The vertical frames 2 are fixedly installed on the titanium window, that is, the vertical frames 2 and the beam slot assembly 1 are fixed to the titanium window. It is necessary to avoid the vertical frames 2 and the beam slot assembly 1 blocking the titanium film. The jet assembly 3 is fixedly installed on the inner side of the vertical frame 2, and the air outlet of the jet assembly 3 faces the center and end area of ​​the titanium window, which is used to accelerate the air flow on the front side of the titanium window (around the titanium film), reduce dust suspension, reduce the contact of dust dispersed in the air with the titanium film, and adhere to the titanium film to ensure the normal radiation operation of the electron accelerator. The nozzle 407 of the spray assembly 4 is fixedly installed at the bottom of the beam slot assembly 1, and the nozzle 407 faces the titanium film, so as to spray a mist of inorganic solvent on the front side of the titanium film.

[0040] During the radiation operation, the jet assembly 3 and the liquid spray assembly 4 are controlled to work in coordination, so as to clean the titanium film installed on the titanium window, thereby effectively protecting the titanium film.

[0041] In one embodiment, the beam groove assembly 1 includes: an upper groove 105, a bottom groove 101 is opened at the bottom of the upper groove 105, a support member 102 is fixedly installed inside the bottom groove 101, and the two ends of the support member 102 are respectively provided with an end inclined portion 103 and a head inclined portion 104, and the end inclined portion 103 and the head inclined portion 104 are both lower than the middle position of the support member 102. The direct liquid supply pipe of the nozzle 407 is located in the bottom groove 101 and above the support member 102. A sliding hole 106 is opened on the side of the upper groove 105, and a manual push wheel 107 is rollingly connected to the inner side of the upper groove 105.

[0043] Another way of using is to manually clean the titanium film, that is, the user rolls the manual push wheel 107 and cooperates with the support 102 to squeeze the direct liquid supply pipe of the nozzle 407, so that the inorganic solvent remaining in the direct liquid supply pipe of the nozzle 407 flows out from the nozzle 407, which is convenient for manual cleaning of the titanium film.

[0044] Specifically, the manual push wheel 107 includes: a main roller 1071, both ends of the main roller 1071 are fixedly connected with a connecting shaft 1073, the connecting shaft 1073 is slidably connected to the sliding hole 106, the outer side of the main roller 1071 is rotatably connected with a sleeve 1072 located in the bottom groove 101, and the side of the main roller 1071 is fixedly connected with a handle 1074.

[0045] The user operates the handle 1074 to make the main roller 1071 slide inside the upper groove 105, and rotates the sleeve 1072 connected to the main roller 1071 to roll on the direct liquid supply pipe above the support 102 to squeeze the direct liquid supply pipe and drive the liquid on the direct liquid supply pipe to the nozzle 407.

[0046] In one embodiment, the liquid spraying assembly 4 includes: a spray head 407, a pump body 404 and a direct liquid supply pipe.

One end of the direct liquid supply pipe is connected to the liquid outlet end of the pump body 404, and the other end is connected to the nozzle 407. The inorganic solvent transported by the pump body 404 is sprayed out from the nozzle 407 through the direct liquid supply pipe.

[0048] Specifically, the direct liquid supply pipe includes: a first liquid supply pipe 402, a tank body 403, an adapter 401, and a branch pipe 406.
