ELECTRON-BEAM ACCELERATOR (ALTERNATIVES) AND METHOD FOR ELECTRON ACCELERATION Russian patent published in 2003 - IPC

FIELD: electron-beam engineering. SUBSTANCE: accelerator has vacuum chamber with electron-beam output diaphragm. Electron source is installed inside vacuum chamber. Shell encloses electron source and has first set of holes disposed on path between electron source and output diaphragm so as to ensure acceleration of electrons and shaping electron beam as they are moving from electron source through output diaphragm with potential difference being built up between shell and output diaphragm. Shell also has second and third sets of holes made on either side of electron source to ensure uniform distribution of electrons through beam section due to straightening electric field lines between electron source and output diaphragm. EFFECT: reduced space requirement of changeable electron-beam accelerating module. 25 cl, 11 dwg
