Title High Average Current DC Photoinjector Development
Abstract A GaAs photocathode based DC electron gun has been designed to provide an average current of 100 mA by delivering bunches of charge 77 pC at 1.3 GHz. To operate at high current, the gun contains a multi-chamber photocathode preparation facility, and new photocathode structures are under development. Electrostatic calculations have been carried out to optimise the electrode design at 500 keV. Beam dynamic simulations have been carried out for transport of the beam through a 10 MeV injector line which show a final electron beam with normalised transverse emittance of less than 2.5 ·mm·mrad, longitudinal emittance of less than 10 keV·mm and a bunch length less than 2.5 ps. Further simulations show that this beam quality is achievable with a photoinjector drive laser stability of up to 1 ps.
