<p>Hi David, <br>
</p>
<p><br>
</p>
<p>first of all, thank you for your prompt response!<br>
</p>
<p><br>
</p>
<p>you can find my macros in the attachement. I marked all geometry and material sepcific details with XXX.</p>
<p><br>
</p>
<p>What I tried at first was to move the whole chamber in my water tank along the x-Axis with the following commands:<br>
</p>
<p><br>
</p>
<div>/gate/ppcyl/moves/insert translation<br>
/gate/ppcyl/translation/setSpeed 0.5 0. 0. mm/s</div>
<br>
<div>/gate/ppspi/moves/insert translation<br>
/gate/ppspi/translation/setSpeed 0.5 0. 0. mm/s</div>
<p><br>
</p>
<p>and then to simulate over a certain time in order to not move the chamber outside of the mother volume (water tank):</p>
<p><br>
</p>
<div>/gate/application/setTimeStart 0. s<br>
/gate/application/setTimeStop 300. s</div>
<br>
<p>I added the DoseActor to my sensitive air volumes <span>airvolcyl</span> and <span>
airvolcap. That's where I'd like to measure my dose. Then I kinda figured out that Gate wasn't able to calculate my dose during the movement. There was no error in Gate but the output files were empty.</span></p>
<p><span><br>
</span></p>
<p><span>What I tried next was to just measure the Dose with the DoseActor at just one spot in the water tank in my entire sensitive volume. Here I am a little confused with the settings. My sensitive volume consists of two daughter volumes (1 the cylinder
and 2 the spherical cap). <br>
</span></p>
<p><span>Do I have to add one actor for each daughter volume (so in total 2 actors)?</span></p>
<p><span>And do I neccessarily have to do "setSize" when I want to add the DoseActor to my whole volume?</span></p>
<p><span><br>
</span></p>
<p><span></span>Best regards,</p>
Anna</div>
<br>

<span style="font-size:11.0pt; font-family:"Calibri",sans-serif; color:#1F497D">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.</span></p>

<span style="font-size:11.0pt; font-family:"Calibri",sans-serif; color:#1F497D">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)?</span></p>
<p style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: "Times New Roman", serif;">
<span style="font-size:11.0pt; font-family:"Calibri",sans-serif; color:#1F497D">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?</span></p>

<span style="font-size:11.0pt; font-family:"Calibri",sans-serif; color:#1F497D">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.</span></p>
