CP4 bake enclosure removed

Today MCE removed the CP4 bake enclosure and stored it in a connex container that Mark and Tyler cleaned out. The controls panel and heater/fan assembly are still in MY VEA and may stay there for storage. The pressure in the main volume slightly improved as a result. See plot. Current pressure = 2.40e-9 Torr.

I stripped the RGA + turbo manifold of all the heater tape, foil, etc. and made a first pass clean up. Area needs a good deep cleaning. I recommend continued use of face masks to avoid breathing in fiberglass floating in the air.

RGA scans will be logged soon.
