Abstract
We have designed a silicon detector to measure the angular distributio n and the multiplicity of charged secondaries produced in high-energy Pb-Pb interactions. It will be used to characterize the events in the NA50 experiment. The experiment will have to function at very high rat e, and the silicon detectors will have to operate in the high-radiatio n area close to the target. Therefore, the detector will have to be ve ry fast (dead time below 50 ns), radiation resistant (up to the Mrad l evel as dose and up to more than 10(13) particles/cm(2) as non-ionizin g damage) and of high granularity. The conditions on noise, speed and radiation hardness are comparable to the ones foreseen at the future L arge Hadron Collider at CERN. We present here the detector design, dis cuss some of the solutions which have been investigated and report fir st results on the components of the system which have been designed an d produced up to now.
