeV) StepLeng TrackLeng NextVolume ProcName 0 108 -1.76 4.19 0.202 0 0 0 level1_P initStep 1 108 -1.76 4.19 0 0.202 0.0826 0.0826 level1_P eIoni >>> Event 3 Why Gate tracks the electron #2 whereas it comes from a Compton effect?
