| Abstract | Prototypes of Silicon Drift Detectors (SDD) have been developed in the context of the ALICE experiment R&D; program. They consist of high resolution 2D position-sensitive detectors based on the measurement of the drift time of an electron cloud produced by the passage of a particle, under the action of a constant electrostatic field. The largest prototype produced has a drift path of 35 mm which corresponds to the design value for the ALICE experiment. For a given electrostatic field, the drift velocity is very sensitive to the temperature variations. For this reason, MOS charge injectors have been implanted on the surface of the detectors in order to monitor the drift velocity during data taking. For the first time, this feature has been successfully used during test beam, leading to an optimal space resolution of 28 um. |
