Abstract:

This paper proposes a new position detector using frosted glass and four photo detectors. Four photo detectors are arranged under the four corners of the rough surface of frosted glass. When this sensor is irradiated by laser pointer, the light repeats reflection in the frosted glass and arrives at the photo detectors. The light intensity decreases by the increasing of distance between the photo detector and the irradiating point. Therefore, the distance between a photo detector and the irradiation point can be worked out from the output of the photo detectors. Thus, the light irradiation poin

Abstract:

Intensified diode arrays and charge-coupled detectors (CCD) which are used as multichannel detectors for spectroscopy exhibit strong 2-D diffraction of light due to the micro-channel plate intensifier and the CCD surface microelectronic structures. The strong 2-D diffraction of light by the intensified diode arrays shows hexagonal symmetry due to the hexagonal packing of the hollow glass fibers of the micro-channel plate intensifier. The 2-D diffraction of light from the CCD detectors shows square symmetry due to the almost square symmetry of the individual surface microelectronic structures.

Abstract:

Excessive light to detectors can be very harmful. Too much light, either monochromatic or wide band, can easily destroy photomultiplier tubes (PMTs). Charge-coupled devices (CCDs) cameras, of modern design, are typically made with cut-outs so that saturation beyond several pixels will cause them to shut off. Unfortunately, the detectors in the back of your eyes do not have automatic shut-off mechanisms, and can be easily destroyed with excessive light.As a review of filters and cubes, keep in mind that the primary job for the excitation filter is to block all light other than the desired band

Abstract:

Conversion of light detector signals to intensity values is one of the most important factors influencing precision of spectroscopic observations. Most of the classical light detectors used in astronomical practice are more or less nonlinear. As the photoemulsion has long been the most widespread nonlinear light detector, many improvements in the calibration methods concerned its nonlinearity. In addition to it, there are other substantial sources of inaccuracy in the calibration process of real astronomical images and spectrograms. They are mostly related to real light conditions in telescope

Abstract:

Single-photon detectors have gained significant attention recently, driven by advancements in quantum information technology. Applications such as quantum key distribution, quantum cryptography, and quantum computation demand the ability to detect individual quanta of light and distinguish between single-photon states and multi-photon states, particularly when operating within waveguide systems. Although single-photon detector fabrication has been established for some time, integrating detectors with waveguides using new materials with suitable structural and electronic properties, especially

Abstract:

Abstract Imaging Cherenkov detectors form the backbone of particle identification (PID) at the future Electron Ion Collider (EIC). Currently all the designs for the first EIC detector proposal use a dual Ring Imaging CHerenkov (dRICH) detector in the hadron endcap, a Detector for Internally Reflected Cherenkov (DIRC) light in the barrel, and a modular RICH (mRICH) in the electron endcap. These detectors involve optical processes with many photons that need to be tracked through complex surfaces at the simulation level, while for reconstruction they rely on pattern recognition of ring images.

Abstract The DarkSide-20k experiment represents the present goal of the Global Argon Dark Matter Collaboration program. Bringing together the experience from previous argon-based detectors, as well as the knowledge gained on large volume membrane cryostats developed within the DUNE program, the community is now building a dual-phase LAr-TPC equipped with SiPM arrays for light readout. The main goal of the experiment is to discover or to extend the current sensitivity limits on the search for dark matter WIMP-like particles. Currently, the experiment has entered the construction phase and the e

Abstract:

The TAIGA gamma observatory is continuing its deployment at the Tunka valley, close to lake Baikal. The new, original detectors, able to work under severe conditions of Siberia, were developed to increase the TAIGA sensitivity for the study of gamma-quanta at energies about 1 PeV and above. The distinguishing feature of the detectors is the use of the wavelength shifting light guides for scintillation light collection on a photodetector. Several designs of the counters have been tested: equipped with PMT or SiPM photo-detectors, acrylic or polystyrene based scintillators with thickness from 1

Abstract:

A new method for determining the coordinates in position-sensitive detectors with an organic fiber and silicon photomultipliers is described. This method differs from previously used spectrum-shifting fibers or an array of light-sensitive elements. It is based on the absorption of photons in the volume of the fiber and the reduction in the number of photons. Depending on the path length, the number of photons incident on the surface of the silicon photomultiplier varies. The optical parameters of a one-dimensional position-sensitive detector are simulated and the effect of the fiber coating on

We present here the manufacturing and experimental setup used to operate this detector at low transport electric fields (2.7–5.2 V/μm) and across a wide range of temperatures (77 K–290 K).

Abstract GRAIN (GRanular Argon for Interaction of Neutrinos) is a Liquid Argon detector which is part of the Near Detector complex of DUNE experiment. Most conventional noble liquid detectors employ scintillation light as either a timing signal for a TPC or as a calorimetric measurement, or both. The signal's relative amplitude and timing on multiple detectors can also be used to approximately locate an interaction. In GRAIN we go a step further, by using scintillation light to reconstruct images of tracks associated to charge particles in Liquid Argon volume. In fact, by developing a suitable

The development derives from the charged coupled device (CCD) for light-signal imaging, utilizing the extremely low capacitance of the detector and readout electronics and subsequent developments of silicon drift detectors for high-energy physics applications and more recently, x-ray spectroscopy applications. The now well-known advantage of the drift detector design is that, unlike traditional planar detectors,

Abstract The β-Ga2O3 ultraviolet (UV) detectors work in the solar-blind (UV) band due to the ultra-wide bandgap of β-Ga2O3. In this paper, a solar-blind ultraviolet detector based on an ordered nanoporous β-Ga2O3 (ONP-β-Ga2O3) film is proposed and implemented. The local enhancement effect of the ordered nanopores on light is simulated by finite-difference time-domain method, and the period and diameter of the nanopores are optimized. Graphene is transferred on the ONP-β-Ga2O3 film and prepared as interdigital electrodes of the solar-blind ultraviolet detectors. The optimal detector has a photo
