Abstract：
The research is to design a differential pumping system not only to achieve the pressure transition with a large throughput, but also to achieve a clean system without back-oil. In the paper, the pressure in differential stages is calculated; the differential pumping system design and equipment choice are introduced; the tests of Molecular/Booster Pump (MBP), a new kind of molecular-drag pump with large throughout and clean vacuum are described and the system experimental result and analysis are presented.
