Title:
PLASMA ELECTRON-EMITTING SOURCE
Document Type and Number:
WIPO Patent Application WO/2003/081965
Kind Code:
A1
Abstract:
The invention relates to gas-discharge high-vacuum devices. Said invention makes it possible to increase the efficiency of electron beam extraction and the gas and energy efficiency. The inventive plasma electron-emitting source comprises internal and external polepieces embodied in the form of a body of rotation provided with central holes, a source of magnetomotive force arranged between said polepieces, an arc apertured hollow cathode and a gas supply unit which are arranged in a hermetically sealed body. Said source also comprises intermediate and main anodes embodied in the form of a body of rotation provided with central holes and arranged between coaxial output holes of the cathode and the body. The intermediate anode, the internal polepiece, a ring collector, the main anode and the external polepiece are arranged in series between the output holes of the cathode and the body. The main anode is made of low-magnetic material and is disposed in such a way that not less than 30 % of the magnetic flow formed in space between the polepieces passes through the hole thereof. The internal and external polepieces are electrically connected to the cathode.
