None GPS Isotropic Angular Distribuyion

Dear all;

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/particle e-

/gps/ene/type Mono

/gps/ene/mono 500 keV

/gps/pos/type Point

/gps/pos/centre 0.0 0.0 -6.0 mm

/gps/ang/rot1 0 -1 0

/gps/ang/rot2 -1 0 0

##Angular Distribution

/gps/ang/type iso

/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.
