[Gate-users] monoenergetic electrons source for dosimetry?

[Ashok Tiwari]

Hi, 

I am trying to simulate the monoenergetic electrons in the water phantom. Following macro is what I am using as a definition of monoenergetic electrons source:

/gate/source/addSource monoenergetic_electron                   gps
/gate/source/monoenergetic_electron/gps/particle                e-
/gate/source/monoenergetic_electron/gps/energytype              Mono
/gate/source/monoenergetic_electron/gps/monoenergy              0.015 eV
/gate/source/monoenergetic_electron/gps/angtype                 iso
/gate/source/monoenergetic_electron/gps/centre                  0. 0. 0. mm
/gate/source/monoenergetic_electron/gps/type                    Point
/gate/source/monoenergetic_electron/attachTo                    my_phantom
/gate/source/monoenergetic_electron/visualize                   1000 yellow 10

With this definition, I am getting all zeros in my dose matrix. Could anyone tell me, what information I am missing in above definition?

Regards, 
Ashok
