Disk-loaded waveguides for acceleration high intensity short pulse electron beams

One of the beam loading effects in linacs is limitation on the amount of number of particles that can be accelerated in very short beam pulses. The maximum number of particles is determined the correlation between the external accelerating field amplitude and the retarding field amplitude which particles radiate passing the waveguide. For increasing this value we suggested to use disk-loaded waveguides with period D that satisfies the condition: /spl lambda//2
