Electron Recirculation through different Cusps revisited

[D Tibbets]

You have to be very careful in choosing the aluminum alloy. Some of them (most of them?) are prone to serious outgassing.

Don't ask me to defind my arguement, but on the Bell Jar forum ( a bunch of vacuum enthusiasts) there was a ranking of various metals for outgassing concerns. Stainless steel was best , then aluminum (which alloy?), then soft iron.

Of course you also have to worry about sputtering vunerability, hydrogen (deuterium) embritalment, etc.

You're worried about a little Al outgassing, with the amount of He that is [supposedy] going to need extraction, and all the sputtering??!!

Do you not think you're confusing your visions of a nice little lab experiment that struggles to get any detectable nuclear reactions going, as compared with the fire-breathing MW reactor you're dreaming of??

The previous comment nailed it: You will need low sputtering materials far far more than worrying about trivial amounts of outgassing!!!!

It's like listening to someone worrying that they don't have the right kind of water-resistant watch, in the event of a tsunami! Yeah, you could argue it might be important..... but you've not really grasped the reality of the situation!

Chris,

Outgassing prevents getting the desired level of vacuum in the system.

BTW are you having a bad year? Your significant other leave you? The Dreary English winters getting you down?
