A Spatially Actively Excited X-ray Fluorescence Detector

Abstract

The invention discloses a space active excited X-ray fluorescence detector. The detector comprises a probe arranged on an inspector X panel and a moonlit survival guarantee apparatus, the probe is electrically connected to an inspector cabin comprehensive electronics plate; the moonlit survival guarantee apparatus comprises an active radiation heat source, an external support and a thermal control coating, the active radiation heat source is positioned in the thermal control coating, the thermal control coating is fixed on the inspector X panel through the external support; wherein, when the space active excited X-ray fluorescence detector is in a moonlit night state, the active radiant heat source is relative to the rear end of a probe, and provides active temperature control to the probe. The space active excited X-ray fluorescence detector has autonomous insulation capability, moon survival capability of the equipment can be greatly increased, and detection capability can be simultaneously increased.

Description

technical field [0001] The invention relates to a structure and thermal design applied to a space X fluorescence detection device, and belongs to the technical field of space detection. Background technique [0002] The high-resolution active excitation X-ray spectrometer (APXS) is one of the scientific payloads of the Chang'e-3 Yutu lunar rover and the only payload on the robotic arm. It excites elements in lunar rocks or lunar soil through the active excitation source it carries, and detects the characteristic X-rays produced by it, so as to obtain information on the types and contents of lunar elements, and provide an important basis for the study of lunar geochemical processes and formation and evolution. [0003] The spatial high-resolution active excitation X-ray spectrometer is the end of the Chang'e-3 rover's robotic arm. It is equipped with an active excitation radiation source, low power consumption, and high resolution X-ray fluorescence detection equipment. The ...

Problems solved by technology

[0013] The equipment focuses on miniaturization design, and the overall volume is small. Although the front end is made of carbon fiber material, the heat insulation effect is not ideal due to the heat capacity relationship, and due to the overly compact design, the activity and uniformity of the radioactive source are limited to a certain extent. limit, so the analytical precision is also limited

The device has no active thermal control and no on-orbit calibration design
