Abstract We present several novel ionization-electron and scintillation-photon recording concepts in noble-liquid detectors, for future applications particle astroparticle physics other fields. These involve both single- dual-phase detector configurations with combined electroluminescence small charge multiplication gas liquid media.

The mineral content of bone can be determined by measuring the absorption by bone of a monochromatic, low-energy photon beam which originates in a radioactive source (iodine-125 at 27.3 kev or americium 241 at 59.6 kev). The intensity of the beam transmitted by the bone is measured by counting with a scintillation detector. Since the photon source and detector are well collimated, errors result...

Losses from the proton and antiproton beams of the Fermilab Tevatron have been shown to produce a halo which contribute to backgrounds to physics signals in the Collider Detector at Fermilab (CDF). To provide a measure of the beam halo and losses, we have installed arrays of scintillation counters on both sides of the CDF detector. We describe here the physical configuration of these counters, ...

Development of a small area (1–2 cm) in situ beta imaging device includes optimization of the front end scintillation detector, which is fiber optically coupled to a remote photon detector. Thin plastic scintillation detectors, which are sensitive to charged particles, are the ideal detectors due to the low sensitivity to ambient gamma backgrounds. The light output of a new binary plastic scint...

Abstract DEAP-3600 is a single-phase liquid argon (LAr) dark matter detector, located 2 km underground at SNOLAB in Sudbury, Canada, which started taking data 2016. The detector sensitive to nuclear recoils induced by scattering of particles, would cause emission prompt scintillation light. demonstrated excellent performance, holds the leading WIMP exclusion among LAr detectors, and published s...

ZnS nanoparticles (NPs) doped with ‎Ag‎, ‎Cu‎, ‎and AgCu were synthesized using hydrothermal‎ ‎method in water solution‎. ‎The NPS are characterized by X-ray diffraction (XRD)‎, ‎energy-dispersive‎ ‎X-ray spectroscopy scanning (EDX)‎, ‎scanning electron‎ ‎microscopy (SEM) and dynamic light scattering (DLS)‎. ‎The produced NPs have approximately hexagonal structure and a cubic zinc blended struc...
