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

[Yi Qiang]

Hi,

I'm thinking of putting an infrared camera outside the vacuum chamber to 
monitor the temperature of the radiators and take images at low light 
condition. The camera can be put upstream (backward angle) so that it 
has both a good view of the radiator and low radiation background. I 
talked to Tim and he told me that it's pretty easy to put a quartz 
window on the vacuum chamber to let the camera see through. Regarding 
the camera itself, I did some quick search and found this
http://www.fluke.com/fluke/usen/Thermal-Imaging/ti-best-performance/Fluke-Ti32.htm?PID=56184
The fluke Ti32 fits our needs pretty well in term of specifications, 
although I'm not sure how to implement it into our online system. It has 
good temperature range and sensitivity, and the spatial resolution is 
about 0.5 mm if we put it 40 cm away from the radiator and higher 
resolution can be achieved by replacing its lens. The cost is about $9000.
Your comments a very welcome.

Cheers,
Yi
