A DETECTOR TELESCOPE WITH CHARGE-COUPLED-DEVICES FOR PARTICLE DOSIMETRY IN SPACE

A telescopic device with charge coupled devices (CCDs) for particle do simetry in space has been developed. Data on ionization events of ener getic particles passing the CCDs are processed in an image analyzing s ystem of a PC. As 'Charged Particle Telescope' (CHAPAT), the equipment was flown on the russian space station MIR during the EUROMIR mission in 1995. The response of the CCDs to various charged particles and me thods for the discrimination of heavy particles in CCDs are discussed. First results of a correlation of temporal particle fluxes to the act ual orbital parameters of MIR clearly identify passages through the So uth Atlantic Anomaly (SAA).
