Updates from:
Will – Made a new parts list since the bayonet/vacuum insulated fitting is delayed. This new parts list will allow us to start testing with a less efficient connection before the vacuum insulated line gets in. The new heat exchanger is finished, plan on cleaning it with methanol or isopropyl alchohol followed by acetone. We have a 0.1″ indium die that we can use for seals. The old purifier setup from 416 is pressure rated to be able to test with. He has calculated a 1 meter heat exchanger length for the water cooled HE. Viscojet does not want to work with us to get their product to use as a JT valve. We can make a valve ourselves or get a small, precise needle valve to be able to use.
TO DO: Polish new heat exchanger, Cut existing helical coils to be useable for the water bath HE. Look at getting a needle valve to use as a JT.
Greg – Parts have been found for pressure testing of the Haskel compressors, we need one short length of 1/4 stainless pipe pressure rated to at least 1400 psig to be able to test.
TO DO: Order the 1/4 stainless pipe section
Dustin – Presentation on the NFPA and WAC codes and how the Quonset Hut site meets codes and standards. NFPA codes are met with the siting locations, WACs will require minor modifications – movement of the compressor in TFRB. Fire hazard signs will need to be posted – no smoking signs, etc. Location options are discussed, and a location is proposed.
TO DO: Adjust the image to move to the new location. Update some of the slides with necessary modification that will need to be made. Update the slide deck to make the presentation Relevent, Credible, and Efficient. Add the coal yard as a secondary backup site.
Jose – Working on trying to contact Stirling Cryo, but having issues. Still working on getting CAD layouts of the container worked out.
TO DO: Work to make a CAD mockup of the vacuum insulated line that can be easily adjustable so we’re ready to send it off when we get the final information.
Sam – Working on the power requirements for the fans – it seems the the power difference between the half speed and full speed of the fans is not very much, so it will make the most sense to continue with just full speed fans. He has a meeting with facilities to talk about wiring and the needs of getting alll of the electrical set up for the station. Ideally initial power should be able to be obtained by just plugging into one of our high voltage outlets.
TO DO: Talk with the facilities guy tomorrow morning.
