Pumps, Vacuum Parts, 1 uF 2 kV caps, and Molybdenum for Sale

Greetings, I have a few small things that I'd be willing to sell. I'm planning on taking them over to eBay later, but I wanted to give you guys first-dibs and a good deal. I am willing to negotiate on ALL prices based on your needs and situation. I'm open to all offers. Enjoy! Two-stage 5 CFM mechan...

Re: NW16/25 (KF16/25) to CF275 Adapter

Good news! Andrew Seltzman sold me a KF16 to CF275 adapter for a mere $45 and $8 universal US shipping. If anyone else is interested in one of these adapters for the same price, he still has one left over that he is looking to sell, along with some other cool things on his eBay page: https://www.eba...

NW16/25 (KF16/25) to CF275 Adapter

I was curious if anyone would happen to have any NW(KF) 16 (or NW/KF25) to CF275 adapters that they might be willing to sell. Unfortunately, it looks like LDS and eBay are charging over $70 for this piece. Likewise, I was hoping that someone on the forum might be willing to sell a similar piece for ...

Re: Reliable Mechanical Pump for Fusion

Great development! I was talking with Torr Industries and they offered to lend me a 10 CFM 15 mTorr mechanical pump (a DV-285N Platinum) for my system. I really must say that these guys, particularly Mike Droney, are some of the best guys you'll come across when dealing with vacuum components. I' go...

Reliable Mechanical Pump for Fusion

Greetings, I was curious if someone had (or knew of) a reliable mechanical pump that would be usable for establishing a 10^-5 torr (minimum of 10^-4 torr) vacuum for fusion. Unfortunately, I'm in a bit of a rush with the shipping of items, as I have a final deadline of this Monday (March 3rd) to get...

Greetings,

I'm in need of capacitors that can handle high voltages (at least 2 kV) and current up to 800 A for 2 uS.

If you have capacitors that fit these specs, please email me at guertlerj21@barringtonschools.org or PM me on the forum. Thank you.

Re: 1 uF 1kV Ceramic Capacitors

Oh boy, looks like I've struck gold! Beats Mouser, usually have a 26 week to 6 month FACTORY lead time, not including what it takes for processing the order and getting it shipped out. Fortunately, I was able to find a set of smaller 0.01 uF ceramic caps. The pulse width with these caps will only be...
