A combined radial collimator and cooled beryllium filter for neutron scattering

Henrik Moodysson Rønnow, Felix Groitl

A flexible, combined, radial collimator and beryllium (Be) filter have been designed and manufactured at the Paul Scherrer Institut (PSI), Switzerland. The Be is integrated in the radial collimator by placing thin Be slices between the collimator lamellas. ...

Energy-selective neutron imaging for materials science

Steven Luc X Peetermans

Common neutron imaging techniques study the attenuation of a neutron beam penetrating a sample of interest. The recorded radiograph shows a contrast depending on traversed material and its thickness. Tomography allows separating both and obtaining 3D spati ...

CAMEA ESS - The continuous angle multi-energy analysis indirect geometry spectrometer for the European Spallation Source

Henrik Moodysson Rønnow, Paul Gregory Freeman

The CAMEA ESS neutron spectrometer is designed to achieve a high detection efficiency in the horizontal scattering plane, and to maximize the use of the long pulse European Spallation Source. It is an indirect geometry time-of-flight spectrometer that uses ...

The use of selected neutron absorption resonance filters to suppress spurious events on hot neutron spectrometers

Henrik Moodysson Rønnow, Diane Virginie Marie Lançon

Resonant absorption can be used as a filter for high energy neutron spectroscopy. Here we report the transmission of eight thin foil filters: erbium, indium, iridium, dysprosium, hafnium, gadolinium, cadmium and samarium, measured using neutron time-of-fli ...

Building and Testing a Prototype For CAMEA

CAMEA (Countinuous Angle Multiple Energy Analyser) is a new concept for analysing inelastically scattered neutrons with high efficiency. It contains many (up to 10) vertically focusing analyser arrays behind each other, analysing the scattered neutrons wit ...

Performance of ceramic anvils for high pressure neutron scattering

Livia Eleonora Bove Kado

Three kinds of ceramics, zirconia-toughened alumina (ZTA), alumina-toughened zirconia (ATZ) and yttria-stabilized zirconia (YSZ), were tested as anvil materials, mainly for the purpose of neutron scattering study under high pressure. ZTA with non-toroidal ...

CAMEA: Pyrolytic Graphite Experimental Results

The ultimate goal of the CAMEA concept is to reach a high analysing efficiency. This can be achieved in two ways. An analyser crystal with medium mosaicity will scatter neutrons with slightly different energies in different directions. Given a sample which ...

Simulation of a suite of generic long-pulse neutron instruments to optimize the time structure of the European Spallation Source

We here describe the result of simulations of 15 generic neutron instruments for the long-pulsed European Spallation Source. All instruments have been simulated for 20 different settings of the source time structure, corresponding to pulse lengths between ...

We present high-resolution triple-axis neutron scattering studies of the high-temperature superconductor La1.88Sr0.12CuO4 (Tc=27 K). The temperature dependence of the low-energy incommensurate magnetic fluctuations reveals distinctly glassy features. The g ...
