The superconducting cavity is made of superconducting materials (such as Gao Chunni). The main factors affecting the performance of the superconducting cavity are secondary electron multiplication (Multipacting), field emission, thermal runaway, etc. The main determining factors of field emission are roughness and cleanliness of the inner surface of the superconducting cavity.
In the superconducting cavity surface treatment process, main processes including Electrochemical Polishing (EP), buffer Chemical Polishing (BCP), ultrasonic cleaning (US), high-pressure ultra-pure water cleaning of an inner surface (HPR), heat treatment, optical detection, pre-tuning and the like are involved. In the process, the superconducting cavity involves a plurality of circulation procedures of entering and exiting the ultra-clean room from a conventional area (non-acid-related treatment area) and a chemical treatment area (acid-related treatment area).

It should be understood that, according to different cleaning requirements of the superconducting cavity 2, the superconducting cavity 2 can be docked to the rotary chassis 6, then a manual mode is started, the rotation parameters (rotary on/off, rotary speed of the rotary table) of the rotary table are set, and the handheld high-pressure water gun sprays and washes the key positions of the superconducting cavity.
The whole process of the cleaning process can be automatically finished after the parameters are input by the operation panel 11, and the whole cleaning process comprises the steps of cleaning agent spraying, high-pressure ultrapure water flushing and rotating the rotating chassis at a constant speed according to the set parameters. The device for automatically and high-pressure spraying and flushing the outer surface of the superconducting cavity can automatically flush the superconducting cavity 2 under no dead angle and high pressure, and is more efficient and free of manpower. In the surface treatment process of the superconducting cavity 2, the high-pressure pure water flushing can be safely, automatically and fully covered for the residues of acid liquor, greasy dirt, particulate matters and other impurities possibly existing on the outer surface of the superconducting cavity 2 and the flange opening. Particularly, the high-pressure pump equipped with the spray cleaning agent is 4bar, the angle of the spray header is adjustable, the requirement of uniformly and fully covering the spray cleaning agent to the outer surface of the superconducting cavity can be met, and the greasy dirt remained on the surface can be dissolved. The pressure of the high-pressure pump equipped with the ultra-pure water spraying can be selected according to actual demands, the angle of the spraying head is adjustable, the spraying head faces the rotating center of the superconducting cavity, and the handheld high-pressure water gun is additionally equipped, so that the residual particulate matters on the outer surface of the superconducting cavity and the residual liquid after the cleaning agent dissolves the greasy dirt can be sprayed and washed under high pressure. After the cleaning is finished, the device is provided with a hand-held air gun 23 to sweep the surface liquid, and the surface liquid is cleanly transferred to the ultra-clean room cargo shower in the dynamic ten-thousand-level clean shed through a forklift. The whole process can clean the outer surface of the superconducting cavity efficiently, safely, automatically and thoroughly.
The invention can realize automatic cleaning of different superconducting cavity types, including but not limited to superconducting cavities with frequencies of 500MHz, 650MHz, 704MHz, 1.3GHz, 1.5GHz and 3.9GHz, and can realize installation and rotation of the superconducting cavity by adding a ground pin switching tool. In addition, through suitable frock and switching, also be applicable to the surface self-cleaning of other similar articles.
It should be understood that the washing device in the prior art is low in automation degree, high in labor cost, and not integrated in the same device, for example, only a handheld high-pressure water gun is used, so that the washing effect is different due to the fact that the washing angle is changed by manual operation, and the possible washing effect is different, and even spraying of each part cannot be guaranteed. According to the device for automatically spraying and flushing the outer surface of the superconducting cavity under high pressure, the rotating mechanism rotates the cavity at a set uniform speed, the spray heads are vertically distributed to cover the maximum length of the superconducting cavity, and the spray heads are arranged above the device, so that the cleaning dead angle can be reduced to the greatest extent. After automatic spraying is finished, the device can be kept stand for about 3 minutes, so that residual liquid on the surface of the cavity is reduced, the residual liquid on the outer surface of the superconducting cavity is blown off by using a handheld nitrogen spray gun in the device, and the residual liquid on the outer surface of the superconducting cavity is reduced. If one part of the superconducting cavity is required to be cleaned in a focus manner, the handheld high-pressure water gun arranged on the device can be used for cleaning the part in a focus manner, so that the functions and effects of automation, releasing manpower, improving cleaning effect and integrating functions and performing 'fool' operation are achieved.
