Question CsI caloriemeter, an event never ends! 

Forum: Processes Involving Optical Photons
Date: 10 Oct, 2012
From: Hanjin Kim <Hanjin Kim>

Hello, sir.

I'm pretty new for geant4, so please excuse my poor description of the situation.

I'm trying to simulate an CsI caloriemeter wrapped with Al layer. I've put some boundary properties such as REALINDEX & IMGINDEX of Al on the skin surface of CsI crystal and using the physic list of LXe example with some modification. I spent some time to figure out how to make the reflection take place on a boundary.

When I try to run an event, it seems all the processes work fine(Reflection takes place!) but photons are trapped inside the Al layered box and never die. It looks very bad that any photon would escape the Al chamber because I'm trying to make the crystal as real as the actual CsI ECL crystal of Belle, it is rather natural that there's some energy loss. What is the problem here?

I think the problem with photons that never die is caused by the fact that I didn't put absorption length property on CsI, but I can't find any information about that factor on the internet.

And is it possible to gather two or more physics list into one? for instance, QGSP_BERT + userphysicslist.

Thank you for your time.
