Embodiment Construction

[0026] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0027] The present invention provides a space hydrogen atom in-situ micro-detector, the micro-detector includes a shell, a protection door I2, a protection door II4, a hydrogen enrichment unit 3 and a hydrogen detection sensor 5, such as figure 1 shown.

[0028] The hydrogen enrichment unit 3 is used to store hydrogen atoms 1 and release hydrogen; hydrogen refers to hydrogen atoms or hydrogen molecules.

[0029] A temperature control element and a temperature measuring element are installed on the hydrogen detection sensor 5 to ensure that the working temperature of the hydrogen detection sensor 5 is within the range of 20°C to 50°C;

[0030] The protective door I2 closes the shell to form a space for storing hydrogen. The hydrogen enrichment unit 3 is set in the protective door I2. Hydrogen atoms 1 enter and store in the hydrogen enrichment unit 3 throug...

Abstract

The invention discloses a space hydrogen atom in-situ micro-detector and a space hydrogen atom in-situ micro-detection method. The space hydrogen atom in-situ micro-detector comprises a shell, a protection door I, a protection door II, a hydrogen enrichment unit and a hydrogen detection sensor, wherein the protection door I encloses the shell to form a hydrogen storage space, the hydrogen enrichment unit is arranged in the protection door I, hydrogen atoms enter through the protection door I and are stored in the hydrogen enrichment unit, and the hydrogen detection sensor is arranged in the shell and is isolated by the protection door II. According to the present invention, the space hydrogen atom in-situ micro-detector can be carried on a micro-nano satellite platform so as to detect theextremely low concentration hydrogen atoms, and further has advantages of high precision, low power consumption and small volume.

Description

technical field [0001] The invention relates to the technical field of detection of gas concentration, in particular to extremely low concentration (10 11 piece / m 3 ) detection of hydrogen atom concentration, used for on-orbit in-situ detection of hydrogen atom concentration in the space atmosphere environment. Background technique [0002] The abundance of H element in the space environment is 95%. The detection of H element has important academic value and scientific significance for revealing the origin of the universe, verifying the big bang theory and the cosmic redshift theory. Atomic hydrogen is the most important neutral component in the atmospheric composition of the upper space environment, and its composition changes are of great significance to the physics of the upper atmosphere and solar physics, for example, atmospheric chemistry, the coupling process of plasma and neutral particles, magnetic The energy dissipation process of the layer and the geomagnetic st...
