Description
Summary:On 1990 October 13 the Sussex Particle Correlator Experiment on the USAF/NASA Combined Release and Radiation Effects Satellite (CRRES) observed modulation in the onboard wave-particle correlation functions at frequencies between one third and one half of the electron gyrofrequency during the period from 14:45 UT to 15:45 UT. At this time the Iowa plasma wave experiment measured chorus emissions in the region of one third of the local electron gyrofrequency, and the Lockheed IMS-LO electron instrument observed an apparent velocity dispersion event in electrons between 770eV and 20 keV, beginning at about 15:12 UT. We describe the particle correlation technique, briefly present this event, and then describe an approach to testing the hypothesis that wave-particle interactions were responsible for the large modulation seen in the particle correlator. Recent work on the statistical analysis of such data is presented.
