The PIPLS-B Mass Analyzer of Solar Wind Ions for the Interheliosond Project

The PIPLS-B ion energy mass analyzer is described for measuring and studying the ion and charge composition of the solar wind and its sources in the solar corona in the framework of the Interheliozond project. The main advantages of the device are the simultaneous registration of the mass composition of ions of selected energy, high energy resolution Δ E / E = 5%, and mass resolution M /Δ M = 60, a wide energy range from 1 to 20 keV, as well as its relatively small size and weight. A computer simulation of the electron-optical circuit of the device was carried out; the original detector assembly of the device was manufactured and tested.
