Question Detecting optical photons 

Forum: Hits, Digitization and Pileup
Date: 20 Apr, 2004
From: Phil Matvey <phmatvey@yahoo.com>

I'm a bit confused about how to use sensitive detectors when
the particle I need to detect is an optical photon. In my simulation,
I need to count photons hitting a steel box. I define the box as a
sensitive detector, but its ProcessHits function never gets called,
probably because box surface is treated as a dielectric-black material
boundary and the photon is stopped and killed without calling anything.
Defining an optical surface with zero reflectivity and 100% efficiency
doesn't help unless I also define a refraction index for steel - which
doesn't feel right, and will cause cerenkov photons beeng created inside 
the box, among other things.

What am I doing wrong ?

Thanks ...
