Abstract
The paper describes a source of electrons with a plasma emitter operat ing in a continuous-action mode. The plasma is generated in a magnetro n discharge. Electrons are collected through an opening in a plane ano de. The source generates a beam with a current of up to 1 A at an acce lerating voltage of 10-15 kV and a collection efficiency of about 100% . The high efficiency is achieved because the electrons are collected from a gas-discharge plasma through a secondary plasma generated in th e emission channel.
