THE DESIGN AND SIMULATION STUDIES OF THE PRE-INJECTOR FOR CANDLE LIGHT SOURCE

In this report the design layout and simulation study of the pre-injector for CANDLE project are presented. The pre-injector design includes the thermionic gun and the bunch formation systems. The gun is the standard triode gun, modulated by 500 MHz amplifier, which matches the beam pulse structure to the booster and storage ring RF buckets. The downstream 500 MHz and 1 GHz subharmonic bunching cavities perform an additional subbunching of the beam which will be accelerated in the 100 MeV S-Band injector linac. The single and multi bunch modes of the pre-injector operation are considered. The simulations are performed using PARMELA and E-Gun codes.
