Title: Incidence of electron beam
Inventor: TSUMAKI KOJI
IPC: H05H7/08
Filed: 1990-01-24
Abstract: PURPOSE:To improve incidence efficiency, and to downsize a device by tuning an incidence close to a specified value, and by utilizing fourth dimensional resonance, so as to carry out the incidence of a beam. CONSTITUTION:A betatron frequency per one cycle is set close to 0.25, in an electron accumulation ring, so as to magnetize perturbator magnet including eight-pole magnetic field component. A 1/4 resonance is induced, and the incident electron is put into a stable region, in order. When the perturbator magnet is lowered as the electron is injected, the incident electron approaches a septam magnet for the first time at the fourth turn. The perturbator is weak enough at the time, and is not to be lost by bombarding to an inflector. A large bump magnet is not necessary thereby, and an incident beam can be brought inside the septam within the time the beam returns to an incidence point, whereby incident efficiency is improved and a device can be downsized.
