Abstract

This paper describes a parameter optimization of the JLC positron source design by detailed particle tracking simulations. The design parameters are modified from those of the previous JLC design study, considering the energy-density limit of the converter-target damage and the recent change in the specifications, especially the twice increase of a charge intensity of a beam pulse. It is shown that a multiple target system to share the deposition energy is inevitable and at least three targets are necessary to yield sufficient positrons within the energy-density limit.
