Hi,<br>
<br>
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<br>

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.<br>
Your comments a very welcome.<br>
<br>
Cheers,<br>
Yi<br>
