SURFACE-BARRIER TELESCOPE DETECTORS

The fabrication of silicon surface-barrier telescope detectors operati ng in the total-depletion mode is described. Tee detector parameters a re listed. In order to improve the operation stability, ohmic contacts are produced by depositing a thicker aluminum layer rather than by th e transitional technique. As a result, the operating voltage is two to four times higher, the insensitive layer of the detector is minimized , and the detector can operate without failure for a long time.
