As liquid argon (LAr) detectors are made at progressively larger sizes, accurate models of
LAr optical properties become increasingly important for simulating light transport …

Performance studies of a ton scale liquid argon (LAr) dark matter detector (ArDM) are
presented in this thesis. The detector is designed for a direct search for weakly interacting …

Large liquid argon detectors have become widely used in low rate experiments, including
dark matter and neutrino research. However, the optical properties of liquid argon are not …

We report on a measurement of the absorption length of scintillation light in liquid argon due
to dissolved nitrogen at the part-per-million (ppm) level. We inject controlled quantities of …

Within our current understanding of the makeup of the universe, dark matter makes up 25%
of the total energy and over 80% of the matter in the universe. Little is known about the …

We report on a measurement of the attenuation length for the scintillation light in the tonne
size liquid argon target of the ArDM dark matter experiment. The data was recorded in the …

The midsize single-phase liquid argon prototype detector, operating at the surface
laboratory, is designed to measure scintillation light emitted by the liquid argon (LAr). The …

Liquid argon (LAr) is a common choice as detection medium in particle physics and rare-
event searches. Challenges of LAr scintillation light detection include its short emission …

There is wealth of evidence that the majority of the matter in the universe is composed of non-
baryonic dark matter. One candidate for dark matter is weakly interacting massive particle …

The properties of the propagation of scintillations light in the liquid argon, at λ= 128 nm
wavelength, has been experimentally investigated in a dedicated setup at CERN. The …
