“…A chopper is a device that can select or omit different parts of a charged particle beam. The most common types for the fast choppers are pulsed deflecting plates and RF resonating cavities [6][7][8][9]. The designed chopper for the ILSF pre-injection system is displayed schematically in figure 2.…”

In this paper, the design proposal for the Iranian Light Source Facility (ILSF) chopper is presented and the expected performance of both single bunch and multi-bunch modes of beam injection into the booster synchrotron is described. For the multi-bunch mode, a 100 MHz sub-harmonic pre-buncher is proposed to be employed next to the electron gun particularly to reduce the particle loss during the energy ramp of the booster. The results indicated significant improvement of the injection efficiency into the booster. The total particle loss rate for the multi-bunch injection is reduced from 35% to 4%.

A 120 MeV, 2856 MHz, TW linac, with a microwave gun, alpha magnet, and chopper, has been built at SSRL as a preinjector for and along with a 3 GeV booster syn chrotron ring. The resulting injector will be available on demand to fill SPEAR, which is a storage ring now dedi cated to synchrotron light production. The linac sections were purchased from China, the XK-5 klystrons were ob tained surplus from SLAC, the modulators are a varia tion on those at SLAC and were built by SSRL, the alpha magnet and chopper were designed and built at SSRL and the microwave gun was designed and built in collaboration with Varian Associates. The RF system for the booster ring is similar to those at SPEAR and PEP and was built by SSRL. Some of the interesting mechanical and electri cal details are discussed and the operating characteristics of the linac and ring RF system are highlighted.
