ELECTRON ACCELERATOR, PATTERN MEMORY DEVICE USED FOR ELECTRON ACCELERATOR, AND CONTROL SYSTEM FOR ELECTRON ACCELERATOR

摘要

PROBLEM TO BE SOLVED: To obtain an electron accelerator capable of stably storing an electron beam even in an operation mode using an insertion light source, and to obtain a pattern memory device used for the electron accelerator and a control system for the accelerator. ;SOLUTION: This electron accelerator mainly comprises deflection electromagnets 11; converging quadrupole electromagnets 12 and diverging quadrupole electromagnets 13 installed in a linear section where a wiggler 17 is disposed; converging quadrupole electromagnets 14, 15 and diverging quadrupole electromagnets 16 installed in linear sections where no wiggler 17 is disposed. Respective excitation currents of the converging quadrupole electromagnets 12 and the diverging quadrupole electromagnets 13 installed in the linear section where the wiggler 17 is disposed are adjusted according to a magnetic field intensity generated by the wiggler 17.;COPYRIGHT: (C)2000,JPO
