I'm currently playing with Gate v7.1. 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. I tried to use /gate/physics/Electron/SetCutInRegion to set energy threshold lower than 250 eV, but it was not working. I checked the source code and found limit for production cuts table ("source/physics/src/GatePhysicsList.cc", 80L). But I'm not sure whether I could change it or not. This is strange to me because Geant4.10 Penelope physics has minimum low e- energy down to 100 eV but Gate does not support. Is there any method I can set energy threshold lower than 250 eV? I appreciate any reply in advance. Regards, Wonmo Sung </div> </body> </html>
