Ulysses Anisotropy Telescopes

An energetic particle detector built within the Space and Atmospheric Physics Group at Imperial College to measure ions in the MeV energy range. This two telescope sectored instrument has 16 look directions per spacecraft spin, and particle anisotropies (the coefficients of a spherical harmonic expansion of the particle fluxes) can be calculated.

Part of the COSPIN(Cosmic Ray and Solar Particle Investigation) collaboration. The COSPIN instruments measure different types of particles across a diverse range of energies. On the right is a picture of the COSPIN box, with the two ATs telescopes visible within the yellow frame.
