Abstract :
A program is under way at Argonne National Laboratory, in collaboration with the Naval Research Laboratory (NRL), to develop RF-driven dielectric-loaded accelerating (DLA) structures, with the ultimate goal of demonstrating a compact, high-gradient linear accelerator based on this technology. In this paper, we report on the most recent results from a series of high power tests that are under way at NRL´s X-band Magnicon facility. The design of the latest DLA structure has been fundamentally changed from the previous generation; it now has a modular construction that separates the RF coupler from the dielectric section. In this paper we present a detailed description of the design of the new structure and of the experimental setup used during the high power tests. In addition, we will report on experimental results of high power tests carried out on an alumina-based (ε=9.4) DLA structure.
