Re: Connecting a Pump to High Vac System

I'll be interested in anything surplus you have, Chris.

We use a lot of Alcatels at work, I think we only use the others for replacement on old units. I'll see what I can dig up.

EDIT: Maybe we still use Pfeiffers on the bigger machines.

Re: Carbon Steel

I think the ideal solution to overcome the drawbacks of carbon/alloy steel would be goldplating. (We use gold plated springs and other components in our chambers at work.)

This would also make an impressive looking chamber.

Re: FAQ - Operating a Fusor - startup - run - shutdown

Would I be correct in assuming that a smaller diff pump will be less likely to contaminate the system, due to there being less 'surface area' of oil exposed to the system?

EDIT: ie, less oil exposed to the system.

Re: Odd Plasma Formation

Thanks, Dustin.

I've learned something today.

Just trying to figure out how it fits into my 'wave' theory.

Re: Tube Lore

That is the impression I was under.

You did once suggest putting a voltage multiplier inside the chamber, though.

I just wanted to check I'd not missed something.

Thanks for the input, Doug.

Re: Tube Lore

Are you suggesting that it's possible to build a voltage multiplier using only tubes that can be used inside the chamber, Doug?
