My mechanical pump appears to have the potiential of being a good roughing pump but will not get me down to where I need to be for anything approaching fusion and a diffusion pump is beyond my budget. Question: if using the mechanical pump for roughing, can the use of a Molecular Sieve Sorption Pump pull me into the 1 micron range or is this beyond its limits. The research tells me that it's possible for the MSS Pump to pull a 10 micron vacuum from 1 atm. and my thinking was if I could give it a head start down to about 25 microns maybe it would be capable to pull my chambers into the sweet spot.
