We report first operation in the terahertz regime of a cylindrical grating Smith–Purcell free-electron laser. Propagation of an annular electron beam in proximity to a cylindrical grating causes strong electron bunching due to a beam-surface wave i

We report on the development of a radio frequency (RF) linear accelerator (linac) for multiple-ion beams that is made from stacks of low cost wafers. The accelerator lattice is comprised of RF-acceleration gaps and electrostatic quadrupole focusing e

Many applications of THz radiation remain impractical or impossible due to the lack of compact sources with sufficient power. A source, in which the interaction occurs between an electron beam and a diffraction grating, has been shown in simulations
