[Halld-tagger] Thermal viewer/camera for the radiator

[Yi Qiang]

Hi Fernando,

Thanks for pointing it out. I think FLIR E60 may work, it has pretty 
good resolution and can also provide video streaming through USB
http://www.flir.com/cs/emea/en/view/?id=41959

As for the radiation damage, the backward angle will help reduce the 
radiation significantly and we can further lower the flux by putting the 
camera into a shielding block. Actually, for most of the Hall-A 
experiments, we put a camera to monitor the target ladder motion and 
they all survived as far as I know. A typical condition is a 10 uA beam 
hitting a 3% target which is about 3 orders of magnitude worse than our 
photon beam radiator.

Cheers,
Yi
