“…Horizontally, the beam divergence was < 0.1 • . The two-dimensional position sensitive detector [35] provides a spatial resolution of 2.7 mm × 2.7 mm. As polarizing device a transportable NSF filling pressure p = 1.06 ± 0.01 bar was inserted into the neutron beam ahead of the sample and was replaced every two to three days.…”

“…According to a literature survey, the latest contributions are from German, Russian, Hungarian and American scientists concerning increasing neutron detector's sensitive area with good position resolution or high detecting efficiency, increasing the counting rate, improving the gas purity, developing curved 2D position-sensitive neutron detectors, and developing readout electronics and software modules, etc. [6,[10][11][12][13][14][15][16][17]. In addition, the recent MILAND project with most European MWPC developers was devoted to the development of a new detector with large sensitive area, high counting rate and good position resolution.…”

A two-dimensional position-sensitive neutron detector multi-wire proportional counter (MWPC) was systematically characterised on dedicated detector test station V17 at reactor BER2 of HZB. Performances including characteristic anode curve, characteristic drift curve, detection efficiency, efficiency homogeneity, horizontal position resolution, vertical position resolution, counting rate capability, and gamma sensitivity were measured. In addition, systematic simulations were conducted based on the detector configurations. These systematic studies are presented here for the first time. They assist in obtaining a greater understanding of detector performances, form the methodology for detector characterisations by reactor neutron beams, and can be used as references for neutron detector research and applications.

“…A 2-dimensional, 3 He detector (Denex GmbH) will be mounted on these motion stages, which measures the neutron location using the delay-line technique [40]. The large active area of the detector (500 mm wide £ 250 mm wide) will enable the collection of the specular reflectivity signal, off-specular scattering, as well as contributions to the background signal.…”

A time-of-flight neutron reflectometer is to be built at the new 20 MW research reactor (OPAL) in Sydney. The instrument will be positioned at the end of a curved supermirror neutron guide that will provide optimal transmission of cold neutrons (2-20 Å ) while removing fast neutrons and high-energy g-rays.The reflectometer will utilise a white neutron beam that will be pulsed using a series of boron coated disc choppers. Typically three angle settings will be required to collect a complete reflectivity profile (from Q z ¼ 0.005-0.5 Å 21 ). The new instrument will operate with a vertical scattering plane, making it suitable for both solid and "free-liquid" surfaces. The instrument will also be capable of producing a spinpolarized neutron beam making provision for polarized neutron reflectometry studies. Detection of the reflected neutrons will take place using a 2-dimensional 3 He delay-line detector with high-speed data acquisition electronics.
