Hi Josh and Cassandra,

You can simulate an alpha source the same way you simulate a beta or a gamma source. For example:

/gate/source/addSource mybeam gps
/gate/source/mybeam/gps/particle alpha
/gate/source/mybeam/gps/pos/type Beam
/gate/source/mybeam/gps/pos/rot1 0 1 0
/gate/source/mybeam/gps/pos/rot2 1 0 0
/gate/source/mybeam/gps/pos/shape Circle
/gate/source/mybeam/gps/ene/mono 5 MeV

My regards,
Eslam

Hi Josh,

No I didn't! Although I don't know if that means it isn't possible, I didn't spend too much time looking into it because I found an alternate way for me to do what I needed to do. I feel like it should exist, although I also don't think alphas are studied too commonly using Gate.

Best,
Cassandra

Hi Cassandra, did you ever figure out a way to define a pure alpha source? I’d like to know how to do it too.

Hi everyone,

I know it is possible to define a beta/gamma source with Gate, using
UserSpectrum and the "/gate/source/spectrumname/gps/particle beta"
command, for example. Is it possible to do this with alpha particles as
well? There is nothing in the documentation about it, but I think Geant4
is capable of doing things like that, so I was wondering if there was a
way..

Similarly, it is possible to use the "ion source" for an alpha emitting
isotope, but tell Gate to not simulate gammas/betas/anything besides
alphas?

Thank you!

Best,
Cassandra
