Time-dependent measurements of silicon-ionization dose rates inside a missile guidance system due to incident neutrons from a pulsed, white-spectrum linac source were performed. The measurements were made inside the autopilot and inside the missile guidance set for 30 deg - and 90 - deg missile orientations. Supplementary measurements were made in a simple-geometry cylinder of steel and styrofoam. The bulk-silicon-ionization dosimeter, which consisted of a silicon surface-barrier detector surrounded by silicon, was developed for these measurements. The dosimeter was calibrated for incident neutrons and gamma rays. The energy-dependent neutron calibration was converted to silicon ionization kerma for incident-neutron energies from 3 to 20 MeV. Time-dependent measurements of count rates and energy spectra of scattered neutrons and secondary gamma rays were also performed using a NE-213 detector. The energy spectrum of incident source neutrons was measured using the NE-213 detector, a /sup 6/Li glass detector, and a BF/sup 3/ detector for incident neutron energies from 0.4 eV to 20 MeV.
