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.
