Moderator-free neutron detection
1998 IEEE Nuclear Science Symposium Conference Record. 1998 IEEE Nuclear Science Symposium and Medical Imaging Conference (Cat. No.98CH36255), 2002Recent investigations have indicated that moderator-free thermal neutron detection may hold advantages for applications such as long-range neutron source detection and remote-handled TRU waste characterization. Moderator-free neutron detection involves the use of a directionally shielded thermal neutron detector to record only those thermal neutrons ...

This chapter concerns the detection of neutrons having thermal and epithermal energies in the range 0.0002–10 eV (20–0.1 A). Topics covered include neutron capture, neutron detection processes and electronic aspects of neutron detection. Typical detection systems and their characteristics are described.

Inorganic scintillation crystals for neutron detection
2013 3rd International Conference on Advancements in Nuclear Instrumentation, Measurement Methods and their Applications (ANIMMA), 2013Inorganic scintillators play an important role in the detection and spectroscopy of gamma and X-rays, as well as in neutrons and charged particles. For a variety of applications, new inorganic scintillation materials are being studied. New scintillation detector applications arise continuously and, consequently, the interest in the introduction of new ...

Neutron Detection via the Cherenkov Effect
IEEE Transactions on Nuclear Science, 2007We have incorporated neutron-absorbing elements in transparent, non-scintillating glasses and used the Cherenkov effect to convert neutron-induced beta-gamma radiation directly into light. Use of the Cherenkov effect requires glasses with a high index of refraction (to lower the threshold and increase the number of Cherenkov photons) and neutron ...

Since neutrons do not interact appreciably with electrons, they are always detected through effects caused by their collision with nuclei. Almost every type of nuclear interaction of neutrons results in a directly observable effect which has been used for the detection of neutrons. In the first part of the present article these various types of neutron-

Balloon-Borne Instrumentation for Neutron Detection
Review of Scientific Instruments, 1950A description is given of balloon-borne proportional counters and circuitry for telemetering and recording cosmic-ray neutron intensities. The preamplifier, amplifier, scaler, and trigger circuit described all use low drain directly heated battery-type tubes. Methods and reasons for pressurization of high voltage circuits are discussed.

Novel polysiloxane-based scintillators for neutron detection
Radiation Protection Dosimetry, 2010Polysiloxane-based scintillators are promising for employment in harsh environments, owing to their outstanding radiation resistance and thermal properties over the traditional plastics (polyvinyltoluene and polystyrene). In this work, cross-linked polydimethyl-co-diphenylsiloxane (PMPS) scintillators with 22% molar percentage of diphenylsiloxane units

Detection of solar neutrons by ground-based neutron monitors
Il Nuovo Cimento C, 1984The analysis of the Rome NM-64 data, performed on the occasion of 8 solar flares accompanied by gamma-bursts and 10 solar flares accompanied by large X-ray fluxes, shows that the solar energetic neutron events could be detected by ground-based stations particularly when they are located at mountain altitude and middle-low latitudes.
