Gas micro-flow-metering with the in-channel Pt resistors

Journal of Telecommunications and Information Technology, 2005
Standard thermo-conductive gas flow meters have the side-channel integrated with the temperature detector and heater coils, both winded around the tube. This design suffers from a high thermal capacity, reduced sensitivity in the lower limit flow range,

Exploring the Interaction of Cosmic Rays with Water by Using an Old-Style Detector and Rossi’s Method

Particles, 2023
Cosmic ray air showers are a phenomenon that can be observed on Earth when high-energy particles from outer space collide with the Earth’s atmosphere. These energetic particles in space are called primary cosmic rays and consist mainly of protons (about ...

Probing the potential of CdZnTe for high-energy high-flux 2D X-ray detection using the XIDer incremental digital integrating readout

Frontiers in Physics
The latest synchrotron radiation sources have the capability to produce X-ray beams with a photon flux that can be up to three orders of magnitude higher than previous-generation facilities, and that are not manageable by the currently available 2D ...

Relativistic Quantum Information in Detectors-Field Interactions

, 2012
We review Unruh-DeWitt detectors and other models of detector-field interaction in a relativistic quantum field theory setting as a tool for extracting detector-detector, field-field and detector-field correlation functions of interest in quantum ...

INFRARED DETECTORS

Journal of Engineering Science (Chişinău), 2018
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 ...

An x-ray detector using PIN photodiodes for the axion helioscope [PDF]

, 2001
An x-ray detector for a solar axion search was developed. The detector is operated at 60K in a cryostat of a superconducting magnet. Special care was paid to microphonic noise immunity and mechanical structure against thermal contraction.
