AMIGA (Auger Muons and Infill for the Ground Array) is an upgrade of the Pierre Auger Observatory designed to extend its energy range of detection and to directly measure the muon content of the cosmic ray primary particle showers. The array will be formed by an infill of surface water-Cherenkov detectors associated with buried scintillation counters employed for muon counting. Each counter is ...

This paper is a definition of photo elicitation and a history of its development in anthropology and sociology. The view of photo elicitation in these disciplines, where the greatest number of photo elicitation studies have taken place, organizes photo elicitation studies by topic and by form. The paper also presents practical considerations from a frequent photo elicitation researcher and conc...

Flexible X-ray storage phosphor sheets are regarded as promising alternatives to conventional electronic flat-panel detectors, enabling imaging and dosimetry in less accessible situations. However, it is a challenge develop phosphor-based detectors with high memory stability convenient readout processes. Here, an approach realize this using radiation-induced photoluminescence tuning (Ba1-xSrx)2...

Abstract We report on development of an array spectral sensitive detectors cooled down to 70 K by the compact cryocooler. The operation detectors, explored between 0.16 THz and 0.22 THz, is due resonant excitation plasma waves in two-dimensional electron gas GaAs/AlGaAs heterostructure. A typical responsivity 0.01 A/W at while it increases two orders magnitude when detector 0.5 K. photo-respons...

Black silicon (b-Si) featured by anti-reflective surfaces is extensively studied to realize highly sensitive photodetectors. The key augmenting the light-detection capability of b-Si facilitate charge extraction while limiting undesired recombination events at surface defects. To this end, oxidative chemical vapor deposition (oCVD) leveraged form a conformal and conductive (3000 S cm−1) organic...

Bonding arrays of hundreds of photo-detectors and VCSELs to silicon substrates has been demonstrated [1-2] and scaling to thousands of devices is possible. To support these large numbers of optical IO, very small and low-power IO interface electronics is required. To remove both the speed and power trade-offs intrinsic in receiver that uses a transimpedance amplifier to convert the photo-curren...

Semiconductors play a critical role in optoelectronic applications, and recent research has identified group-VI 2D semiconductors as promising materials for this purpose. Here, we report the comprehensive excited state carrier dynamics of bilayer, two-dimensional (2D) selenium (Se) one-photon multi-photon absorption regimes using transient reflection (TR) spectroscopy. Carrier lifetime obtained...
