Re: Website Update

I'm seeing something different. It appears to have just changed, as it did not look like this an hour or so ago. I've tried 2 different browsers, on 2 different computers with the same results. This is what I see, with the forum topics below it: FusorForum.jpg None of those links work either. They a...

Re: Can we have SSL?

I'm posting this in case it is helpful - I was previously logged in with http, no problem with view access. I tried https with Firefox and ran into the same problem John had. But, the issue is not a lack of trust. It's the domain name. The Cert appears to be a wildcard for the host company, rather t...

Re: High Voltage System Approval

Steven, A water pipe is not a good ground for a high voltage power supply. You can find a better ground in a nearby electrical outlet or wire. Tape is not sufficient for the connection either. Your ground cable needs to be mechanically attached to the ground, by screw pressure or something similar.

Re: Some Diffusion pump Questions

The "oddity" in your column looks like a cold trap to me. Based on the connectors, I would think the left side supports an LN2 feed, and the right side hose is the vent.

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?
