Compact beam image reproduction transmission system

Abstract

The invention relates to a compact beam image reproduction transmission system, which comprises a first transverse focusing unit of which the input end is connected with the output end of a drift tube linear accelerator; a first buncher the input end of which is connected with the output end of the first transverse focusing unit; a first transverse deflection unit the input end of which is connected with the output end of the first buncher; a second transverse focusing unit the input end of which is connected with the output end of the first transverse deflection unit; a second transverse deflection unit the input end of which is connected with the output end of the second transverse focusing unit; a second buncher the input end of which is connected with the output end of the second transverse deflection unit; and a third transverse focusing unit connected between the second buncher and the side coupling drift tube linear accelerator. The folding function of a traditional linear accelerator can be achieved, the problem that the traditional linear accelerator is large in occupied space is solved, a design thought is provided for the field of medical linear accelerators for tumor treatment, tumor treatment equipment is smaller in occupied space, lower in cost and more convenient to operate and maintain, and popularization and development of the proton treatment technology are better facilitated.

Description

technical field [0001] The invention relates to a beam transmission system, in particular to a compact beam image reproduction transmission system, belonging to the technical field of proton therapy. Background technique [0002] Medical proton accelerators have been widely used internationally as tumor treatment equipment. Because the energy deposition of proton beams has a narrow Bragg peak effect, proton beam therapy for targeted killing of tumor cells is known as the most advanced in the world. Radiation therapy technology, compared with traditional technologies such as X-rays and electron therapy, can greatly reduce the damage to healthy tissues and organs around tumor lesions. [0003] Current proton therapy accelerators usually use proton cyclotrons, synchrotrons or linear accelerators, etc. These three accelerator technologies are relatively mature. However, due to the fixed energy of the cyclotron, the investment of additional energy reduction adjustment equipment ...
