<div dir="ltr">Dear GATE's users,<div><br></div><div>I am coming back to you, always about the same problem I have had for several weeks (mouths..) : the simulation of radioluminescence of air by alpha particles. I would like to simulate the emission of UV photons from the interaction of secondary electrons with air (the electrons are coming from successive ionisation of air by alpha particles).</div><div><br></div><div>By the help of the documentation (<a href="https://opengate.readthedocs.io/en/latest/general.html">https://opengate.readthedocs.io/en/latest/general.html</a>) I tried 2 differents ways :</div><div><br></div><div>- First one, the use of fluorescence phenomenon explained here in the 5.4.4 section <a href="https://opengate.readthedocs.io/en/latest/generating_and_tracking_optical_photons.html#defining-material-properties">https://opengate.readthedocs.io/en/latest/generating_and_tracking_optical_photons.html#defining-material-properties</a></div><div>Nothing happens. No optical photons are emitted, from the alpha particles interactions nor from the secondary electrons interactions. Is this kind of phenomenon available only for photons as a primary event ? <br></div><div><br></div><div>- Second one, the use of scintillation phenomenon, explained here in the 5.4.1 section : <a href="https://opengate.readthedocs.io/en/latest/generating_and_tracking_optical_photons.html#scintillation">https://opengate.readthedocs.io/en/latest/generating_and_tracking_optical_photons.html#scintillation</a></div><div>In this case, I succeed to produce optical photon, but following alpha and electrons interactions. I would like to produce optical photons only from electrons interactions. </div><div><br></div><div>Does anyone have any ideas on how I can fix my problem ?</div><div><br></div><div>Thank you.</div><div>Déborah</div><div><br></div></div>
