Novel Module for Plasma Wakefield Acceleration of a Positron Beam

X. Wang, R. Ischebeck, C. Joshi, P. Muggli, and T. Katsouleas

A novel approach for studying positron acceleration physics without an external positron source is developed. This scheme uses an e- beam to both create positrons in a target before the plasma and to excite the wake that accelerates these positrons. 2-D PIC simulations show that ultra-short e+ bunches can be focused and accelerated.
