  • The purpose of this article is to simulate the performance of a neutron detector array for empirical configuration optimization and preliminary algorithm evaluation. Utilizing a compact array of borated Polyvinyl Toluene light pipes and Photomultiplier Tubes, pulse shape analysis, standard spectral histogramming, and multiplicity counting can enable neutron measurements for multiple applications. Results demonstrate that analysis with Monte Carlo N-Particle (MCNP) can be used to obtain a better understanding of field measurement results and aid in algorithm development for unfolding in conjunction with detector optimization. Use of a handheld neutron spectrometer has promise of widespread applicability. By correlating MCNP resultsmore » with empirical measurements, substantial confidence can be placed on predicting detector response to sufficiently similar spectral sources under alternate experimental configurations. In addition, use of the detector has substantial promise for operational health physics applications.« less
  • The authors performed a detailed quantitative investigation of shock-induced polarization of PVC in a wide range of dynamic pressures, the results of which are reported here. Chosen for the investigation was VNE polyvinyl chloride plastic with a density of 1.40 g/cm/sup 3/ and with the following composition, in mass%: PVC, 92.6; lead monoxide, 2.6; calcium stearate, 1.1; stearine, 0.9; and spindle oil, 2.8. The overall result of this investigation is the conclusion that there is as yet no basis for rejection of the orientational model of shock-induced polarization in polymers.
