INTRINSIC RESOLVING TIME OF DIAMOND NUCLEAR-RADIATION DETECTORS.

A description is given of an experimental installation for measuring the intrinsic resolving time of diamond detectors as a function of their thickness, energy resolution, bias voltage, and the type of ionizing radiation, and the results of the measurements are presented. It is concluded that the intrinsic resolving time of diamond detectors does not depend on the energy resolution, on the bias voltage in the working range 150 to 250 V, or on the thickness in the 110 to 340 mu range. For recording alpha particles being absorbed in the surface layer of a diamond detector ( approximately equals 20 mu ) and gamma quanta for which the detectors are ″thin″ the resolving time within the limits of the errors has an identical magnitude which is approximately equal to the intrinsic resolving time of the measurement path.
