Simulation of 3-D effects in THz-based phase space manipulation

We simulate “zero-slippage” phase space manipulation driven by a guided THz pulse using the 3-D General Particle Tracer code and compare our results to analytical predictions for bunch compression and angular deflection. With the beam parameters available at the UCLA PEGASUS laboratory for a proof-of-concept experiment, we simulate compression by nearly a factor of 10. We compare two deflection mechanisms for transverse streaking with an emphasis on the 3-D effects introduced by the undulator field.
