A Linear Accelerator-Injector for the SIBERIA and TNK Complexes of Special Synchrotron Radiation Sources

摘要

An 80-MeV electron linear accelerator-injector operates in a pulsed standing-wave mode. A 2.8-GHz disk-and-washer accelerating structure is composed of six 1-m-long regular sections with power input in the middle. The electron beam with parameters of 4 A/40 kV/18 ns/1 Hz from the diode gun enters the accelerating structure without prebunching. During acceleration, the beam is divided into bunches with a repetition frequency of 2.8 GHz and transported over the electron-optic channel to the booster ring. Today, the electron beam has an energy of 80 MeV, a current of 80 mA, and an energy spread of 1% and maintains continuous operation of the SIBERIA facility.
