This paper describes the design, fabrication, and initial testing of a Ka-band dielectric-loaded traveling-wave tube (TWT) with very high bandwidth. Applications for high-power mm-wave sources span radar (including imaging), biology, medicine, commun

We show experimentally that a continuous, linear, dielectric antenna in which a superluminal polarization-current distribution accelerates can be used to transmit a broadband signal that is reproduced in a comprehensible form at a chosen target dista

In the field of beam physics, two frontier topics have taken center stage due to their potential to enable new approaches to discovery in a wide swath of science. These areas are: advanced, high gradient acceleration techniques, and x-ray free electr

We are exploring the amplification of W-band electromagnetic radiation using a dielectric-loaded traveling wave tube (TWT) by employing several particle-in-cell (PIC) codes. We are seeking to replicate recent results obtained by a Naval Research Labo

We have designed a Ka-band dielectric traveling-wave tube with high bandwidth. We are currently validating the 20-kV, 5-A electron beam gun and transport system and the structure is in fabrication. We report on the design of this structure and differ

The LANL/AES normal-conducting radio-frequency injector has been tested at cw cathode gradients up to 10 MV/m. Field-emission electrons from a roughened copper cathode are accelerated to beam energy as high as 2.5 MeV and impinge on a stainless steel
