Hello,
When I use the /gps/source/list command after defining my particle sources, but before executing the /run/beamOn command in my Geant4 macro, I obtain the results below. As you can see, I have two particle sources in my script that use an arbitrary point-wise energy distribution for protons and electrons. However, the /gps/source/list command says that the energy of each source is 1 MeV. Does this command by default print 1 MeV for the particle energy regardless of the actual energy of the particles?
The number of particle sources is: 2
Multiple Vertex sources: 0 Flat Sampling flag: 0
source 0 with intensity: 110.92
Num Particles: 1; Particle type: e-
Energy: 1 MeV
Direction: (0,0,-1); Position: 0 0 80 cm
Angular Distribution: planar
Energy Distribution: Arb
Position Distribution Type: Plane; Position Shape: Circle
source 1 with intensity: 1
Num Particles: 1; Particle type: proton
Energy: 1 MeV
Direction: (0,0,-1); Position: 0 0 80 cm
Angular Distribution: planar
Energy Distribution: Arb
Position Distribution Type: Plane; Position Shape: Circle
Current source index:1 ; Intensity:1
My question is essentially the same as the one asked by a user several years ago that was unanswered: /gps/source/list results are not correct (?). I decided to create a new thread given how long ago the original post was made. Please let me know if I should instead comment on the same post (regardless of how long ago it was posted) in the future.
