<p dir="ltr">Dear all,</p>
<p dir="ltr">I want to simulate the laser tissue interactions using Gate. For this purpose, energy threshold limit should be a few eV. Does Gate handle such interactions? If so, which physics model should I use? Thanks in advance.</p>

<p>Dear gate-users</p>
<p><br>
</p>
<p>Hello! <span style="font-size:12pt">I'm currently playing with Gate v7.1.</span></p>
<p><br>
</p>
<p>I would like to set an energy threshold limit lower than 250 eV (e.g., 100 eV). However, Gate seems to have minimum energy threshold, 250 eV.</p>
<p>I tried to use </p>
<p><br>
</p>
<p>/gate/physics/Electron/SetCutInRegion </p>
<p><br>
</p>
<p>to set energy threshold lower than 250 eV, but it was not working.</p>
<p>I checked the source code and found limit for production cuts table <span style="font-size:12pt">("source/physics/src/GatePhysicsList.cc", 80L)</span><span style="font-size:12pt">. But I'm not sure whether I could change it or not.</span></p>
<p>This is strange to me because Geant4.10 Penelope physics has minimum low e- energy down to 100 eV but Gate does not support. </p>
<p><br>
</p>
<p>Is there any method I can set energy threshold lower than 250 eV?</p>
<p><span style="font-size:12pt">I appreciate any reply in advance.</span><br>
</p>
<p><br>
</p>
<p>Regards,</p>
<p>Wonmo Sung</p>
