Abstract
The Ulysses experimental program termed Cosmic Ray and Solar Particle Investigation (COSPIN) is described, with special attention given to the scientific objectives of the COSPIN, the measurements performed, the initial postlaunch results, and the characteristics of the individual COSPIN instruments. The instrument package of the COSPIN experiment includes the Low Energy Telescope, the High Energy Telescope, the High-Flux Telescope, the Electron Telescope, the Digital Processing Unit, two Anisotropy Telescopes, and two dc/dc power converters. Preliminary results obtained from quick-look data from COSPIN telescopes showed that the instruments are functioning properly and that their design has achieved both the wide dynamic range and the precision required in this mission.
