The acceleration of positrons in plasma is a long-standing problem in the field of plasma wakefield acceleration. Recently, several groups have proposed novel techniques for controlling the on-axis plasma electron density in order to provide uniform accelerating and focusing fields for a trailing positron bunch [1,2,3]. In this talk, I will discuss the role of the transverse plasma electron motion in establishing useful fields for accelerating positrons in a variety of plasma geometries.
