Abstract :
We have investigated the efficiency and the noise occupancy of a double-sided silicon strip detector, which was subjected to non-uniform proton irradiations up to a maximum equivalent fluence of 5·10 13p·cm-2. The depletion voltage, varying over time due to controlled annealing, was close to zero on one end of the 6 cm strips and 190 V at the high radiation end. We have determined the efficiency and noise occupancy on both n-side and p-side in a 106RU telescope, using a binary read-out system with 22 ns shaping time. The n-side exhibits superior performance after type inversion
