Our group at the Laser Undulator Compact X-ray source facility (LUCX), KEK (High Energy Accelerator Research Organization) is performing experiments to generate X-rays by inverse Compton scattering. The system, to generate the X-rays requires a high intensity beam with low emittance. In this research we propose modifications to the existing system to achieve an acceleration of 200 nC in 100 bunches. Specifically, we seek to demonstrate that a new RF gun with high mode separation and high Q value will achieve a beam of good quality. A new RF power system with a modified power delivery scheme provides a good beam loading compensation with a high-intensity multi-bunch electron beam. The acceleration of 200 nC in 100 bunches with low emittance will help increase the intensity of X-rays by inverse Compton scattering.
