we've installed:
- the new stack -see earlier post with measured TF
- both copper radiation shields
- one shield has a NiChrome heater wrapped around (the other one not as we first want to see if we need more/less power, but calculation says this one should be right)
- three temp sensors (AD590), two on the shield with heater, one on the one without
- those sensors won't be used for temp control, only for temp and gradient monitoring and/or safety shutdown (if required)
- cable from D-SUB feedthrough to rack breakout terminal
window is back on and pumping down over the weekend. Thermal insulation for vacuum chamber is back in place, so we should be ready to go for a new measurement on Monday afternoon after installation of the beat breadboard
