POWER SOURCE FOR DEFLECTION ELECTROMAGNET AND POWER SOURCE FOR ACCELERATION CORE OF CHARGED PARTICLE ACCELERATOR

摘要

PROBLEM TO BE SOLVED: To provide a charged particle accelerator which has a small and low-cost excitation power source of laptop type with about 30 cmϕ and is capable of large current acceleration.;SOLUTION: This is a power source for a deflection electromagnet for the charged particle accelerator which comprises a charged particle generating device, a deflection electromagnet, an accelerating means, and a vacuum duct. The charged particles introduced from the charged particle generating device into the vacuum duct are deflected by the deflection electromagnet, and after going through a first acceleration period and a second acceleration period, are accelerated to a prescribed energy. The power source for deflection electromagnet excites the magnetic field of the deflection electromagnet so as to be a constant value during the first acceleration period, and excites it so as to increase until the end of the second acceleration period, and the deflection electromagnet power source serves also as a switching regulator.;COPYRIGHT: (C)2005,JPO&NCIPI
