Re: X-ray transformer modifications

I haven't had any problems with trapped air yet , but I'm also not operating it under a load or at the higher voltages it's capable of producing. There wasn't any benefit to leaving it out of oil for as long as I did. I could have easily lowered back into the oil when I wasn't working on it. That's ...

Re: X-ray transformer modifications

Hi Roberto, Unfortunately, I have not used the transformer under a load yet. I continue to "bounce" it occasionally, and have brought power up a few more times. I'm happy with the way it came out, and I expect that it will work well. If I was to do this again, the only thing I would do differently i...

Re: Vacuum General Info

Tom, this image is reported to be of an FV6-41. https://www.artisantg.com/itemimages/VG ... _View3.jpg
Being from the same series, there's a good chance this is the same on yours. Maybe comparing some of the wiring inside would help confirm that.

Re: Vacuum General Info

Vacuum General was acquired by Tylan (Tylan General), which was later acquired by Mykrolis. You might find info under the other company names. Which MFC do you need data for?

Re: New Turbopump, But what is this?

That's for sealing gas, when the pump is used in dusty or corrosive environments. See page 8 of this manual: http://www.idealvac.com/files/manualsII ... U_260A.pdf

Re: Sources for Fusor Related Items

BMI Surplus carries vacuum parts, feedthroughs, etc. http://www.bmisurplus.com/
Because they are surplus, availability and pricing changes. But, I've found some good deals there.

Re: NEG polarity on this spellman unit?

The N in the model number "RHP30N..." suggests it's setup for negative output from the factory. Unfortunately, you don't have a compete power supply there. The chassis you have is only the inverter/control unit. That heavy cable on the rear left is supposed to connect to a separate section that crea...

Re: The Beginnings of a Fusor Electrical System

I'm going to offer some thoughts on what I am seeing in your pictures, but that doesn't mean it's correct. You'll still need to test this out as discussed above. Looking at the image, I see a small coil of wire between the two yellow wires. I suspect this is an isolated power tap, maybe for a measur...

Re: Which power supply should I use

It would, but building a High Voltage transformer is non-trivial. A search on this site of the word "transformer" provided a recent thread on this topic on the first page of results. In that thread, Rich provided a couple of links you should explore if you are interested in building your own transfo...
