Advanced Technologies for Applied Particle Accelerators and Examples of Their Use (Review)

This review presents the author’s view on modern trends in the development of charged particle accelerators for various applications, which is based on his own experience in this research field. The most promising, in the author’s opinion, areas of application of resonance accelerators are shown, in which substantial progress has been made by using new technologies. The use of high-gradient structures, novel materials, new manufacturing technologies, cooling systems, and new principles of acceleration made it possible to achieve miniaturization, to increase cost efficiency, and to succeed in adjusting accelerator parameters (to achieve variability) for industrial, medical, and research purposes, as well as for applications in security systems and quantum computers.
