Book Description
This publication addresses recent developments in neutron generator (NG) technology. It presents information on compact instruments with high neutron yield to be used for neutron activation analysis (NAA) and prompt gamma neutron activation analysis in combination with high count rate spectrometers. Traditional NGs have been shown to be effective for applications including borehole logging, homeland security, nuclear medicine and the on-line analysis of aluminium, coal and cement. Pulsed fast thermal neutron analysis, as well as tagged and timed neutron analysis, are additional techniques which can be applied using NG. Furthermore, NG can effectively be used for elemental analysis and is also effective for analysis of hidden materials by neutron radiography. Useful guidelines for developing NG based research laboratories are also provided in this publication.

Book Description
If necessary, the instrument can be used to determine whether a given flux from a reactor is moderated or unmoderated. The experimental model contains proportional counters sensitive to fast or slow neutrons; at a tolerance flux of either, the instrument reads in the neighborhood of halfscale. The model case measures about 6 by 6 by 11 in. Power is derived from five 1.5 volt flashlight cells, and the instrument should operate continuously for more than 60 hours at room temperature. A plutonium source is used for a check of sensitivity, to ensure that the instrument is in calibration before use.

Book Description
Despite the often difficult and time-consuming effort of performing experiments with fast (14 MeV) neutrons, these neutrons can offer special insight into nucleus and other materials because of the absence of charge. 14 MeV Neutrons: Physics and Applications explores fast neutrons in basic science and applications to problems in medicine, the envir

Book Description
Silicon carbide semiconductor neutron detectors have been irradiated with 252Cf fission neutrons, thermal-neutron induced fission neutrons from 235U, and 14-MeV neutrons from a deuterium-tritium neutron generator. In the latter case, reaction peaks corresponding to 12C(n,?)9Be and 28Si(n,?)25Mg reactions have been observed. Multiple reaction branches to the 25Mg ground state and several excited states are observed for the 28Si(n, ?)25Mg reaction, and the detector energy calibration for these reactions can be derived from the peak positions. Although only the ground state branch is observed for the 12C(n,?)9Be reaction, the shift of the reaction energy with angle relative to the 14-MeV source can be used to derive an energy scale based on this reaction. These energy response measurements will form the basis for neutron spectrum unfolding methods for inferring incident neutron energy spectra from the resulting recoil-ion energy spectra in silicon carbide detectors.
