[Gate-users] a question about radioactive source simulation with Gate version 6.2

[Pietrzyk, Uwe]

Hi Masoud Masoudi,

perhaps you could check the two attached files and compare it with yours.
One of the files (sources_ion_universal.mac) is taken from the
EduGATE - Spectro_Release_2014, you can easily download from
the OpenGATE Web-Page and which I have tested for GATE 6.2 and 7.0.
(http://www.opengatecollaboration.org/EduGATE)

Also, I think you have to type keV instead KeV, but I am not sure, whether this
is really relevant.

Let me know, whether this was helpful!

Kind regards and best wishes,

Uwe Pietrzyk

Dear Prof. Dr. Uwe Pietrzyk

Thank you for your kind help. I have used your recommended commend in Gate version 6.2 but unfortunately radioactive decay is not happening! I do same with Gate version 6.1 and radioactive decay happened. I think the reason for this observation is the warning that is written in manual:

# WARNING - DEBUG - New command line to debug the use of ion particle type
/gate/source/F18/useDefaultHalfLife
Please help me to solve the problem. Thank you.

Best Regards,
Masoud

Hi Masoud,

did you include the following line into your
physics definitions?

/gate/physics/addProcess RadioactiveDecay

This has to be added for Gate 6.2 and also for 7.0

Please try.

Kind regards,

Uwe Pietrzyk

Dear all
I need to simulate a radioactive source with Gate version 6.2. I have used this command from manual. But radioactivity decay is not happening. Can anyone help me? Thank you.

/gate/source/NAME/GPs/particle ion
/gate/source/NAME/GPs/ion 9 18 0 0
/gate/source/NAME/GPs/monoenergy 0. Kev
/gate/source/NAME/setForcedUnstableFlag true
