NAME High Rate Detector for CO
TYPE Dust Analyzer
DESCRIPTION The High Rate Detector (HRD) is part of the Cosmic Dust Analyzer (CDA) on the Cassini mission payload. The overall objective of the HRD is to carry out quantitative measurements of particle flux and mass distribution throughout the Saturn ring system. The particle impact rate and particle mass distribution will be determined with respect to Saturnian distances, distance from the rings, and to magnetospheric coordinates. The particle mass range covered by the HRD (assuming a particle impact velocity of 15 km/s) ranges from 8x10^-13 to 8x10^-8 g for differential and cumulative flux measurements, and > 8x10^-8 g for cumulative flux measurements.
