Liam David Fusor Update

Cost to repair is most likely what they are referring to. Is it cost effective.

[Liam David]

No, they're willing to inspect it for free to see if it's repairable, but one of the (technicians?) emailed me and said it's not.

The new TCP-040 controller arrived today, and I bolted the chamber together to do a vacuum test. The roughing pump only reached about 350mtorr due to outgassing, but the turbo pump pulled the chamber to 1E-5 torr in just a few minutes. The turbo accelerated fine and has a high, almost piercing pitch as it does so. At one point during deceleration it did sound like rotating metal contacted something in the pump, but no other noises were made afterwards.
In the manual for the turbo pump, it says that if the pump is mounted off of the vertical axis, then the outlet port should not exceed 20 degrees side-to-side from pointing downwards. What is the reasoning behind this?
