C. O. Escobar, P. Rubinov, E. Tilly
TL;DR
This paper reports recent experimental results on near-infrared scintillation in liquid argon using Fermilab's NIR facility, supporting its potential application in large liquid argon detectors.
Contribution
It provides new empirical data confirming near-infrared scintillation in liquid argon with a dedicated cryostat at Fermilab.
Findings
Near-infrared scintillation observed in liquid argon.
Results support use of NIR light in large detectors.
Enhanced confidence in NIR as a detection signal.
Abstract
After a short review of previous attempts to observe and measure the near-infrared scintillation in liquid argon, we present new results obtained with NIR, a dedicated cryostat at the Fermilab Proton Assembly Building (PAB). The new results give confidence that the near-infrared light can be used as the much needed light signal in large liquid argon time projection chambers.11 pages,
