Abstract
The paper describes the design of an electron extraction device using differential pumping. An assessment of the vacuum conditions for the transition from the viscous to the molecular regime is considered, which makes it possible to confirm the correctness of the choice of the parameters of the differential pumping system, which makes it possible to confirm the correctness of the choice of the parameters of the differential pumping system. The problem of heat removal from differential pumping diaphragms in a compact all-metal body of the extraction device.
