[Gate-users] Profiles and depth dose curves with Ion chamber in water tank

[Boersma David]

Hi Anna,

It may depend  a bit on what exactly you wish to study with your simulation. Typically we use indeed the dose actor for depth dose curves. But if you would like to study in detail the geometrical and other aspects of the measurements, then you may indeed have to simulate the ionization chamber and move it around.

Could you share your macro with us (maybe remove/hide the geometrical details of the ionization chamber, if those are proprietary and you got them under and NDA, etc)?
And could you elaborate a bit more about what kind of trouble you are having: what did you try and which error did get from Gate? Or if there was no error, then in which ways was the output disappointing?

>From the little info that you give us, I think that I would, in your situation, not run a single simulation in which the IC is moved around, but instead run many separate simulations, one for each of the positions of your ionization chamber, and combine the results afterwards.

Good luck!
David

Dear Gate Users,

I've been trying to simulate an ionization chamber moving in a water tank in order to get dose profiles, depth dose curves etc. I've simulated my chamber including its effective volume. But I am having trouble recording particles or dose in this volume along the axis that the chamber is moving (with /gate/Chamber/moves/insert translation)
Is this even possible with Gate? Do I have to use the DoseActor?

Best regards,
Anna
