Dual-Cathode CsI Covered Microstrip Plate as VUV High Efficiency Photosensor [PDF]

open access: yes, 1994
A Gas Proportional Scintillation Counter based on a dual-cathode Microstrip Plate covered with a CsI film is described. This new dual-cathode technique has the advantage of increasing the VUV sensitive area of the Microstrip Plate. A detailed description

Energy loss of high energy cosmic rays in a liquid scintillator [PDF]

open access: yes, 1964
The characteristics of a large-area liquid scintillation counter are investigated and the uniformity of response of the counter over its area is measured and compared with theory.

Development of an anti-Compton veto for HPGe detectors operated in liquid argon using Silicon Photo-Multipliers

open access: yes, 2011
A proof of concept detector is presented for scintillation light detection in liquid argon using Silicon Photo-Multipliers. The aim of the work is to build an anti-Compton veto for germanium detectors operated directly in liquid argon like in the GERDA ...

Invisible Labor and the “Ghost Particle”: Underground Physics at the Kolar Gold Fields**

open access: yesBerichte zur Wissenschaftsgeschichte, EarlyView.
Abstract When cosmic rays—high‐energy particles from outer space—encounter the Earth's atmosphere, they produce particles called neutrinos. To detect them, physicists go underground inside deep mines where the overlying rock can filter out the cosmic‐ray background radiation.

In Vitro Antiplasmodial Activity and Chemical Composition of Combretum aculeatum, a Medicinal Plant From Niger

open access: yesChemistry &Biodiversity, EarlyView.
Workflow of current study. ABSTRACT Malaria remains a significant public health challenge in Niger, accounting for 5.6% of global malaria‐related deaths. Local medicinal plants are frequently used as traditional treatments for malaria, although their efficacy and safety are often insufficiently investigated.

Why Hoffmann? His Chemistry**

open access: yesThe Chemical Record, Volume 22, Issue 12, December 2022., 2022
Roald Hoffmann was the perfect theoretical chemist to collaborate with R. B. Woodward on the Principle of Conservation of Orbital Symmetry. This essay presents Hoffmann's capabilities as of May 5, 1964. Abstract Abstract: Why was it that Roald Hoffmann was the perfect collaborator for R. B.

Simulation of Scintillator Counters with Embedded Wavelength-Shifting Fibers [PDF]

open access: yesarXiv, 2019
We describe a complete end-to-end simulation of the response of scintillator counters to charged particles. The counters were extruded with a titanium dioxide surface coating and two channels for the embedded wavelength-shifting fibers which are read out by silicon photomultipliers.
