Abstract

The invention belongs to the technical field of electron accelerators, and particularly relates to an electron linear accelerator, in particular to an energy-adjustable electron linear accelerator. The electron linear accelerator comprises the adjustable power divider, an output port of the power divider is connected with two electron linear accelerating tubes respectively, the piston short-circuit surface of the adjustable power divider is connected with a stepping motor, and the stepping motor adjusts the position of the short-circuit piston to change reflection microwave phases borne by the two output ends of the power divider, so that the energy of electron beams output by the accelerators connected to the two ends is changed. The microwave power source can be effectively prevented from shaking in the energy adjusting process, and the assembly size and weight of the device are greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of electron accelerators, in particular to an electron linear accelerator, in particular to an electron linear accelerator with adjustable energy. Background technique [0002] Electron linear accelerators with adjustable energy have an extremely urgent need for expansion in the field of image-guided radiotherapy. Due to the different biological effects of electron beams with different energy levels on human tissue cells, people can achieve different purposes such as imaging of human tissue or radiotherapy. Usually, low-energy electron beams generate low-dose X-rays by shooting targets to treat patients. Imaging, while high-energy electron beams generate high-dose X-rays through targeting or directly irradiate the patient for radiation therapy. Due to the inevitable breathing and other physiological movements of the patient during the treatment, the position of the lesion will change. Therefore, frequent an...
