Characterization of the IRSN neutron multisphere spectrometer (HERMEIS) at European standard calibration fields
The Institute for Radiological Protection and Nuclear Safety (IRSN) has developed a new spectrometry system for neutron energies from 10−9 MeV to 10 GeV. This high energy range multisphere extended IRSN system (HERMEIS) is a high gas pressure3He-based Bonner spheres set. It is adapted to low neutron fluence rate measurements and one of its main application concerns the determination of cosmic-r...
متن کاملCompton scattering as a probe for materials investigation
This article investigates into the feasibility of using gamma radiation Compton backscatter spectra as a means of material characterization, with the view to developing a portable, hand held probe for investigative purposes such as searching for illicit substances hidden in wall or car door cavities.
متن کاملAdapting a triple-axis spectrometer for small angle neutron scattering measurements.
Small angle neutron scattering (SANS) instruments typically cover a q (scattering vector) range from 0.001 to 0.6 A(-1). This range in q is achieved through a combination of cold neutrons (lambda>4 A) and a highly collimated beam. However, as a direct result of the unavailability of a cold source at the Canadian Neutron Beam Centre (CNBC), we have resorted to adapting a triple-axis spectrometer...
متن کاملThe Disk Chopper Spectrometer at NIST: a new instrument for quasielastic neutron scattering studies
We describe the Disk Chopper Spectrometer (DCS) at the NIST Center for Neutron Research (NCNR). The maximum measured flux at the sample, averaged over the 3 cm width and 10 cm height of the beam, with all choppers turning at 20,000 revolutions per minute and phased to transmit neutrons through the widest slots on each disk, is approximately 3 10 n cm 2 s . In this configuration the elastic reso...
متن کاملNIST Calibration of a Neutron Spectrometer ROSPEC
A neutron spectrometer was acquired for use in the measurement of National Institute of Standards and Technology neutron fields. The spectrometer included options for the measurement of low and high energy neutrons, for a total measurement range from 0.01 eV up to 17 MeV. The spectrometer was evaluated in calibration fields and was used to determine the neutron spectrum of an Americium-Berylliu...
