Title: THz-driven zero-slippage IFEL scheme for phase space manipulation

Abstract

In this paper, we describe an inverse free electron laser (IFEL) interaction driven by a near single-cycle THz pulse that is group velocity-matched to an electron bunch inside a waveguide, allowing for a sustained interaction in a magnetic undulator. We discuss the application of this guided-THz IFEL technique for compression of a relativistic electron bunch and synchronization with the external laser pulse used to generate the THz pulse via optical rectification, as well as a laser-driven THz streaking diagnostic with the potential for femtosecond scale temporal resolution. Initial measurements of the THz waveform via an electro-optic sampling based technique confirm the predicted reduction of the group velocity, using a curved parallel plate waveguide, as a function of the varying aperture size of the guide. We also present the design of a proof-of-principle experiment based on the bunch parameters available at the UCLA PEGASUS laboratory. With a $$10\,\mathrm{MV}\,{{\rm{m}}}^{-1}$$ THz peak field, our simulation model predicts compression of a $$6\,\mathrm{MeV}$$ $$100\,\mathrm{fs}$$ electron beam by nearly an order of magnitude and a significant reduction of its initial timing jitter.

Figure 1 Figure 1: Representation of the guided-THz IFEL. The electron beam executes a wiggling trajectory (in red) inside the curved parallel plate structure because of the field from the series of undulator magnets on either side of the waveguide plates. The field profile of the THz pulse, propagating in the TE01modemore » used for compression, is shown with the blue vector field.« less
