ORTEC D Series

Totally depleted silicon surface-barrier detectors for time-of-flight

Planar, totally depleted silicon surface-barrier detectors used mainly for time-of-flight measurements with heavy ions. Active areas from 10 to 450 mm² and depletion depths from 15 to 100 µm; standard detectors are cut off-axis from the parent crystal to minimise channelling. Other areas and depths on special order.

Detector type: Planar, totally depleted silicon surface barrier1
Active area: 10, 50, 150, 300 or 450 mm² (10 mm² only at 15 µm depth); larger areas on special order1
Depletion depth: Nominal 15, 25, 40, 50, 75 or 100 µm (ranges 7–15, 15.1–25, 25.1–40, 40.1–65, 65.1–85 and 85.1–110 µm)1
