inelastic scattering of Fast Neutrons from excited states in 56fe
Nuclear Physics, 2014Co-Authors: R Beyer, R Schwengner, R Hannaske, A R Junghans, R Massarczyk, M Anders, D BemmererAbstract:Abstract Inelastic scattering of Fast Neutrons from 56Fe was studied at the photoneutron source nELBE. The neutron energies were determined on the basis of a time-of-flight measurement. Gamma-ray spectra were measured with a high-purity germanium detector. The inelastic scattering cross sections deduced from the present experiment in an energy range from 0.8 to 9.6 MeV agree within 15% with earlier data and with predictions of the statistical-reaction code Talys. In addition to the γ-ray production cross sections, level cross sections for the 2 + , 4 + and 6 + yrast states in 56Fe were deduced.

neuland mrpc based detector prototypes tested with Fast Neutrons
Nuclear Instruments & Methods in Physics Research Section A-accelerators Spectrometers Detectors and Associated Equipment, 2012Co-Authors: C Caesar, T Aumann, D Bemmerer, K Boretzky, Z Elekes, D Gonzalezdiaz, J Hehner, M Heil, M Kempe, V MaroussovAbstract:Abstract Recent results from a first irradiation of multi-gap resistive plate chambers with Fast Neutrons are presented. The counters have been built at GSI and FZD. The experiment was performed at the “The Svedberg Laboratory” (TSL) in Uppsala, Sweden, utilizing a quasi-monoenergetic neutron beam with an energy E n =175 MeV. For a 2×4 gap prototype operated at E =100 kV/cm, an efficiency of (0.77 ±0.33)% was measured.

a 2d pixelated stilbene scintillator detector array for simultaneous radiography with Fast Neutrons and gammas
Journal of Instrumentation, 2021Co-Authors: Robert Adams, C Gunther, N Hoflich, O PoothAbstract:For radiography applications using Fast Neutrons simultaneously with gammas we have developed a detector with 16 stilbene crystals in a 4×4 2D array with a 5 mm pitch and a depth of 25 mm. The crystal array is read out by Silicon photomultipliers and custom signal processing electronics. The detector prototype was tested using a custom D-D Fast neutron generator at the Paul Scherrer Institute. By applying a pulse shape discrimination algorithm the detector is able to detect and distinguish Fast Neutrons and gammas simultaneously. Various attenuating samples placed between the source and detector with different materials and thicknesses were tested and the measured macroscopic Fast neutron cross sections were compared to what was expected. Deviations were studied with the help of detailed Geant4 simulations. The detection efficiency for D-D Fast Neutrons was measured to be around 10%.
