Measurement Principle
High-Energy Particle instrument for ion, one of the MPPE sensors, measures the energy spectra or velocity distibutions of high-energy ions from 30 keV up to 1.5 MeV with six field-of-view directions to study plasma acceleration and transport in Mercury’s magnetosphere and coupling between magnetosphere and exosphere. It consists of a conic-shaped collimator, time-of-flight unit and microchannel plate assembly (MCP), Single-sided silicon strip Solid-State Detector (SSSD) and ASIC (SSSD-ASIC), front-end processing board, and high-voltage supply units.
