Recently, considerable attention has been focused on electron beam current profile shaping by means of a transverse beam mask followed by an emittance exchanger (EEX). This setup can transform a transverse particle distribution into a longitudinal particle distribution. We investigate the EEX technique with application to production of a double triangular drive and a trapezoidal main bunches for high transformer ratio, high brightness dielectric wakefield accelerators. We perform numerical optimization of two realistic configurations: a double dogleg and a chicane. In this paper we report sample designs and discuss the effects of the beam line nonlinearities, beam space charge, and coherent synchrotron radiation on a current profile of the output beam.
