ACCELERATING STRUCTURE FOR C-BAND ELECTRON LINEAR ACCELERATOR

This paper presents the results of a survey study that analyzed and compared several linear accelerator designs operating in the range of 5 to 20 MeV for use in advanced cargo inspection systems. These designs were based on klystron generated RF power input of 3.2 and 4.5 MW at 5712 MHz. Several different accelerating structures were considered including standing wave (SW) and travelling wave (TW) structures. In addition several hybrid structures, composed of a SW buncher section and TW accelerator section, were included in the study. Cells geometries and beam dynamics parameters, for these accelerating structures, were calculated using advanced numerical simulation methods. Accelerating structures and input couplers for SW and hybrid structures were designed
