Thanks, Marc. That should work well. We can get a week or so running in well before GENRP starts.</div>

I am working towards installing the expansion unit in the hall and the new cRIO in the counting house. I plan to have them installed an up and running by early February. Then we can start up the heaters.<br>

Right now I am focused on wrapping up the prototype design for the power supply interface chassis, which will connect the power supplies to the controls, safety system, and heaters. Once the design is finished and reviewed I can order parts for the chassis.</div>

Hi Marc,</div>
<div class="x_x_elementToProof" style="font-family:Aptos,Aptos_EmbeddedFont,Aptos_MSFontService,Calibri,Helvetica,sans-serif; font-size:12pt; color:rgb(0,0,0)">
I would like to turn on the prototype heater system again whenever that is possible from the controls standpoint. I have built and installed a full cooling system (see pump and enclosure below) and would like to get some data on the level of pressure and flow
required to give sufficient cooling to an enclosed system similar to what we will have in ECal. We can meet in person to discuss this if you want or we can discuss it in our Thursday weekly meeting. I'm not sure what needs to be installed and or replaced to
get the controls functioning again.</div>
