Feasibility Study of a 0.5 to 4 GeV Linac-Pulse Stretcher Electron Accelerator

摘要

Possible designs for a high energy continuous beam electron accelerator are being actively pursued by several research groups. This report is of a study of one of the alternatives; a high current pulsed linac injecting into a storage ring from which are extracted multiple continuous beams of electrons. The aim of this study was to determine whether the concept of the linac-pulse stretcher (LPS) was realistic and, if so, whether it met the requirements of the proposed physics experiments. In addition to the question of technical limitations that might exist, the following criteria were used in evaluating the design: (1) present status of accelerator concepts, (2) ease of accelerator operation, (3) flexibility of the machine, and (4) ability to upgrade the accelerator in energy, current and number of beams.
