Existing high-energy beam generators are typically designed for use under normal pressure and are not suitable for vacuum environments. However, to test the light output performance of a high-energy beam generator in a vacuum environment, it is necessary to collect the high-energy beam generated by the beam generator in a vacuum environment. Summary of the Invention

[0003] Existing high-energy beam collection devices are mostly designed for testing under normal pressure and are not suitable for vacuum environments. This invention aims to design a high-energy beam collection device that is suitable for vacuum environments and also has a self-cleaning function, enabling testing of high-energy beam generators in vacuum environments. This device can solve the problem of recovering beam energy during vacuum testing of high-energy beam generators. It can recover the high-energy beam energy generated during the light output capability test of the high-energy beam generator in a vacuum tank, preventing the high-energy beam from damaging the vacuum tank and the internal testing equipment.

DETAILED DESCRIPTION

[0026] The present invention will be further described below with reference to the accompanying drawings.

[0027] The high energy beam energy collection device designed in this embodiment is as follows Figure 1-6 As shown, the device consists of a cavity assembly 1, a pressure cover 2 and a glass 3, wherein the cavity assembly 1 consists of a cavity 4, a back cover 6, a front cover 5, a liquid inlet 9, a liquid outlet 10, an air inlet pipeline 12 and an air outlet pipeline 13.

[0028] The front side of the cavity 4 is open, and a front cover 5 is provided at the front opening of the cavity 4. The middle part of the front cover 5 is open, and a glass 3 is provided at the middle opening of the front cover 5. The glass 3 is pressed and fixed by the pressure cover 2.

[0029] The cavity 4 is provided with an air inlet 7 and an air outlet 8 on both sides, and both the air inlet 7 and the air outlet 8 are inclined toward the glass. An air inlet pipe 12 is installed in the air inlet 7, and an air outlet pipe 13 is installed in the air outlet 8.

[0030] like Figure 4 As shown, the back of the cavity 4 is a conical surface 11 protruding toward the front, and a back cover 6 is provided at the bottom of the conical surface 11. A back liquid flow channel is formed between the back cover 6 and the back of the conical surface 11, and a liquid inlet 9 is provided on the back cover 6.

[0031] like Figure 5 、 6As shown, the four sides of the cavity 4 are all provided with liquid flow channels, and the liquid flow channels in the four sides are S-shaped liquid flow channels. The back liquid flow channel is connected to the inlet of the lower side liquid flow channel, the outlet of the lower side liquid flow channel is connected to the inlet of the left side liquid flow channel, the outlet of the left side liquid flow channel is connected to the inlet of the upper side liquid flow channel, the outlet of the upper side liquid flow channel is connected to the inlet of the right side liquid flow channel, and the outlet of the right side liquid flow channel is provided with a liquid outlet 10. The liquid input through the liquid inlet can flow through the back liquid flow channel and the four side liquid flow channels one by one in sequence, and then flow out from the liquid outlet.

[0032] A high-energy beam passes through the glass and into the cavity assembly, irradiating the inner surface of the cavity, causing the cavity to absorb heat. Liquid nitrogen flows into the cavity flow channel from the liquid inlet and out of the liquid outlet, removing the heat from the cavity. High-pressure, room-temperature nitrogen flows in from the air inlet, directly blowing onto the inner surface of the glass, and then flows out of the air outlet, removing impurities generated within the cavity.

[0033] The inner surface of the cavity is blackened to improve the efficiency of light beam energy absorption.

[0034] The air inlet and outlet pipes, along with the interior of the cavity, form the gas flow path. The air inlet, outlet, liquid inlet, and liquid outlet components, along with the rear cover, are welded to the cavity components to form a cavity assembly. The high-energy beam collection device is constructed entirely of 2A12 material. The airtightness of the gas and liquid flow paths is tested using high-pressure gas and liquid nitrogen pressures, respectively, to ensure leakage in a vacuum environment.

[0035] The design of this embodiment adds glass with a transmittance of 99.99% to a traditional high-energy beam collection device in a normal temperature and pressure environment. A gas flow channel is added to remove excess matter generated when the high-energy beam is irradiated on the inner surface of the air cavity. The inner surface of the cavity directly irradiated by the beam is designed to be a conical surface, thereby increasing the irradiated area and improving energy absorption efficiency. The airtightness of the cavity is tested by means of liquid nitrogen and gas pressure maintenance tests to ensure that the cavity does not leak in a vacuum environment. This overcomes the shortcomings of existing technologies that cannot adapt to vacuum environments, solves the problem of recovering beam energy of a high-energy beam generator during vacuum environment testing, and ensures the safety of the test equipment.

[0036] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
