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

[0060] like Figure 1 to Figure 5 A crystal module shown in a space-borne photoelectric detection unit includes crystal 109, a crystal protection structure, a temperature detection structure, a performance calibration structure, and an installation interface.

[0061] The crystal protection structure includes a shell 101, an end cap 103 and a quartz glass sheet 106. In this embodiment, the shell 101 and the end cap 103 are made of aluminum. In order to further reduce the structural quality, a magnesium alloy may be considered.

[0062] The tube shell 101 has a T-shaped shape, the upper part is a head, which is connected with the photoelectric conversion module, and is in the shape of a rectangular block, and the lower part is a cylindrical tube body, and the head and the tube body are integrally formed. The shell 101 is provided with a cylindrical body cavity, and the crystal 103 is installed in the body cavity.

[0063] The end cap 103 is composed of an integrally formed cov...

Embodiment 2

[0077] like Figure 14 to Figure 17 A space-borne photoelectric detection unit shown includes a crystal module 1 and a photoelectric conversion module 2 . The structural design of the crystal module 1 is the same as that in Embodiment 1, and the structure of the photoelectric conversion module 2 is as follows Figure 7 to Figure 13 As shown, it includes a photoelectric conversion device 205, an electronic readout circuit board 201 (hereinafter referred to as a PCB board) and a protective structure.

[0078] The photoelectric conversion device 205 is used to convert the flash light emitted by the crystal 109 into photoelectrons. In this embodiment, a more commonly used photomultiplier tube (PMT) is used. Since it is a glass device, the space-borne device needs to experience extremely strong mechanical forces. Vibration environment, so buffer glue 204 is needed to protect it.

[0079] The protective structure also includes an inner bushing 207, a magnetic shielding device 206,...

Abstract

The invention provides a crystal module and a space-borne space photoelectric detection unit containing the crystal module, the photoelectric detection unit includes a crystal module and a photoelectric conversion module, and the crystal module includes a crystal, a crystal protection structure, a temperature detection structure and Performance calibration structure and other components, the photoelectric conversion module includes components such as photoelectric conversion devices, electronic readout circuit boards and protective structures. The invention makes the crystal module and the photoelectric conversion module relatively independent through structural improvement, which can solve the problem of the convenience of replacing the spaceborne crystal and the photoelectric conversion module, is beneficial to improve the inheritance of aerospace products, shorten the development cycle, and ensure 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 invention belongs to the technical field of space detection, and in particular relates to a crystal module for space detection and a photoelectric detection unit based on the crystal module. Background technique [0002] To detect high-energy particles in space, a structure with high energy resolution and high reliability is required, and it should have a small mass. Domestic detectors in the past are generally carried. Since the launch of the space science pilot project of the Chinese Academy of Sciences, special scientific detection loads have gradually been available. However, the materials used in the photoelectric detection unit are often hard aluminum alloys, and the quality is still relatively high. [0003] At the same time, it is the first time in my country to use satellites to specialize in space sun detection, which is different from the American RHESSI satellite (using Ge detector, reference RHESSI website), Japan's YOHKOH satellite (H...
