The detection and generation of single photons has seen an upsurge in interest in recent
years as new scientific fields of research, for example quantum information processing, have …

The human genome holds an extraordinary trove of information about human development,
physiology, medicine and evolution. Here we report the results of an international …

THE charge-coupled device (CCD) has become the detector of choice in optical astronomy.
CCDs provide a very linear response to detected photons, are very efficient at some …

GAIA is a preliminary concept for an astrometric mission, recently recommended within the
context of ESA'sHorizon 2000 Plus' long-term scientific programme. In its present form, the …

A review of cryogenic particle detectors is presented. A major motivation for develo** this
type of particle detector is their superior sensitivity to weakly ionizing particle interactions …

Some recent results associated with the development of tantalum based photon counting
superconducting tunnel junctions (STJ) suitable for use as broad-band low resolution …

A Josephson radiation threshold detector (JRTD) that is based on the threshold behaviour of
a current bias Josephson junction (CBJJ) is designed and fabricated for infrared radiation …

We are develo** time-and energy-resolved near-IR/optical/UV photon detectors based on
sharp superconducting-normal transition edges in thin films. We report observations of the …

Large-format ultraviolet image sensors have been and are actively being developed for a
variety of space-borne astronomy missions. The detector, which historically is one of the …

We report on the first astronomical observations with a photon-counting pixel detector that
provides arrival time (δ t= 100 ns) and energy (δ E γ≤ 0.15 eV) resolved measurements …
