Abstract

E-Driven method is a technical backup for positron source for ILC. In the positron source, the positron is generated and accelerated in a multi-bunch format with gaps in a macro pulse. We employ AM (Amplitude Modulation) to suppress the transient beam-loading, but a small fluctuation is still ex pected, depending on the compensation accuracy. In this arti cle, the positron yield which is ratio of numbers of positrons over electrons, is evaluated as a function of the compensation accuracy. With this result and the detail investigation of the beam loading compensation accuracy by AM, the positron yield of E-Driven Positron source for ILC is evaluated.
