I am trying to make a cylindrical gamma source that has more lines with different intensities.
For that, I created a GPS.mac file but I don’t know how to add those lines and intensities, I don’t know the syntax for that and Chatgpt gives me wrong suggestions.
Here is my GPS.mac file:
/gps/verbose 0
/gps/particle gamma
/gps/pos/type Volume
/gps/pos/shape Cylinder
/gps/pos/radius 1.22 cm
/gps/pos/halfz 1.1 cm
/gps/pos/centre 0 0 -1.22 cm
/gps/ang/type iso
/gps/ene/type Mono
/gps/ene/mono 48.67 keV
this comes without any warranty. I just found an old file of file where *I think* it does what you want it to do.
