Reactor Update - 4/22/18

It's been several months since I was admitted to the neutron club and I'm pleased to say I have made a quite a lot of progress since then. This was the reactor when it did it's first fusion run: image.jpeg And here it is now: image.jpeg There are too many changes to count, but I'll expound on a few....

Re: Can I make my own ConFlat flanges?

Yes, it's possible to reach pressures low enough for fusion with a homemade flange. The real question is whether or not YOU Are capable of making a good enough flange. Unless you have experience with precision machining your chances of creating a usable flange are very low. You would be far better o...

Re: TMH-260 Turbo

Don’t let the pump run that long in atmosphere. Good job otherwise.

Re: Progress... or lack thereof

We're did you purchase those two big turbos? I've seen ones far smaller go for $20,000+.

Re: Operating Pfeiffer TC100 Controller

I agree, I definitely need a proper gauge, not an HVAC gauge. How do I find the pin out for this gauge? Is there a proper controller? How do I read the pressure off it?

Thanks!

Re: Operating Pfeiffer TC100 Controller

I've used McMaster-Carr many times. They are top-notch suppliers for almost everything. I will send pictures as requested within the next day. The lowest pressure with the turbo turned off is 50 microns due to the leaks. The Yellowjacket is connected to my system with Npt threads, which is connected...

Re: Operating Pfeiffer TC100 Controller

Unfortunately, living in the US usually leaves me with only npt threads. I've since purchased the correct plug. The best backing pressure I can reach is 20-30 microns. I have a Yellowjacket 69086 gauge: https://www.ebay.com/itm/Yellow-Jacket-69086-Digital-Handheld-Vacuum-Gauge/282818783842?epid=2254...
