Neutronics Calculations for the Common Shielding Project at ESS
V. Santoro, K. H Andersen, A. Khaplanov +5
The European Spallation Source ESS is being constructed in Lund, Sweden, to be the world's brightest cold pulsed spallation neutron source. The facility uses a 2GeV proton beam hit…
Measurements of the neutron absorption in supermirror coatings
D. D. DiJulio, V. Santoro, A. Devishvili +5
In this work we report on measurements of neutron absorption in supermirror coatings. The measurements were carried out using the SuperADAM instrument at the Institut Laue-Langevin…
Time- and energy-resolved effects in the boron-10 based Multi-Grid and helium-3 based thermal neutron detectors
A. Backis, A. Khaplanov, R. Al Jebali +33
The boron-10 based Multi-Grid detector is being developed as an alternative to helium-3 based neutron detectors. At the European Spallation Source, the detector will be used for ti…
Suppression of intrinsic neutron background in the Multi-Grid detector
E. Dian, K. Kanaki, A. Khaplanov +3
One of the key requirements for neutron scattering instruments is the Signal-to-Background ratio (SBR). This is as well a design driving requirement for many instruments at the Eur…
Software-based data acquisition and processing for neutron detectors at European Spallation Source - early experience from four detector designs
M. J. Christensen, R. Al Jebali, T. Blum +12
European Spallation Source (ESS) will deliver neutrons at high flux for use in diverse neutron scattering techniques. The neutron source facility and the scientific instruments wil…
Scattered neutron background in thermal neutron detectors
E. Dian, K. Kanaki, G. Ehlers +4
Inelastic neutron scattering instruments require very low background; therefore the proper shielding for suppressing the scattered neutron background, both from elastic and inelast…
The neutron tagging facility at Lund University
F. Messi, H. Perrey, K. Fissum +27
Over the last decades, the field of thermal neutron detection has overwhelmingly employed He-3-based technologies. The He-3 crisis together with the forthcoming establishment of th…
Multi-Grid Detector for Neutron Spectroscopy: Results Obtained on Time-of-Flight Spectrometer CNCS
M. Anastasopoulos, R. Bebb, K. Berry +23
The Multi-Grid detector technology has evolved from the proof-of-principle and characterisation stages. Here we report on the performance of the Multi-Grid detector, the MG.CNCS pr…
Characterization of Thermal Neutron Beam Monitors
F. Issa, A. Khaplanov, R. Hall-Wilton +4
Neutron beam monitors with high efficiency, low gamma sensitivity, high time and space resolution are required in neutron beam experiments to continuously diagnose the delivered be…
Neutron reflectometry on highly absorbing films and its application to 10B4C-based neutron detectors
F. Piscitelli, A. Khaplanov, A. Devishvili +7
Neutron reflectometry is a powerful tool used for studies of surfaces and interfaces. In general the absorption in the typical studied materials can be neglected and this technique…
Investigation of background in large-area neutron detectors due to alpha emission from impurities in aluminium
J. Birch, J. -C. Buffet, J. -F. Clergeau +9
Thermal neutron detector based on films of BC have been developed as an alternative to He detectors. In particular, The Multi-Grid detector concept is considered for…
Overcoming High Energy Backgrounds at Pulsed Spallation Sources
Nataliia Cherkashyna, Richard J. Hall-Wilton, Douglas D. DiJulio +18
Instrument backgrounds at neutron scattering facilities directly affect the quality and the efficiency of the scientific measurements that users perform. Part of the background at…
Neutron Position Sensitive Detectors for the ESS
Oliver Kirstein, Richard Hall-Wilton, Irina Stefanescu +17
The European Spallation Source (ESS) in Lund, Sweden will become the world's leading neutron source for the study of materials. The instruments are being selected from conceptual p…
An Information-Theoretical Approach to Image Resolution Applied to Neutron Imaging Detectors based upon Individual Discriminator Signals
Jean-François Clergeau, Matthieu Ferraton, Bruno Guérard +6
1D or 2D neutron imaging detectors with individual wire or strip readout using discriminators have the advantage of being able to treat several neutron impacts partially overlappin…
Investigation of gamma-ray sensitivity of neutron detectors based on thin converter films
Anton Khaplanov, Francesco Piscitelli, Jean-Claude Buffet +6
Currently, many detector technologies for thermal neutron detection are in development in order to lower the demand for the rare 3He gas. Gas detectors with solid thin film neutron…
