First Results from the DEAP-3600 Dark Matter Search with Argon at SNOLAB. [PDF]

open access: yesPhysical Review Letters, 2017
This Letter reports the first results of a direct dark matter search with the DEAP-3600 single-phase liquid argon (LAr) detector. The experiment was performed 2 km underground at SNOLAB (Sudbury, Canada) utilizing a large target mass, with the LAr target

Argon neuroprotection [PDF]

open access: yesCritical Care, 2010
Certain noble gases, though inert, exhibit remarkable biological properties. Notably, xenon and argon provide neuroprotection in animal models of central nervous system injury. In the previous issue of Critical Care, Loetscher and colleagues provided further evidence that argon may have therapeutic properties for neuronal toxicity by demonstrating ...

Discovery of photospheric argon in very hot central stars of planetary nebulae and white dwarfs [PDF]

open access: yes, 2007
We report the first discovery of argon in hot evolved stars and white dwarfs. We have identified the ArVII 1063.55A line in some of the hottest known (Teff=95000-110000 K) central stars of planetary nebulae and (pre-) white dwarfs of various spectral ...

Ionization waves in nanosecond pulsed atmospheric pressure plasma jets in argon

open access: yesHigh Voltage, 2021
Typical ionization waves (IWs) are observed during the propagation of nanosecond pulsed atmospheric pressure plasma jets (APPJs) with argon flow, combining both the measurement of the axial electric field (Ez) and the temporal resolved optical imaging ...

Simulation of argon response and light detection in the DarkSide-50 dual phase TPC [PDF]

open access: yes, 2017
A Geant4-based Monte Carlo package named G4DS has been developed to simulate the response of DarkSide-50, an experiment operating since 2013 at LNGS, designed to detect WIMP interactions in liquid argon.

Arc pressure and weld metal fluid flow whilst using alternating shielding gases Part 2 : arc force determination [PDF]

open access: yes, 2013
The transient variation of the shielding gas present in the alternating shielding gas process produces a dynamic action within the liquid weld metal. Flow vectors opposite in direction have been reported due to the various forces acting on the weld metal
