Collinear load study for X-band linear accelerator structure

The collinear load consists of few disk-loaded cavities coated with high-resistance material on the inside walls. The load terminates the accelerator section and forms a part of actual accelerating structure with collinear to the electron beam. Not only can it dissipate residual RF power of the accelerator section in the form of skin losses, but also the particles are still accelerated in the structure. In this paper, the design and technology of an X-band constant power-loss collinear load are described in detail and some results are presented.
