Abstract: An ultra-high vacuum (UHV) system includes a UHV cell and an ion pump to maintain the UHV in the UHV cell. The ion pump has a GCC (glass, ceramic, or crystalline) housing. An interior wall of the ion-pump housing serves as an anode or bears a coating that serves as an anode. At least one cathode is disposed with respect to the housing so that it can cooperate with the anode to form an electric field for establishing a Penning trap. The GCC housing defines a flow channel that extends radially through the anode so that a molecule can flow directly into the most ionizing region of a Penning trap.

Abstract: A small-sized charged particle beam apparatus capable of maintaining high vacuum even during emission of an electron beam is provided. A nonevaporative getter pump is placed upstream of differential pumping of an electron optical system of the charged particle beam apparatus, and a minimum number of ion pumps are placed downstream, so that both the pumps are used in combination. Further, by mounting a detachable coil on an electron gun part, the inside of a column can be maintained under high vacuum with a degree of vacuum in the order of 10−8 Pa.
