Novel Technologies for Compact Electron Linear Accelerators (Review)

This paper reviews new technologies that make it possible to implement such modern principles of development and creation of applied linear electron accelerators as modularity, miniaturization, and cost reduction. The development of accelerators in this direction became possible due to the emergence of technologies such as compact sources of radio-frequency (RF) power supply and efficient approaches to the fabrication of accelerating structures, as well as an increase in accelerating gradients and a decrease in the power of RF losses in structures. The review is based on the author’s experience in developing compact accelerators.
