[0030] Furthermore, the numbering of the steps in the methods of this invention does not limit the execution order of the method steps. Unless otherwise specified, the method steps may be executed in different orders.

[0031] Figure 1 A schematic diagram of the windward surface structure of a detector according to an embodiment of the present invention is shown. Figure 2 A schematic diagram of a windward structure with a clamp according to an embodiment of the present invention is shown. Figure 1 and 2 As shown, the windward structure of a detector includes a reflective structure 101, a fixed structure 102, and a barrier protective layer 103.

[0032] The fixed structure 102 is used to fix the reflecting structure 101. The reflecting structure 101 and the fixed structure 102 together form a reflecting device. The barrier layer 103 and the reflecting device are disposed on the windward side of the detector, with the barrier layer 103 positioned between the reflecting device and the detector. The reflecting device is used to change the propagation direction of light particles emitted by a strong celestial body towards the detector, causing the light particles to move away from the windward side of the detector in the opposite direction to their incident direction. The reflecting device provides the first level of particle protection.

[0033] In one embodiment, the reflecting structure 101 may be, for example, an isosceles right-angled prism, which can change the direction of light propagation by 180°. The two mutually perpendicular sides of the isosceles right-angled prism are the reflecting surfaces, and the side connected to the two reflecting surfaces is the incident surface. Light particles incident on the windward side of the detector enter from the incident surface of the reflecting structure 101, undergo two reflections by the two reflecting surfaces, and move away from the windward side of the detector in the opposite direction to the incident direction.

[0034] The isosceles right-angled prism is made of high-temperature resistant quartz glass, which has an extremely small coefficient of linear expansion, only 1 / 10 to 1 / 20 that of ordinary glass, giving it excellent thermal shock resistance. High-temperature resistant quartz glass also has high heat resistance, allowing for frequent use at 1100℃-1200℃ and short-term use at 1400℃. In one embodiment, the number of isosceles right-angled prisms can be, for example, 1, 2, 3, 4, 5, 6, 7, or 8. Multiple isosceles right-angled prisms form a quasi-total internal reflection optical path system.

[0035] In one embodiment, such as Figure 1 and 2 As shown, the fixing structure 102 includes two prism support frames 1021, which serve to fix and protect the isosceles right-angle prism. The two prism support frames form a fixing structure 102 that can be used to install the isosceles right-angle prism.

[0036] The prism support frame 1021 includes a first part 1022 and a second part 1023, wherein the second part 1023 is located on the first part 1022 and the two are integrally formed. The first part 1022 has a trapezoidal cross-section, and the second part 1023 has a rectangular cross-section. The first part 1022 has a mounting surface that is inclined relative to its top. The two prism support frames 1021 are arranged opposite each other, with their mounting surfaces facing each other, forming a V-shaped mounting space. The width of the top of the first part 1022 is smaller than the width of the bottom of the second part 1023, and the second part 1023 extends inward relative to the top of the first part 1022. Here, "inward" refers to the direction toward the isosceles right-angled prism.

[0037] The installation space enclosed by the second part 1023 and the first part 1022 of the two prism support brackets 1021 is a mortise. The shape and size of the isosceles right-angled triangular prism are complementary to the shape and size of the mortise. The isosceles right-angled triangular prism is located in the mortise.

[0038] like Figure 2 As shown, the fixing structure 102 also includes clamps 1024, which are disposed on the front and rear sides of the prism support frame 1021 for fixing the isosceles right-angled prism. The clamps 1024 fix the bottom of the isosceles right-angled prism.

[0039] When installing the isosceles right-angled prism, first open the clamp 1024, then push the isosceles right-angled prism into the mortise from front to back (or from back to front), and then use the clamp 1024 to fix it in place to prevent the isosceles right-angled prism from moving back and forth. After installation, the two reflecting surfaces of the isosceles right-angled prism are respectively in close contact with the mounting surfaces of the first part 1022 of the two prism support frames 1021.

[0040] In one embodiment, the number of isosceles right-angled triangular prisms is determined by the number of isosceles right-angled prisms, for example, it can be 2, 4, 6, 8, 10, 12, 14, 16, etc.

[0041] In one embodiment, the barrier layer 103 is a rectangular composite material block that further blocks high-energy particles from entering the detector's cabin, thereby protecting the individual components inside the detector.

[0042] In one embodiment, the barrier layer 103 is made of tantalum carbide (TaC) or hafnium carbide (HfC), and the barrier layer 103 is either a tantalum carbide layer or a hafnium carbide layer. Both materials can withstand temperatures up to nearly 4000°C, especially hafnium carbide, which has set a new record in the materials science field with a melting point of 3958°C. Both materials belong to refractory ceramics and possess extremely outstanding heat resistance. These materials have been studied for use in the thermal insulation shields of next-generation hypersonic spacecraft and in the fuel cladding of nuclear reactors in ultra-high-temperature environments.

[0043] The windward structure should be combined with the sun-facing attitude to achieve optimal performance. The sun-facing attitude is defined as follows: the X-axis aligns with the vector pointing towards the center of the strongly radiating celestial body (the Sun); the Y-axis points towards the orbital plane normal; and the Z-axis points towards... To determine.

[0044] When light particles from a strongly radiating celestial body strike the windward structure, the reflective structure 101 first reflects the light particles twice, causing them to deflect by 180°. The photons and other particles then move away from the detector in the opposite direction to their incident trajectory. Figure 3A and 3B As shown. Other high-energy particles that cannot be reflected by the reflective structure 101, such as high-energy protons and cosmic ray particles, are effectively blocked by the barrier layer 103. The effectiveness of the barrier layer has been verified by simulation. The dual protection system design can effectively improve the radiation resistance of the detector.

[0045] This invention also provides a detector, which includes the aforementioned windward surface structure.

[0046] While some embodiments of this invention have been described in this application, those skilled in the art will understand that these embodiments are merely illustrative. Numerous variations, alternatives, and improvements will arise in those skilled in the art under the teachings of this invention without departing from its scope.
