Penning discharge in electron-optical devices with an accompanying magnetic field

An analysis is made of the reasons for the onset of a Penning discharge in electron-optical devices operating at moderate and high vacuum in the presence of an accompanying magnetic field. Methods of suppressing this discharge are recommended. The main results of tests to eliminate the Penning discharge in the test rig at the Joint Institute of Nuclear Research (Dubna) and in the CERN Low Energy Antiproton Ring (LEAR) (Geneva) are presented.
