<p><font size="+1">Dear All,</font></p>
<p>Here is the current status of the SVT integration. We have and
issue with R1S2 registers 17, 18 failing the register test. Last
Friday this module was tested several times and it was
operational. Debugging it might require swapping the data cable to
check if it is causing for the problem. Also it would be helpful
to identify which pins of J2/J3 connectors are needed for these
registers. <br>
</p>
<p>The SVT will be cold (set auto temperature for ON and OFF to -10
C) all the time when there is no work on the detector to reduce
reverse annealing. Two plastic bags with nitrogen purging protect
the detector from condensation. Interlocks are enabled. Two
nitrogen bottles are connected in parallel for purging to reduce
humidity inside the barrel. When working on L1C connectors SVT
should be wormed few hours in advance to +20 C and plastic covers
opened when humidity is below 50%. Purging could be increased for
a short time o 3 lpm if needed. For long standby without LV/HV
power it should be kept at 2 lpm. It will be very helpful to have
remote control of the nitrogen flow.</p>
<p>Current status: SVT is cold with coolant at -10 C, humidity below
40%.<br>
