I am on to a R & D. Looking for a few answers.

1. vacuum chamber, can it be made absolute vacuum? if so how?
2. will a mild steel chamber be goos enough? and can i paste a pice of glass for viewing the experiment in progress in chamber to the MS chamber?
3.what will be the increase in the vacuum temperature, once the chamber is vacuumed?
4. a diaphrm type vacuum pump of 25 litres a minute discharge, a good enough vacuum pump for a 40 cubic feet of chamber area?
5. do i have to reun the pump continuosly to maintain the vacuum, or once vacuum is created i shut it off?

sorry, too many questions, but basic knowledge is zero.

thanking in advance
