Radio frequency power source system and device for boron neutron capture therapy device

Abstract

The invention mainly discloses a radio frequency power source system for a boron neutron capture therapy device, and the system comprises a radio frequency power source module; the radio frequency power source module comprises a solid-state amplification module, a klystron power amplification module, a modulation module, a high-voltage power supply, a crowbar and a monitoring interlocking protection module. The modulator module and the crowbar are respectively connected with the high-voltage power supply; the output end of the solid-state amplification module is connected with the input end of the klystron power amplification module; the output end of the modulation module is connected with the klystron power amplification module; the signal acquisition end of the monitoring interlocking protection module is respectively connected with the klystron power amplification module, the modulation module, the high-voltage power supply and the crowbar; the signal output end of the monitoring interlocking protection module is connected with the high-voltage power supply. According to the structure of the radio frequency power source module, it is guaranteed that enough power is provided for compensating RFQ cavity consumption, the beam load effect can be compensated, and therefore, it is guaranteed that an RFQ accelerating electric field is stable; meanwhile, sufficient personal and equipment safety guarantee is provided for equipment use.

Description

technical field [0001] The invention relates to boron neutron capture therapy (AB-BNCT) equipment, in particular to a radio frequency power source system and device therein. Background technique [0002] According to statistics, there are about 3.12 million new cancer cases in China every year. Malignant tumors are the second cause of death in my country, accounting for 22.32% of the total number of deaths, while the annual number of cancer deaths in the world is as high as about 6.3 million. Hence, the development of cancer diagnosis and treatment regimens is in high demand. Existing treatment methods such as surgery, chemotherapy or common radiotherapy may cause damage or side effects to the human body. Although proton or heavy ion therapy can overcome the dose toxicity problem of conventional radiotherapy, the device cost and maintenance are expensive, the volume is large, the economy is poor, it is difficult to scale up, and the number of people treated is extremely lim...
