Paper Abstract

At the Lawrence Livermore National Laboratory, a pulsed electromagnetic wiggler has been coupled to the Experimental Test Accelerator forming the Electron Laser Facility. This is a single-pass Free-Electron Laser which, because the wiggler excitation can be varied, can operate over a wide frequency range. Efficiency of conversion of electron beam to micro-wave power is 7%. This new power source is being used in a collateral program for deve-loping and testing structures suitable for a Two-Beam Accelerator. The Two-Beam Accelerator shows much promise for achieving the high average accelerating gradients, e.g., >250 MV/m, required in such next-generation electron accelerators as 1 TeV on 1 TeV linear colliders. In this paper, the results of recent tests characterizing the Free-Electron Laser are summarized. Also, progress in the fabrication and testing of key Two-Beam Accelerator hardware components are reviewed. Finally, Two-Beam Accelerator problem areas are discussed.
