Design of a Cabinet Safe System for a portable particle accelerator: Electromagnetic optics and beam dynamics optimization. Basics, concepts and methods

As part of an accelerator based cargo inspection system, studies were made to develop a cabinet safe system by optimization of the beam optics of microwave linear accelerators working on the S-band and standing wave pi/2 mode. Measurements, modeling and simulations of the main subsystems were done and a multiple solenoidal system was designed. This cabinet safe system based on a multiple solenoidal system minimizes the radiation field generated by the low efficiency of certain microwave accelerators by optimizing the RF waveguide system and by also trapping secondaries generated in the accelerator head. The electron gun was also studied and software for its right mechanical design and for its optimization was developed as well. The multiple solenoidal system and the electron gun optimization are the backbone of a cabinet safe system that could be applied to low energy microwave electron accelerators of different manufacturers. Thus, they constitute the main topic of this book which is mainly aimed to physicists, engineers and technologists interested in particle accelerator science and technology.
