We present a characterization of small (9-liter) and mobile 0.1% 6Li-doped pulse-shape-sensitive plastic scintillator antineutrino detector called SANDD (Segmented AntiNeutrino Directional Detector), constructed for the purpose near-field reactor monitoring with sensitivity to direction. comprises three different types module. A detailed Monte Carlo simulation code was developed match validate ...

We discuss an alternative approach to the detection of solar neutrinos using a coarsely segmented detector based on inverse-beta decay onto 160Gd or 176Yb. While it is known that similar approaches, already discussed in the literature, can in principle provide low-threshold, real-time energy spectroscopy with intrinsic background rejection features, the concepts presented here make this scheme ...

The photoproduction of K mesons is an important challenge to recent QCD based chiral perturbation theories in the strange quark sector and is an important constraint on the nucleon excitation spectrum. We present preliminary data from a new high precision measurement using the Crystal Ball detector. The measurement pioneers a new technique for tagging strangeness using detailed cluster analysis...

The need to understand and reject backgrounds in Ge-diode detector double-beta decay experiments has given rise to the development of pulse shape analysis in such detectors to discern single-site energy deposits from multiple-site deposits. Here, we extend this analysis to segmented Ge detectors to study the effectiveness of combining segmentation with pulse shape analysis to identify the multi...

This paper overviews the history of infrared detector materials starting with Herschel’s experiment with thermometer on February 11th, 1800. Infrared detectors are in general used to detect, image, and measure patterns of the thermal heat radia− tion which all objects emit. At the beginning, their development was connected with thermal detectors, such as ther− mocouples and bolometers, which ar...

We present the design of the first level muon trigger in the central toroid of the ATLAS experiment at the Large Hadron Collider (LHC). The trigger is based on fast, finely segmented gaseous detector, Resistive Plate Chambers (RPC), to unambigously identify the interaction bunch crossing and to provide a sharp threshold over a large interval of transverse momentum. We describe the logic scheme ...

Segmented coaxial HPGe (High Purity Germanium) detectors have recently been shown to be feasible for Gamma Emission Tomography (GET). This type of detector allows a combination high efficiency and energy resolution in gamma spectrometry irradiated nuclear fuel. The ultimate aim developing segmented GET measurements is achieve spatial facilitate imaging rod-internal features interrogation smalle...

In this paper, human facial expressions are recognized based on the mouth feature using Susan edge detector [3,4]. Face part is segmented from the face image, in which mouth feature is separated and potential geometrical features are used for the determination of facial expression such as surprise, neutral, sad and happy. Experimentation is done on standard JAFFE database [8] images of differen...

Large area optical detection systems are required for applications including cell imaging, spectroscopy, nuclear medicine, bio diagnostics, radiation detection and high energy physics. Each of these applications requires that a detector or detector arrays be closely coupled with light sources or optical couplers such as fibres or light couplers. In this paper, the scaling of novel Silicon Photo...
