Abstract

The invention discloses a shaft coupling and side coupling mixed double-beam standing wave electron linear accelerator. Accelerating cavities and shaft coupling cavities are alternately connected to form a body of the double-beam standing wave electron linear accelerator, a metal short-circuit switch is arranged on a side coupling cavity, and the energy state of electron beam current is adjusted by adjusting the insertion length of the short-circuit switch into the side coupling cavity. Therefore, two energy states (high energy and low energy) of electron beam current are achieved through one standing wave electron linear accelerator, a multi-use machine is realized, and the size and cost of imaging and radiation therapy equipment are reduced.

Description

technical field [0001] The invention belongs to the technical field of standing wave electron linear accelerators, and more specifically relates to a dual-beam standing wave electron linear accelerator of a mixed axial coupling and side coupling type. Background technique [0002] Standing wave electron linac is the most rapidly developed type of electron linac in the field of accelerators. Compared with other types of electron linac, standing wave electron linac has the advantages of small size, strong acceleration gradient, high acceleration efficiency, and electron beam current. In recent years, it has extensive research and development in the field of medical radiation therapy. [0003] At present, in the field of medical radiation, since the energy of the electron beam used for imaging and radiotherapy is not the same, two sets of independent electron linear accelerator systems are often used for the positioning of patient parts and radiotherapy, because the coordinates...
