Powering a Photogun using Single-Cycle Terahertz

Abstract

Development of THz-powered photoguns promises to bring benefits to many applications by scaling down the size and cost of these devices as well as creating new capabilities. In particular, THz photoguns producing MeV beams are desired as the front end for THz-powered LINACs. Generating sufficient THz energy, however, is challenging, as is transporting and coupling the THz into the gun. We present initial results on development of the THz source and transport for an MeV gun.
