The development of highly pixelated fast Medipix/Timepix readout enabled a large number of novel hybrid detectors, where incoming particles/photons are initially converted into a measureable charge, typically exceeding 1000 electrons. Among those pos

We present the concept of a single-photon imager capable of detecting up to 109 photons per second with simultaneous measurements of position (5–10 μm resolution) and time (few tens of picosecond resolution) for each individual photon over an acti

Many high resolution event counting devices process one event at a time and cannot register simultaneous events. In this article a frame-based readout event counting detector consisting of a pair of Microchannel Plates and a quad Timepix readout is d

The cold neutron spectrum of the Beamline for neutron Optics and other Applications (BOA) at Paul Scherrer Institut enables high contrast neutron imaging because neutron cross sections for many materials increase with neutron wavelength. However, for

The sharp variation of neutron attenuation at certain energies specific to particular nuclides (the lower range being from ~1 eV up to ~1 keV), can be exploited for the remote mapping of element and/or isotope distributions, as well as temperature pr

The unique capability of microchannel plates (MCPs) to convert a single photon/ electron/ ion/ neutron into a charge of 104 -107 electrons localized within 4-12 μm from the event position is widely used in event counting imaging detectors. The high
