What ultimate pressure and operating pressure are you looking to achieve? What gas flow rates as well? Cryopumping definitely has the highest pumping speeds of any type of high vacuum pump, though it comes with its own unique costs and challenges. For this type of chamber, you are really limited to either diffusion or cryo, both of which require roughing before operating, though you are definitely getting to the size where cryo starts to make more sense. For any chamber though the pump has to be spec'd and sized properly for the system. If you have the infrastructure to support cryo, that can support both very clean and extremely fast pumping. I'd definitely be interested in hearing more about the pumping setup and chamber.

There will be 3 stages of pumping and a cryopump will be incorporated. We are looking for a clean vacuum operating pressure of 10^-7 torr. Certainly no diffusion pumps. Unfortunately I can't detail more on the system design, it is a challenge though given the size and surface area.

I would suggest 2-3 large Turbos and heating equipment for bakeout and RGA- right?
I'm sure you want to get a vacuum as clean as possible to reduce Bremsstrahlung from any remaining high-Z atoms.
I always dream of a vaccum chamber in a chamber where the outer chamber is filled with deuterium at ambient pressure or a little bit higher.

Werner,

Thanks for the suggestions! We are currently adapting the chamber for dual turbos, heating equipment, cryo, and it does have an RGA. I completely agree! Thanks.

Horne Technologies will also be loaning the world's first superconducting high-beta research device to the Boulder Library from 10/15 to 11/02. Come see the vacuum equipment and learn about fusion technology and superconductors!
