Abstract The aim of this work is to describe the development and implementation of an experimental setup able to reproduce some characteristics of the Martian atmosphere. The development of such setup fits into the context of MicroMED project, that foresees the development of an optical particle counter to be accommodated on the ExoMars 2020 Surface Platform, as part of the suite of sensors named Dust Complex. MicroMED will perform the first direct measurement of the size distribution of the powder close to Martian surface. The experimental setup is able to reproduce the characteristics of the Martian atmosphere: pressure, atmospheric composition, the actual temperature in which MicroMED will operate (from −20 °C to 40 °C) and the most important thing: the presence of suspended dust. The main result obtained in this work was the right configuration of an experimental setup in which to test sensors or instruments that work in Martian conditions. In particular, a dust injection system has been developed in order to obtain a dust distribution that was localized and without the formation of particles aggregates, for a correct calibration of the instrument.

火星环境室：灰尘系统注入

摘要 这项工作的目的是描述能够重现火星大气某些特征的实验装置的开发和实施。这种设置的开发符合 MicroMED 项目的背景，该项目预计将开发用于 ExoMars 2020 表面平台的光学粒子计数器，作为名为 Dust Complex 的传感器套件的一部分。MicroMED 将首次直接测量靠近火星表面的粉末的粒度分布。实验装置能够重现火星大气的特征：压力、大气成分、MicroMED 运行的实际温度（从 -20 °C 到 40 °C）以及最重要的事情：悬浮灰尘的存在。在这项工作中获得的主要结果是实验装置的正确配置，用于测试在火星条件下工作的传感器或仪器。特别地，已经开发了粉尘喷射系统以获得局部且不形成颗粒聚集体的粉尘分布，用于仪器的正确校准。
