Particle Detectors
RAPID
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.
