            <description>This document describes the Pioneer 10 
                Trapped Radiation Detector (TRD) instrument and its
                operation. Trapped Radiation Detector (TRD) data from the
                Jupiter encounter period. Using five different types of
                telescopes, the trapped radiation detector was designed
                to provide basic information about several of the 
                fundamental features of Jupiter's radiation belts including the
                types of particles within the belts, their distribution, energy, and
                intensity.</description>
