Re: Usable X-ray Transformer?

To be sure you would need to get the model number and find the user manual. With something that old it may not be online though.

Re: Usable X-ray Transformer?

The xrt is inside the part hanging off of the swivel arm.
Looks similar to the one I got. Should be large/old enough.

Cryocooler

Got a cryocooler unit at an auction for $140. Does anyone have a guess as to the manufacture? It came with turbo pump controller but the only number on the controller is MR0808Y029, which I can't find any info on. It didn't come with the Turbo pump so I'm not sure which brand of pump it's suppose to...

Re: Second Opinion on XRT

That is very large XRT, and can supply plenty of power. Maybe too much considering the price and if you don't plan on using it for more then a fusor. Finding older XRT applies more to dental XRT, since the newer ones tend to be smaller. A dentist was selling a XRT on craigslist as scrap metal, I wen...

Re: Capillary tubing & connectors for chromatography for D2?

It looks like a gas chromatography column, but not sure why it would be flattened.

Re: Reusability of Swagelok

Ferrules aren't meant to be removed and re-crimped on a new tube. If you manged to get one of it would probable be too deformed to get back on a new tube.
At work I reuse the nuts all the time, just cut of a section of the tube and add new ferrules.

Re: The Beginnings of a Fusor Electrical System

It looks to me that the two primary's are meant to always be in parallel. Putting primary's in parallel is done to increase the current that can be transferred to the secondary not to increase the voltage at the secondary. I agree with Richard about the 120/220V based of the resistance difference be...

Re: High Voltage Supply for PMT

I think it's an 'economy of scales issue' where it's not really worth it for distributors like Mouser and Newark to sell CCFL transformers anymore. Especially with LED's taking over. You'll likely need to buy straight from the manufacture. CTX210609-R is obsolete but there may be other similar parts...
