Hi Don,
<div><br>
</div>
<div>While Marc is out on medical leave we’re continuing to work on getting the system up and running. I don’t think additional people would help as really there’s only room for one person to work connecting the TC anyway.</div>
<div><br>
</div>
<div>Do you have time to meet so we can go over some of the issues we’ve run into/noticed?</div>
<div><br>
</div>
<div>Thanks</div>
<div>Brian<br>

I wanted to give you an update on the status of the heater system from my side. I am working on running the heater power cords from the bunker to the platform. That should be completed tomorrow. Aram finished running all the thermocouple cables including the
ambient temperature cable today and plans to finish connecting them up to the thermocouples in the morning. If you could use help connecting up the remaining 140 thermocouples to your DAQ, let me know. Aram has offered to help with that if you can provide
instructions. </div>

The ambient temperature safety controls cable has three thermocouples on the front of the detector monitoring air temperature near the front plates. They are located near in the bottom center, middle center and top center regions of the detector. The rear has
five thermocouple cables and you can choose which to monitor. They are epoxied to the patch panel aluminum frame in the back of the enclosure and should monitor the ambient temperature of that region. I put 4 of them in the center of the detector above the
midline. A fifth one was placed closer to the top. I believe you only plan to monitor one of these and you can choose which you want.

Ellen has wired up the Emergency Off button upstairs in the Counting House and I will ask her to run a wire to the bunker.</div>

It looks to me that by the end of tomorrow, we will be done or close to complete with this system on my end. Let me know if you can use help on your end.</div>
