Abstract
A system and method for injecting an electron beam to an accelerator are provided. The system may include a cathode, an anode, and a modulation electrode. The cathode, for generating the electron beam, may have a first electrical potential. The anode may have a second electrical potential. The modulation electrode, located between the cathode and the anode, may be configured to adjust at least one parameter of the electron beam. The at least one parameter of the electron beam may include at least one transverse parameter of the electron beam.
