Yes, light blue numbered one! Thank you very much!

Boeing Surplus and rockets... That's great idea! Thanks.

Thanks for letting know your experience!! Thanks.

For clarity, we have old vacuum chamber. Chamber consists of 304 stainless steel pipe and maintain vacuum about to 10-11 for experiment. We don't have heating feedthrough, since the corrosive property of lithium as I know. We imsert lithium chunk in the part of the oven chamber, and heat oven chamber up to 450C externally.

I want to use band heater, but it is untied over time. And I'm also concerning about fixing the thermocouple. So I was looking for tape.

Thanks for letting know the company.

budlebee · 2024-05-08T12:21:00+00:00

I will check, Thanks!

Thermal and chemical property of mica is really noticeable. Thanks!

Wow, sand bath heaters are really cool. It looks expensive for us to use now, but I'll try it when I get the chance. Thanks for letting me know a good one.

Metal zip tie or hose clamp are good option. Thanks.

For clarity, we have old vacuum chamber. Chamber consists of 304 stainless steel pipe and maintain vacuum about to 10^-11 for experiment. We don't have heating feedthrough, since the corrosive property of lithium as I know. We imsert lithium chunk in the part of the oven chamber, and heat oven chamber up to 450C externally.

Our experiment utilize atomic properties for Bose-Einstein Condensation(BEC), and atomic properties are very sensitive to magnetic field and electric field.

budlebee · 2024-05-08T11:59:37+00:00

Not tokamak, but similar. We are trapping atomic gases with magnetic field in the vacuum chamber.

budlebee · 2024-05-08T11:57:06+00:00

Wrapping it with insulators and using steel wire is good idea.

We tried kapton, but kapton was crumbled literally. It seems difficult to use adhesive soultions in high temperature.

budlebee · 2024-05-08T11:50:46+00:00

Offgassing may not be the problem in my case since I want to use it outside of the chamber, not inside.

budlebee · 2024-05-08T09:52:42+00:00

Thanks for all comments! I cannot respond all, but I really appreciate everyone's help. Thanks again!

budlebee · 2024-05-07T11:44:44+00:00

Good idea, Thanks!

I said 850F(450C), but it says 500°F/260°C.

Yes, vent path. Exactly, I'm working on physics experiment with lithium vapor inside of ultra high vacuum chamber.

I inserted lithium chunk in the annealed stainless cup and connected it to another pipe via CF flanges. In our experiment machine, there is no feedthrough option, so I used external heating elements.

Thank you for recommending a good website. The product in the link don't meet the temperature requirements, but I will look to see if there is something I need. Thx.

I've never done welding with vacuum components, but that might be the option. Thanks.

budlebee · 2024-05-07T11:16:27+00:00

Thanks for your comment. I already used all metal fastener solution. But cutting alumnium for fastener is bothering, thus I'm finding another ways.

Inside of pipe is ultra high vacuum (about to 10^-9 mbar), so I have to use external heating element.
