Title: High speed atomic beam generating source
Inventor: NISHIMURA TATSUYA
IPC: H05H3/02
Filed: 1992-01-21
Abstract: PURPOSE:To generate a stable neutral beam of large current with a large aperture by providing two negative electrodes and a honeycomb positive electrode between them in a generating source for generating a neutral atomic or molecular beam. CONSTITUTION:Discharge is triggered by electrons naturally generated by space beam, and the electrons are accelerated toward a positive electrode 8. However, since the positive electrode 8 has a honeycomb structure and a high void, the electrons do not get into the positive electrode 8 and reaches a negative electrode 7. Although the electrons are directed to the positive electrode 8 by receiving a repelling force from the negative electrode 7, they are passed through it, repelled by a negative electrode 6, and repeatedly reciprocated. While reciprocating between the negative electrodes 6, 7 and the positive electrode 8, the electrons collide with a gas in a discharging space to ionize the gas, and generate ions and primary electrons. The thus-formed electrons reactively form ions to continue the discharge. Thus, a stable neutral beam of large current with a large aperture can be generated with a simple constitution, and a fine work can be performed.
