Bidirectional acceleration device and bidirectional acceleration method

Abstract

The invention relates to a bidirectional acceleration device and a bidirectional acceleration method. The bidirectional acceleration device comprises a matching acceleration section and a cyclic deflection section which are connected in sequence, wherein the matching acceleration section comprises one or more than one acceleration cavity used for accelerating beam current; and the cyclic deflection section is used for carrying out deflection circulation on the beam output by the matching acceleration section and then inputting the beam into the matching acceleration section; and the beam transmission time in the cyclic deflection section is integer multiples of the beam radio frequency period time, so that the reverse beam meets the acceleration requirement of the last cavity in the matching acceleration section. According to the invention, the beam passes through the acceleration cavity in a reciprocating manner, and the beam can be accelerated in two directions, so that the cavity ofthe acceleration device can be efficiently utilized.

Description

technical field [0001] The invention relates to the technical field of accelerator applications, in particular to a bidirectional accelerator and a bidirectional acceleration method. Background technique [0002] With the development of science and technology, radioisotopes have been widely used in many fields such as industry, agriculture, medicine, environmental protection, military affairs, resource exploration, scientific research, etc., and have achieved remarkable economic and social benefits. In recent years, the annual growth rate of medical isotope consumption has been maintained at about 10%, and it is expected that there will be a large supply gap in the future. In view of its important use and supply-demand relationship, the research and production of medical isotopes is one of the hot spots in the field of nuclear technology application. [0003] Radioactive isotopes can be produced by bombarding stable nuclei with nuclear particles (such as protons, alpha part...

Problems solved by technology

In the linear acceleration device, the beam passes through the linear acceleration structure, and the utilization rate of the cavity is very low, which leads to the high cost of the linear acceleration device, and the cost is directly related to the length of the acceleration device

Due to the low utilization rate of the cavity in the linear accelerator, more cavities are needed to provide the same energy beam as the cyclotron, which not only increases the construction cost of the linear accelerator, but also increases the footprint of the accelerator
