<br>
Thanks for pointing it out. I think FLIR E60 may work, it has
pretty good resolution and can also provide video streaming
through USB<br>

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.<br>

just one comment. If the neutron radiation is of any higher
level these cameras<br>
will probably die very fast.<br>

Hi,<br>
<br>
The model Ti125 does support video streaming through USB:<br>
<a moz-do-not-send="true" class="moz-txt-link-freetext"

However, its resolution is only 3.3 mRad, about 3 times worse
than the previous model.
<div class="moz-cite-prefix">I will continue to search for
other models if we really like this idea.<br>

Thanks,<br>

yes, it's true for this model ...<br>

Hi Yi,<br>
<br>
Is it correct that the only way to get an image off of
this (besides looking at the built in screen) is to save
it to an SD card and then take that out to use in a PC
card reader?<br>

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>
