[Gate-users] monoenergetic electrons source for dosimetry?

[Bryan McIntosh]

Hi Ashok,

Check the units of your electron source's energy; 0.015 eV is EXTREMELY
low, so there's no dose deposited since there's no ionization occurring!
Double-check the energy of the beam you wish to simulate and enter that
value instead of this very small one.

Best regards,

-Bryan
