Hi, I am adding source in a macro with :
/control/foreach configure_source.mac pname “mu-”
/gps/source/add 1
/gps/source/set 1
/control/foreach configure_source.mac pname “mu+”
where configure_source.mac is :
/gps/particle {pname}
/gps/ang/type beam1d
/gps/ang/sigma_r 2.0 deg
/gps/ene/mono 10.0 GeV
After I do /gps/source/list and get
The number of particle sources is: 2
Multiple Vertex sources: 0 Flat Sampling flag: 0
source 0 with intensity: 1
Num Particles: 1; Particle type: mu-
Energy: 1 MeV
Direction: (0,0,-1); Position: 54.3839 0 139.794 m
Angular Distribution: beam1d
Energy Distribution: Mono
Position Distribution Type: Point; Position Shape: NULL
source 1 with intensity: 1
Num Particles: 1; Particle type: mu+

Direction: (0,0,-1); Position: 54.3839 0 139.794 m

The printed energy is not correct. But running I see it is ok:
→ Event 0 starts.
