I’m going to toorcamp. Maybe I’ll see you there.

New Turbomolecular Pump
8 04 2009The new turbo pump just arrived. The Turbopump itself has has a 4.5″ conflat flange for an inlet. Attached to the turbopump inlet is a 4.5″ to 2.75″ reducer.
I think as a first step, I’m going to skip the heroics of putting the chamber on it’s side, and just buy a 2.75″ 90˚ conflat elbow. Cheap and easy to install. I realize this is not an optimal connection for the pump (skinny with a bend). But ultimately I have time, and if it takes days to get down to vacuum… so be it.

I’ve Moved
8 04 2009I’ve moved to a cheaper short term (one month) apartment to reduce my burn rate. Also did away with most of my personal possessions to keep light and mobil. So now the lab is my home base. I’ve got it setup:
I must return my work laptop soon, so I got a new macbook with 4G RAM, you can see on the desk.

YBCO Superconducting Cable
8 04 2009Very exciting. The YBCO arrived today. This is what $1,105.00 worth (13 Meters) of insulated YBCO superconducting cable looks like:
The ribbon itself is very very thin and flexible. Much more flexible than I was expecting. Here is a close up of the ribbon:
That’s just some scotch tape at the end.
The lead time for this YBCO is about 3 months. So you really have to order in advance.
Today I plan to order the first prototype of the chassis.
Also going to get the dewar flask filled with some liquid nitrogen and attempt to build a superconducting coil!
While we’re on the topic of superconducting cable. Would it be possible to buy a used MRI machine and extract the superconducting cable? Even if this is possible, it would be using low temp superconducting cable, which of course requires both liquid helium and liquid nitrogen.
