Position Sensitive Detectors play a key role in X-ray and Gamma-ray Astronomy
as they allow imaging and spectroscopy of astrophysical sources throughout
the Universe. At these high energies, photons are generally characterized
individually, requiring sensitive and rapid low-noise charge amplifiers to extract
the information. In this review I will describe the detector technologies that...

Oral Contribution
We developed a TPC with optical readout with the goal of detecting the sense and direction of the elastic recoils generated by Dark Matter interactions. The detector, filled with CF4 gas at low pressure, is equipped with a mesh-based amplification region that allows for a 2D imaging of the recoils in a CCD camera. The third coordinate of the recoil is provided by PMTs. The sense of the...

ZEPLIN-III is a position-sensitive liquid xenon time projection chamber which is currently collecting data in a deep underground laboratory at Boulby in North Yorkshire, UK. It's science goal is the direct detection of Galactic dark matter particles and it is specifically designed to be sensitive to neutralinos predicted by supersymmetry. We will present results on instrument performance...

Oral Contribution
In this work, we present the results of the experimental characterization of the DRAGO gamma camera, developed within an Italian INFN project. This camera, based on the Anger camera topology, is based on a monolithic array of 77 Silicon Drift Detectors (SDDs), with an active area of 6.7 cm2, coupled to a single CsI(Tl) scintillator crystal, 5mm thick. The use of an array of SDDs allows to...
