On Determining Dead Layer and Detector Thicknesses for a Position-Sensitive Silicon Detector [PDF]
In this work, two particular properties of the position-sensitive, thick silicon detectors (known as the "E" detectors) in the High Resolution Array (HiRA) are investigated: the thickness of the dead layer on the front of the detector, and the overall ...

Infrared detectors have wide application in a range of industry sectors, including defence, astronomy, medicine, environmental safety, and remote sensing. The applications requiring the highest sensitivity over a broad spectrum of wavelengths are usually based on the high performance mercury cadmium telluride HgCdTe ternary alloy, since HgCdTe-based ...

Gravitational wave detector response in terms of spacetime Riemann curvature
Gravitational wave detectors are typically described as responding to gravitational wave metric perturbations, which are gauge-dependent and --- correspondingly --- unphysical quantities.

Non-dispersive infrared multi-gas sensing via nanoantenna integrated narrowband detectors
Non-dispersive infrared (NDIR) spectroscopy analyzes the concentration of target gases based on their characteristic infrared absorption. In conventional NDIR gas sensors, an infrared detector has to pair with a bandpass filter to select the target gas ...

An improved negative selection algorithm based on the hybridization of cuckoo search and differential evolution for anomaly detection [PDF]
The biological immune system (BIS) is characterized by networks of cells, tissues, and organs communicating and working in synchronization. It also has the ability to learn, recognize, and remember, thus providing the solid foundation for the ...

Study of the coincidences between the gravitational wave detectors EXPLORER and NAUTILUS in 2001 [PDF]
We report the result from a search for bursts of gravitational waves using data collected by the cryogenic resonant detectors EXPLORER and NAUTILUS during the year 2001, for a total measuring time of 90 days.
