Abstract
S-Band standing wave (SW) linacs in the range of 1–10MeV have many potential industrial applications world wide. In order to mitigate the industrial requirement it is required to reduce the overall size and weight of the system. On this context a 2856MHz, 1MeV, bi-periodic on axis coupled self transverse focused SW linac has been designed and tested. The RF phase focusing is achieved by introducing an asymmetric field distribution in the first cell of the 1MeV linac. The pulsed electron beam of 40keV, 650mA and 5µs duration is injected from a LaB6 thermionic gun. This paper presents the structure design, beam dynamics simulation, fabrication and experimental results of the 1MeV auto-focusing SW linac.
