Abstract

The invention discloses a silver film resistor-type atomic oxygen sensor, an atomic oxygen detector and application methods thereof. The silver film resistor-type atomic oxygen sensor comprises an alumina ceramic substrate, wherein a silver film resistance wire is laid on the alumina ceramic substrate; a line of the silver film resistance wire is laid on the alumina ceramic substrate in a shape like as Chinese character 'zhi'; metal electrodes are respectively arranged at two ends of the silver film resistance wire; the atomic oxygen detector comprises a precision voltage reference source, a precision resistor, the atomic oxygen sensor, an instrument amplifier and a singlechip; the instrument amplifier amplifies voltage signals at two ends of the atomic oxygen sensor and then transmits the voltage signals to the singlechip; and the singlechip is used for calculating a resistance value of the atomic oxygen sensor in real time according to the value of sampling voltage. The flux of atomic oxygen of a space can be deduced and calculated by change of a resistance value of the silver film resistance wire, and the silver film resistor-type atomic oxygen sensor and atomic oxygen detector are good in instantaneity, low in cost and high in measurement accuracy.

Description

technical field

[0001] The invention relates to the field of atomic oxygen environment in low earth orbit space and its concentration detection, in particular to a silver film resistive atomic oxygen sensor. In addition, the present invention also relates to an atomic oxygen detector comprising the above-mentioned silver film resistance atomic oxygen sensor and its application method. Background technique

[0002] Atomic oxygen is the most abundant component (accounting for about 80%) of neutral gases in low earth orbit (200-1000km), and it is also the most serious environmental factor affecting spacecraft. Atomic oxygen has strong oxidizing properties and high-speed collision energy, and has a strong eroding effect on spacecraft materials.

[0003] The research on the effect of space atomic oxygen needs to be detected with the help of equipment with excellent performance and simple structure. At present, the main measurement methods such as Kapton (polyimide) membrane mas...
