Description
A new S-band photocathode RF gun proposed for ultrafast electron diffraction (UED) has been designed and optimized. The electron gun works at pi mode and the operating frequency is 2.998GHz. The pulsed RF power loss is 3.2MW and the final kinetic energy of the electron beam is 3.5MeV. The RF gun works at high duty factor of 0.2% and the average power loss reaches 6kW. We have used ASTRA, a space charge tracking algorithm to simulate the beam dynamics and improve the bunch properties. By comparing the simulation results under different conditions, we found that the electron beam has good properties both transversely and longitudinally under some conditions. The simulation of bunch properties helps improve spatial-temporal resolution of UED.
