Silicon detection is a mature technology for registering the passage of charged particles. At the same time it continues to evolve toward increasing radiation tolerance as well as precision and adaptability. For these reasons it is likely to remain a critical element of detection of systems associated with extraterrestrial exploration. Silicon sensor leakage current and depletion voltage depend on the integrated fluence received by the sensor and on its thermal history during and after the irradiation process. For minimal assumptions on shielding and hence on the particle energy spectrum, and using published data on Martian ground temperature, we predict the leakage current density and the depletion voltage, as a function of time, of silicon sensors in transit to and deployed continuously on the Mars surface for a duration of up to 28 Earth-years, for several sensor geometries and a worst-case temperature scenario.

硅检测是用于记录带电粒子通过的成熟技术。同时，它继续朝着提高辐射耐受性以及精度和适应性的方向发展。由于这些原因，它很可能仍然是探测与地外探索有关的系统的关键要素。硅传感器的泄漏电流和耗尽电压取决于传感器接收的积分通量以及辐照过程中和辐照后的热历史。对于关于屏蔽以及因此的粒子能谱的最小假设，并使用有关火星地面温度的已公开数据，我们预测了硅传感器在传输到并持续部署在硅传感器上时的漏电流密度和耗尽电压随时间的变化。火星表面的持续时间长达28个地球年，
