Paper Abstract

The generation and use of THz radiation for electron acceleration and manipulation of electron bunches has progressed over the last decade to a level where practical devices for THz guns, acceleration and a wide range of beam manipulations have become possible. Here, we present on our progress to generated single-cycle THz pulses at the twohundred micro- Joule level to drive advanced acceleration and beam manipulation devices. Specifically, a segmented terahertz electron accelerator and manipulator (STEAM) capable of performing multiple high-field operations on the 6D-phase-space of ultrashort electron bunches is demonstrated using these pulses. Using this device, powered by single-cycle, 0.3 THz pulses, we demonstrate record THz-acceleration of <60 keV, streaking with <10 fs resolution, focusing with <2 kT/m strength, compression to ~100 fs as well as real-time switching between these modes of operation. The STEAM device demonstrates the feasibility of THz-based electron accelerators, manipulators and diagnostic tools enabling science beyond current resolution frontiers with transformative impact.
