DEVELOPMENT OF LITHIUM-DRIFTED SILICON DETECTORS USING AN AUTOMATIC LITHIUM-ION DRIFT APPARATUS

Using a computer-controlled drift apparatus, we have developed lithium -ion drift techniques to produce large-size silicon detectors with a h igh success rate. Based on the improved techniques, we have made detec tors with a 115 x 25 x 2 mm3 sensitive volume. The variation of the de tector sensitivity has been shown to be homogeneous over the measureme nt area using 1150 nm infrared light.
