| Abstract | In addition to its role in the control and management of the WEC instruments the DWP experiment runs an onboard software application - known as the particle correlator. Using data provided by the PEACE HEEA sensor via the Inter Experiment Link this application calculates the autocorrelation function of the electron count rate to investigate possible particle flux bursts on short time scales that may be indicative of regions of velocity space in which wave-particle interactions are occurring. A full description of the operation of the particle correlator may be found in the DWP Users Guide available from CAA/CSA. | ||||||

| Mission Description | Cluster is the first constellation of four scientific spacecraft to study the Earth-Sun connection in three dimensions. Cluster offers unique opportunities to investigate physical processes in near-Earth space. Those processes are essential to study and understand the effects of the Sun on the vast Earth’s environment that is a highly varying system both in time and space. The four Cluster spacecraft in a polar orbit are unique in their ability to obtain a three-dimensional picture of medium and large-scale plasma structures. The varying Cluster spacecraft formation from 3 km to a few tens of thousands kilometres along the orbit enables multi-point local measurements of different regions at different scales that cannot be done with any other space mission.
