Problems solved by technology

Domestic detectors in the past are generally carried. Since the launch of the Chinese Academy of Sciences Space Science Pilot Project, there have been special scientific detection loads gradually. However, the materials used in the photoelectric detection unit are often hard aluminum alloys, and the quality is still relatively high.

Embodiment 1

[0058] Figure 7 to 13 A star-loaded space photoelectric conversion module, including a photoelectric conversion device 205, an electronically reading circuit board 201 (hereinafter referred to as a PCB board) and a protective structure.

[0059] The photoelectric conversion device 205 is configured to convert the flash of the crystal 109 into an optoelectronics. In this embodiment, a relatively common photomultiplier (PMT) is employed. Since it is a glass device, the space-based beam device needs to experience extremely strong mechanics. The vibration environment is required to protect the buffer 204.

[0060] The protective structure also includes an internal bushing 207, a magnetic shield device 206, an outer bushing 203, and a buffer 204, and the inner bushing 207 and the outer bushing 203 are made of a magnesium aluminum alloy material, the magnetic shielding device. 206 is a slopolo-alloy sheet, and the buffer 204 can use silicone rubber of Sylgard 170, or other similar sili...

Embodiment 2

[0076] A starboard space photoelectric detection device comprising an array of photodetecting units and a thermally conductive bracket 3. like Figure 14 to 18 As shown, the photoelectric detector unit consists of a crystal module 1 and a photoelectric conversion module 2, and the structure of the photoelectric conversion module 2 is designed with embodiment one.

[0077] The structure of the crystal module 1, such as Figure 1 to 5 As shown, components include crystalline 109, crystal protection structure, temperature detection structure, performance scalar structure, and mounting interface.

Abstract

The invention provides a space-borne photoelectric conversion module and a photoelectric detection device, the photoelectric detection device includes an array of photoelectric detection units, the photoelectric detection unit is composed of a crystal module and a photoelectric conversion module, and the photoelectric conversion module includes A photoelectric converter, an electronic readout circuit board and a protective structure. The protective structure includes an inner bushing, a magnetic shielding device and an outer bushing. Both the inner bushing and the outer bushing are made of magnesium-aluminum alloy materials. The magnetic shielding device Made of permalloy flakes. The invention makes the crystal module / photoelectric conversion module relatively independent through structural improvement, which can solve the problem of the convenience of replacing the space-borne crystal and photoelectric conversion module, is conducive to improving the inheritance of aerospace products, shortening the development cycle, and ensuring that the detection device can pass through space mechanics. The environmental assessment meets the requirements of the launch environment, and on the premise of ensuring the structural strength, the structural quality of the equipment is effectively reduced through the integrated compact design.

Description

Technical field [0001] The present invention belongs to the technical field of space exploration, space particularly, to a photoelectric conversion module spaceborne and photoelectric detection device. Background technique [0002] High-energy particle detection space, require high energy resolution and high reliability of the structure, and should have a low mass. China in the past are generally equipped with detectors, since the Space Science pilot projects start, was gradually load with a dedicated scientific exploration, but the material photoelectric detection unit partially used often or hard aluminum alloy, the quality is still large. [0003] At the same time, using satellites to carry out a special space in the sun probe is the first time our country, and the United States RHESSI satellite (using Ge detector, reference RHESSI site), Japan YOHKOH satellite (HXT using NaI) and ESA SolarOrbiter satellite (STIX using CdZnTe) different we design uses LaBr 3 Hard crystalline s...
