The development of sensors capable detecting particles and radiation with both high time positional resolution is key to improving our understanding in many areas science. Example applications such range from fundamental scattering studies chemical reaction mechanisms through imaging mass spectrometry surfaces, neutron aimed at probing the structure materials, time-resolved fluorescence measurements elucidate function biomolecules. In addition improved throughput resulting parallelisation...
The VESUVIO spectrometer at the ISIS pulsed neutron and muon source is a unique instrument amongst those available facilities. This only inverted-geometry accessing values of energy wavevector transfer above tens eV ${\mathring{\rm A}}^{-1}$ , respectively, where deep inelastic scattering experiments are routinely performed. As such, procedure base technique has been previously described in an article published by this journal (Mayers Reiter 2012 Meas. Sci. Technol. 23 045902). recently...
The cold neutron imaging and diffraction instrument IMAT at the second target station of pulsed source ISIS is currently being commissioned prepared for user operation. will enable white-beam radiography tomography. One benefits operating on a to determine energy via time flight measurement, thus enabling energy-selective energy-dispersive imaging, maximizing image contrasts between given materials mapping structure microstructure properties. We survey hardware software components data...
The MAPS direct geometry time-of-flight chopper spectrometer at the ISIS pulsed neutron and muon source has been in operation since 1999, its novel use of a large array position-sensitive detectors paved way for later generations spectrometers around world. Almost two decades experience user operations on MAPS, together with lessons learned from new generation instruments, led to decision perform three parallel upgrades instrument. These were replace primary beamline collimation supermirror...

The ambitious instrument suite for the future European Spallation Source whose civil construction started recently in Lund, Sweden, demands a set of diverse and challenging requirements neutron detectors. For instance, unprecedented high flux expected on samples to be investigated diffraction or reflectometry experiments requires detectors that can handle counting rates, while investigation sub-millimeter protein crystals will only possible with large-area achieve position resolution as low...
This paper reports on the development and commissioning of GP2 detector. was developed to address requirement for a high-resolution event-mode imaging detector, application in energy-resolved neutron radiography. The name derives from use gadolinium as conversion material, combined with second-generation mass spectrometry sensor known PImMS2. Theoretical measured characteristics are compared, emphasis usability functionality detector has been steered by design philosophy which established...
