A detector telescope with charge coupled devices for particle dosimetry in space

A telescopic device with charge coupled devices (CCDs) for particle dosimetry in space has been developed. Data on ionization events of energetic particles passing the CCDs are processed in an image analyzing system 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 methods for the discrimination of heavy particles in CCDs are discussed. First results of a correlation of temporal particles fluxes to the actual orbital parameters of MIR clearly identify passages through the South Atlantic Anomaly (SAA).
