Title: Silicon surface barrier detector application to pulsed neutron measurements

Abstract

The efficiency of a silicon surface-barrier detector with a proton radiator for detecting 14 MeV neutrons was measured as 0.29% using a polyethylene radiator, and 0.34% using a paraffin radiator. Absolute fluence and timing information can be obtained by counting the number and time distribution of pulses from the radiator/surface-barrier detector. Fluence values with an accuracy better than +- 10% could be obtained with a single 1 cm/sup 2/ detector at fluence levels greater than 3.5 x 10/sup 4/ n/cm/sup 2/, and +- 20% at fluence levels greater than 8.6 x 10/sup 3/ n/cm/sup 2/. The volume occupied by a single 1 cm/sup 2/ area surface-barrier detector could be as small as 0.1 cm/sup 3/, satisfying the requirement of miniaturization for many JTA applications.
