Abstract

The invention discloses an electron linear accelerator with a hybrid acceleration structure. The electron linear accelerator comprises acceleration structures in two forms: a standing wave acceleration structure and a traveling wave acceleration structure; the standing wave acceleration structure is connected to the front end of the traveling wave acceleration structure; a coupling structure is arranged between the tail cavity of the standing wave acceleration structure and the head cavity of the traveling wave acceleration structure; the traveling wave acceleration structure is provided witha power feed-in port of an acceleration tube, the standing wave acceleration structure has a self-focusing function, and the traveling wave acceleration structure has the advantages of high efficiencyand no reflection, so that the accelerator does not need an isolator or an external magnetic field system, electron acceleration can be realized efficiently and compactly, and the cost of the whole machine is reduced.

Description

technical field [0001] The invention belongs to the technical field of electron linear accelerators, and in particular relates to a hybrid acceleration structure type electron linear accelerator. Background technique [0002] Electron linear accelerators are currently widely used in fields such as medical treatment, non-destructive testing, security inspection and irradiation, such as radiotherapy, industrial flaw detection, agricultural irradiation breeding, food irradiation processing, medical disinfection, etc., creating a huge economy for human daily life benefits and social benefits. [0003] At present, there are mainly two types of low-energy electron linear accelerators: traveling wave accelerators and standing wave accelerators. Among them, the traveling wave accelerator is traveling wave acceleration, and the common mode is 2π / 3 mode, which has high efficiency and stable performance. The whole machine needs to use an external focusing system, but no isolator is ne...
