Problems solved by technology

[0006] 1. The method of judging the ignition of the cavity is backward, and the reaction speed of artificial experience is slow, which cannot quickly protect the cavity;
[0007] 2. Due to the difference in personal operation proficiency and cognition, the aging effect is also different, so artificial aging is unstable;
[0008] 3. For operators, manual proficiency steps are cumbersome and highly repetitive, and it is easy to reduce work concentration due to occupational fatigue

Abstract

An embodiment of the present invention provides an automatic aging method for an accelerator resonant cavity. During the working process of the accelerator, the standing wave ratio of the power source is detected; when the detected standing wave ratio exceeds the threshold per unit time, the number of times When the threshold is exceeded, power up processing is performed; when the number of times the detected standing wave ratio exceeds the threshold per unit time is greater than the second threshold, power reduction processing is performed; when the detected standing wave ratio exceeds the threshold per unit time When the number of times is greater than or equal to the first number threshold and less than or equal to the second number threshold, the power remains unchanged. The above scheme provides a simple and effective way to achieve chamber aging, which can effectively replace the existing manual aging method, and is relatively Compared with the artificial aging method, it is more accurate and reliable, and can greatly improve the aging efficiency of the cavity and realize the efficient protection of the cavity. The embodiment of the present invention also provides an accelerator resonant cavity automatic aging device and a computer-readable storage medium.

Description

technical field [0001] The invention relates to the field of aging technology, in particular to an accelerator resonant cavity automatic aging method, device and computer-readable storage medium. Background technique [0002] Under the excitation of high-power radio-frequency microwaves, very large voltage and current will be generated inside the accelerator. In this case, there will be arc discharge when there are discontinuities on the cavity wall (such as burrs) or the vacuum inside the cavity is not good. Phenomenon, commonly known as "fire". This kind of sparking phenomenon is a common phenomenon when the cavity is just finished processing and feeding power, and from the operation of the China Spallation Neutron Source Linear Accelerator, there are also frequent sparking phenomena in the cavity that has been operated for a long time . [0003] Therefore, whether it is a newly processed cavity or a cavity that has been running for a long time, cavity aging is required ...
