ON A NEW ULTRA-HIGH VACUUM PUMP,

reportActive / Technical Report | Accession Number: AD0615149 | Need Help?

Abstract:

The theory of highly rarefied cascade flow was presented and a proposal for a new axial-flow or radial flow pump or compressor in the free-molecule range was made. An unconventional cascade was suggested which will produce an extremely high compression ratio up to 30,000 in a single stage at very high blade speed S V sub bsquare root 2 RT 20. This new pump or compressor can be used to reach any ultra-high vacuum state, i.e. and almost empty state. Author
