Problems solved by technology

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 CPT-atomic-magnetometer-based space glass air chamber thermal insulation device, which comprises a main body structure and glass air chamber thermal insulation sleeves clamped at two ends of a glass air chamber. The glass air chamber thermal insulation sleeves are assembled in the main body structure. According to the glass air chamber heat insulation device, the glass air chamber thermal insulation sleeves are made of polyimide materials with a small heat conduction coefficient and the outer spline, the inner fence and the S-shaped section are adopted and a e glass air chamber thermal insulation device is provided, so that when the glass air chamber is used in space, the temperature does not fluctuate greatly along with periodic changes of a track.

Description

technical field [0001] The invention relates to a thermal insulation device for a glass air chamber for space based on a CPT atomic magnetometer, which 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 chambers are usually used as alkali metal atomic containers and quantum effect generating devices, such as atomic clocks, atomic magnetometers (Zhangheng 01 satellite), etc. [0003] Glass cells work properly within a specific temperature range. 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 measure...
