Abstract: The use of THz radiation for electron acceleration and manipulation of electron bunches has progressed over the last decade to a level where practical implementations of THz-powered photoguns, LINACs and a wide range of beam manipulators have become possible. Here, we present a segmented terahertz electron accelerator and manipulator (STEAM) capable of performing multiple high-field operations on the 6D -phase-space of ultrashort electron bunches. With this single device, powered by few-micro-Joule, single-cycle, 0.3 THz pulses, we demonstrate record THz-acceleration of >30keV , streaking with <10 fs resolution, focusing with >2kT/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.
