Don't tell me you never heard of a gate valve.

The gain isn't as high and they're less reliable than a ball valve.
Higher plate current though. ;)

Oh. Forgot to add the smiley face again. Here 'tis ^^^
Sure. I'm working with one now. It lets EUV in and out.
What does a nice 4" flange-mount UHV gate valve cost, anyhow?
John
You just couldn't resist! ;)
Jamie
A couple of grand.
Smaller ones are a bit cheaper, of course.

That is rather tangled, would you try again?
??-)
Isn't the gain infinite?
lol

I thought about bringing that up, but decided it wouldn't be nice. ;-)
I've always found the CMRR are poor on them, too!
Jamie
What's tangled? Essentially most of those jobs boil down to swinging the capacitance of a Pockels cell as fast as you can in one direction. In the other direction it usually doesn't matter too much.
It's thousands of volts so you need a device that can do that. Until a couple of months ago that either meant a stack of transistors or a tube. Then Mouser started getting the IXYS high voltage FETs.
No sir, I was fixing radios in the 50s and they were grids from the time DeForest invented them.

Yup. Use them all the time for water.
Jim
Nah :-)
$16K for their biggest one.

Bruker? They do some good work.
