However, in space applications, the satellite is alternately in the sun-irradiated area and the shadow area, and the temperature also changes alternately. The temperature difference change in one orbital period is usually greater than 80°C. If the glass air chamber has no effective insulation measures, the glass air chamber is used as the The measuring instrument of the quantum effect generating device will not work properly

Abstract

The invention discloses a glass air chamber heat preservation device for space based on a CPT atomic magnetometer. The heat preservation device includes a main structure and a glass air chamber heat preservation sleeve, and the glass air chamber heat preservation sleeve is clamped at both ends of the glass air chamber. The glass air chamber insulation sleeve is assembled in the main structure. The present invention provides a glass air chamber insulation device for space by using polyimide material with a small thermal conductivity to make the glass air chamber insulation sleeve, and adopting the outer spline, inner "fence" and "S" section design at the same time. To ensure that when the glass air chamber is used in space, the temperature does not fluctuate greatly with the change of the orbital period.

Description

technical field [0001] The invention relates to a space-use glass gas chamber insulation device based on a CPT atomic magnetometer, and belongs to the technical field of temperature control. Background technique [0002] With the maturity of quantum technology, the application of quantum technology has gradually expanded to the field of space applications. In the current application of space quantum technology, glass gas cells are usually selected as alkali metal atomic containers and quantum effect generating devices, such as atomic clocks, atomic magnetometers (Zhangheng 01 satellite) and so on. [0003] The glass cell can only work properly within a certain temperature range. However, in space applications, the satellites are alternately in the sun-irradiated area and the shadowed area, and the temperature also changes alternately. The temperature difference in one orbital cycle is usually greater than 80 °C. The measuring instruments of the quantum effect generating de...
