Presentation Development of Active Space Radiation Detector, A-DREAMS-2 at NIRS

Uchihori, Yukio  ,  Kodaira, Satoshi  ,  Kitamura, Hisashi

For real time radiation monitoring in space environment, active radiation dosimeters, A-DREAMS have been developed in NIRS. They have silicon semi-conductor detectors and electric circuits to obtain LET distribution of space radiation from protons to iron ions in space radiation. The 1st version of the active dosimeter is named A-DREAMS-1 and has one silicon semi-conductor detector. The A-DREAMS-1 has been operated in some experiments in ground-based accelerators, HIMAC and a cyclotron facilities in NIRS and irradiated to high energy protons and heavy ions. The obtained results show good linearity for deposit energies in the silicon detector.
