| 摘 要： | 月尘粒子在月表高真空、高低温交变、强辐射条件下极易带电悬浮,大量带电月尘会聚集在探测器表面造成极大危害。为了能够更好地了解月球尘埃的带电特性,对月尘带电特性进行了分析,提出一种测量方法,设计出一种能够测量带电月尘荷质比的传感器,并设计出地面检测和标定实验方法,为将来探月工程中原位监测月尘带电粒子荷质比提供了很好的技术支持。

| Abstract: | The lunar environment comprises a high vacuum, high and low temperature changed, and high radiation. This environment provides lunar dust get charged, lunar dust will accumulate on the surfaces of detector, and this may cause hazards for future exploration missions. To better understand the physics of lunar dust particles is essential to future moon missions. We research and design a sensor, charge/mass sensor to detect the charge distribution and mass distribution of lunar charged dust particles. The sensor will be tested and calibrated for simulated lunar condition in our later work. |
