    • The present invention provides a charge monitor for satellites for monitoring build up of electric charge due to charge particle fluxes impinging on the satellite. In one aspect of the invention the charge monitor includes an electrically conducting housing including at least two compartments with each compartment including a dielectric slab contained therein. An electrically conducting electrode is embedded in each dielectric slab a pre-selected distance below a top surface of the dielectric slab, the housing being mountable on a satellite with the top surface of the dielectric slab facing outwardly into space away from the satellite whereby charged particles emitted from sources external to the satellite penetrate the dielectric slab resulting in charge accumulation in each electrically conducting electrode, each electrically conducting electrode being electrically isolated from all other electrically conducting electrodes in the electrically conducting housing. The monitor includes an electrical voltage detector for sensing the floating DC voltage developed on the electrically conducting electrode in each dielectric slab, due to the charge accumulation, and converting the DC voltage into an AC voltage representative of a charge buildup on each electrically conducting electrode.
    • 本发明提供一种用于监测由于撞击在卫星上的电荷粒子通量引起的电荷的卫星的电荷监测器。 在本发明的一个方面,电荷监测器包括导电壳体,其包括至少两个隔间,每个隔室包括其中包含的电介质板。 导电电极被埋在每个电介质板中,在电介质板的顶表面下方预先选定的距离,壳体可安装在卫星上,电介质板的顶表面朝向卫星的空间,从而带电粒子 从卫星外部的源发射穿过电介质平板导致每个导电电极中的电荷累积,每个导电电极与导电壳体中的所有其它导电电极电隔离。 监视器包括电压检测器,用于感测由于电荷积累而在每个电介质板中的导电电极上产生的浮动DC电压,并将DC电压转换成表示每个导电电极上的电荷积累的AC电压。
