Abstract :
The SW/TW hybrid photoinjector is being developed at UCLA, INFN/LNF, and University of Rome. The hybrid gun has SW cells and TW cells in one structure. It can produce the low emittance and high peak current beam. PARMELA simulation showed the emittance and the bunch length were 2.8 mm.mrad and 0.16 mm, respectively. With the charge and frequency scaling law of the photoinjector, low charge and higher frequency case were also calculated.
