Associated Platforms CLUSTER-II Related Data Sets View all records related to this instrument Description The RAPID spectrometer for the Cluster mission is an advanced particle detector for the analysis of suprathermal plasma distributions in the energy range from 20-400 keV for electrons, 40-1500 keV (4000 keV) for hydrogen, and 10 keV/nuc - 1500 keV (4000 keV) for heavier ions. Novel detector concepts in combination with pin-hole acceptance allow the measurement of angular distributions over a range of 180ý in polar angle for either species. The detection principle for the ionic component is based on a two-dimensional analysis of the particle's velocity and energy. Electrons are identified by the well known energy-range relationship.
