Description

technical field [0001] The present invention relates to the field of accelerators, and more specifically, relates to a synchrotron capable of making the output beam of the accelerator more uniform and with higher average beam intensity and an accelerator system comprising the synchrotron. Background technique [0002] Because proton beams and heavy ion beams have the characteristics of inverted depth dose distribution, small side scatter, high relative biological effect and low oxygen increase ratio, etc., making proton and heavy ion cancer treatment become the Today's international advanced and effective cancer radiation therapy. Proton beams and heavy ion beams can also simulate the radiation environment in outer space, and are effective methods for detecting aerospace single event effects and instrument radiation resistance. Protons and heavy ions can be used in the production of nuclear pore membranes for the separation of biological agents, battery separators, anti-cou...

Problems solved by technology

The slow extraction process takes a lot of time. Taking the cancer treatment device HIMM in Wuwei City, Gansu Province as an example, the slow extraction process lasts for 3s, that is, the terminal only obtains accelerated ions once within 3s, so its efficiency is low, and the average beam current The flow intensity is much smaller than that of linear accelerators and cyclotrons
