| Abstract: | The article introduces a kind of combination pump suit for ultra-high vacuum system or portable instruments. In this pump, a non-evaporable getter pump(NEGP) acts as the main pumping element, leaving to a small sputter ion pump(SIP) the ancillary task of removing noble gases and methane, which are not absorbed by the NEG. The SIP is mounted in the support of the getter cartridge. This design allows achieving high pumping speed in a very small package as well as delivering interesting pumping synergies. |
