  • A summary of the work reported in 12 technical status and 10 technical operating reports issued on this contract is presented. Fifteen problems were studied during the course of this work of which three were active as of 28 February 1962. The general aims and accomplishments of the contract are discussed, and a survey of problems, the specific objective, and results on each are given. Problem areas included study of high energy bunched electron beams, study of frequency conversion in the low millimeter region by field emission, gas discharges, and ferrites, study of tensor media resomators using ferrites, study ofmore » coupling electron beams to Fabry-Perot resonators, study of optical pumping, study of optical frequency mixing, and study of submillimeter masers. A list of reports, conference talks, and papers along with the personnel associated with the work are included. (auth)« less
  • In this note, it is briefly discussed the accelerator design and start-to-end 3D macro particles simulation (using ELEGANT and GENESIS) of an X-band RF driven hard X-ray FEL with LCLS injector. A preliminary design and LiTrack 1D simulation studies were presented before in an older publication [1]. In numerical simulations this X-band RF driven hard X-ray FEL achieves/exceeds LCLS-like performance in a much shorter overall length of 350 m, compared with 1200 m in the LCLS case. One key feature of this design is that it may achieve a higher final beam current of 5 kA plus a uniform energymore » profile, mainly due to the employment of stronger longitudinal wake fields in the last X-band RF linac [2].« less
  • In this project we propose to investigate the use of novel accelerator structure cell geometry to enhance the performance of X-band photo-injectors. Making novel accelerator concepts possible involves fabrication and testing of components to ensure that the performance predicted by simulation is robustly achievable. This work is important because photo-injectors are increasingly used to provide high brightness electron beams for light sources, pushing their performance to the limits, but also requiring them to be user-facility stable. Careful investigation in both computer simulation and design, and low power testing of piece parts will enable the successful fabrication of an advanced X-bandmore » photo-injector.« less
  • The vacuum system of the injector for the Linac Coherent Light Source (LCLS) has been analyzed and configured by the Lawrence Livermore National Laboratory's New Technologies Engineering Division (NTED) as requested by the SLAC/LCLS program. The vacuum system layout and detailed analyses for the injector are presented in this final design report. The vacuum system was analyzed and optimized using a coupled gas load balance model of sub-volumes of the components to be evacuated.
