【 摘 要 】

L-band Electron Accelerator has been widely utilized for industrial irradiation. In this paper, we designed a constant-impedance, disk-loaded structure which operates on 2π/3 mode. CST and SUPERFISH code were used for the design of bunching and accelerating cavities respectively. The geometrical parameters of the cavities were studied, and optimized RF parameters were obtained. We calculated the beam dynamics which presented that the electrons can be accelerated to 50 MeV. The model cavities have been fabricated and tested. Some valuable experimental results were obtained, which can provide a beneficial datum for the design and manufacture of L-band travelling-wave accelerating structures of 50 MeV LINAC.
