面向地外行星探测的脉冲中子元素分析仪
Pulsed Neutron Elemental Composition Analyzer for Extraterrestrial Planets Exploration
摘要
Abstract
In order to simulate the strata of the Moon,a miniaturized high-yield neutron generator and an integrated neutron-gamma spectrometer were designed,and an elemental analysis library and a solution method were established,a simulated well and a ground verification platform with known element content were constructed,enabling the realization of quantitative analysis for primary elements,rare elements,and other elements within the simulated lunar subsurface.The neutron generator has a yield of between 107 and 108 N/s(corresponding to pulse and DC modes,respectively),and the detection time is in the order of minutes,which can achieve an accuracy of 5%.A breakthrough in the key technology of lightweight miniaturization for neutron-gamma spectrometers in planetary exploration missions has been accomplished through this research.This achievement has established a strong foundation for future endeavors in payload space engineering.关键词
