A Langmuir Probe – fluxgate magnetometer combination for Comet Interceptor

Autor: Johan De Keyser, Sylvain Ranvier, Jeroen Maes, Jordan Pawlak, Eddy Neefs, Frederik Dhooghe, Uli Auster, Bernd Chares, Niklas Edberg, Jesper Fredriksson, Walter Puccio, Pierre Henri, Olivier Le Duff, Joakim Peterson, Magnus Oja

ESA’s Comet Interceptor mission is a low budget, fast track mission to a dynamically new comet (DNC). As a DNC enters the inner solar system for the first time, it is expected to feature strong activity and to display a fluid-scale plasma environme

Space plasma spectrometers have often relied on spacecraft spin to collect three-dimensional particle velocity distributions, which simplifies the instrument design and reduces its resource budgets but limits the velocity distribution acquisition rat

Mass spectrometers that rely on microchannel plate (MCP) detectors age when they are used intensively. The ageing process is due to a reduction of the MCP gain as ions repeatedly bombard the MCP, leading to a reduction of the secondary electron yield
