I would like to generate a an isotrpoic beam. Therefore, I defined a point source which should generate istropic electrons (uniform angular distribution) . This is my .mac file:
##define the particle type
/gps/ene/mono 500 keV
/gps/pos/centre 0.0 0.0 -6.0 mm
/gps/ang/rot1 0 -1 0
/gps/ang/rot2 -1 0 0
/gps/ang/mintheta 0 deg
/gps/ang/maxtheta 65 deg
/gps/ang/minphi 0 deg
/gps/ang/maxphi 360 deg
But this does not generate a uniform angular distribution of the e- beam (See Fig1). I do not know why. It should generate a uniform distribution and not Gaussian-like distribution. Where is the mistake?
Thank you very much in advance.
