Can you elaborate a bit on the difficulties of beam on target work? At least two people have done it. Certainly it's more substantial than a fusor.
I hope you won't landfill that chamber - I am sure that it could find much use even if not as originally intended.

Heat pipe cooling
Recently I've been messing around with heat pipes -- specifically, trying and failing to replace the water coolant charge in the standard heat pipes with acetone, which would work at much lower temperatures. (This would work better if I used, oh, I don't know, vacuum , but I would need to get cryoge...

Re: Soldering Ceramics
I've been interested in DIY ceramic to metal seals. It seems possible that with the right hacks we could make these in our own vacuum systems. Sadly, I usually haven't seen much that's really interesting/successful.

Re: Preventing Stuck Swageloks?
I really need to get a length of thin bellows hose with some Ultra Torr fittings.

Preventing Stuck Swageloks?
I have a problem with swagelok fittings, especially 1/8 inch brass swageloks on copper tubing, getting seized together -- I can unscrew the nut, but the cones on the tube don't come out of the socket. How can I fix or prevent this? Is a thin sheen of vacuum grease on the larger cone ferrule an OK id...

Re: Germanium Sputtering in the new Reserach Facility
Those spikes remind me of the tungsten field emitters formed for vacuum microelectronics (basically MEMS vacuum tubes) I use a standard KF40 manual angle valve plus a needle gas inlet valve to adjust pressure. The meaningful adjustment range for the gate valve is all pretty close to closed, but you ...

Re: Beam on Target Project (BOT 2021)
Ahhh, it's built up out of tubing pieces and machined plugs? That could simplify things...
I'm still a bit dejected over the failure of my own Penning ion source attempt -- Andrew Setzman I am not.

Re: Beam on Target Project (BOT 2021)
This is fascinating work. Makes me ashamed for mostly sitting on my behind as far as the science goes these last several months. I wish I was the equal of that machining for the ion gun -- do you have a cross section drawing of what you actually built? I have only ever seen one other beam on target ...

Re: Germanium Sputtering in the new Reserach Facility
Looks pretty cool. Probably works a lot better than my homemade experimental setup.

Re: Old oil for the turbo
Turbopumps are so fragile and expensive that I would not dare use an uncertain oil (except oil that's positively identified, but moderately expired).
