A Monolithic Silicon Detector Telescope

An ultrathin silicon detector (1 mu m) thick implanted on a standard 400 mu m Si-detector has been built to realize a monolithic telescope detector for simultaneous charge and energy determination of charged particles. The performances of the telescope have been tested using standard alpha sources and fragments emitted in nuclear reactions with different projectile-target colliding systems. An excellent charge resolution has been obtained for low energy (less than 5 MeV) light nuclei.
