[dsg-hallb_svt] Debugging SVT DAQ

[Brian Eng]

I didn't change the chiller set points, but that ice was already built up as the bag was slightly peeled back.

I'm not sure the picture conveyed it very well, but the ice build up was fairly thick.

Thank you for your help, Brian

A question about icing. Did you warm up the SVT for a few hours before opening the plastic bag? This was in the instructions I sent last week. The detector should be warmed up before any work on L1C. With nitrogen purging and the detector at RT there should be no condensation. After the work is done, the chiller should be set to the same temperature as before (currently -10 C).

Hi Yuri,

Here's what I've noticed so far with R1 M2.
