Yep, and all fitted to the chamber and stand, but sadly still in
storage, was just about ready to do a first pump down test when I
had to move, three plus years ago. I NEED A SHED!
Drew, the hurricane was ~1100miles north of my present location,
thankfully! Didn't I help you install those baffles? I seem to
remember doing something along those lines.....
Well I guess it's about time I got my gear packed and headed off to
uni.

Thomas...
If my memory isn't totally bananas, I sent you a Diffusion
pump, a cooled chevron baffle and a gate valve in a large
crate a few years back. You should have everything that
Drew is mentioning.

because they get so cold they sweat. The water in the
jacket is like 32 degrees now. The pump down time with the
heaters on went from 4+ hours to about 45 minutes and the
overall vacuum seems devoid of oil vapor. I saw no soot on
the windows for the first time ever. I only have the one
run to judge by ( using the new coolant system ) but it
really looks like it makes a huge difference in the
chamber's abilities.
