Design Study of an S-band RF Cavity of a Dual-Energy Electron LINAC for the CIS

The design of a resonance frequency (RF) cavity for the dual-energy S-band electron linear accelerator(LINAC) has been carried out for the cargo inspection system (CIS). This Standing-wave-typeRF cavity is operated at a frequency under the 2856-MHz resonance frequency and generates electronbeams of 9 MeV (high mode) and 6 MeV (low mode). The electrons are accelerated fromthe initial energy of the electron gun to the target energy (9 or 6 MeV) inside the RF cavity byusing the RF power transmitted from a 5.5-MW-class klystron. Then, electron beams with a 1-kWaverage power (both high mode and low mode) bombard an X-ray target a 2-mm spot size. Theproposed accelerating gradient was 13 MV/m, and the designed Q value was about 7100. On goingresearch on 15-MeV non-destructive inspections for military or other applications is presented.
