Failed to simulate X-ray generation from X-ray tube

there is another topic open where the author also used the approach to replace the physics list with a different one, and had unexpected results: Replace part of reference physics list - #4 by afinch

could you check if you get the same when you directly use the respective physics list? would be very interesting to see, I will probably need to simulate xray tubes as well… :slight_smile:

 // Physics list
  G4VModularPhysicsList* physicsList = new G4EmStandardPhysics_option4();
  physicsList->SetVerboseLevel(1);
  runManager->SetUserInitialization(physicsList);

in the macro, you might then also need adjust the production cuts to have the same settings as in @idrissi_abdelghani physics list:

/run/setCutForAGivenParticle gamma 1 micrometer
/run/setCutForAGivenParticle e- 1 micrometer
