Operation of a negative ion gas time projection chamber without electronegative fill gases
Lachlan J. McKie, Lindsey J. Bignell, Nicholas Adams +3
The high fidelity reconstruction of particle tracks in micropatterned gaseous time projection chambers renders this technology ideal for future rare-event searches, including direc…
In-situ suppression of surface radon emanation using an HDPE barrier at the Stawell Underground Physics Laboratory (SUPL)
R. R. Marcelo Gregorio, K. Mintern-Lane, S. Rushbrook +5
Radon-induced backgrounds remain a limiting factor in low-background experiments conducted in underground laboratories. The enclosed nature of these laboratories can result in elev…
Direct in-chamber radon-220 (thoron) emanation measurements for rare-event physics experiments
R. R. Marcelo Gregorio, F. Dastgiri, A. Basharina-Freshville +7
Measuring radon emanation from detector materials is a key method for controlling radon, a significant background in rare-event physics experiments. Methods for measuring radon ema…
Photomultiplier Requirements and Pre-Calibration for the SABRE South Liquid Scintillator Veto
L. J. Milligan, P. Urquijo, E. Barberio +32
We present a study of the oil-proof base Hamamatsu R5912 photomultiplier tubes that will be used in the SABRE South linear-alkylbenzene liquid scintillator veto. SABRE South is a d…
Performance of a Ton-scale Water-based Liquid Scintillator Detector
Rong Zhao, Lindsey Bignell, David E. Jaffe +4
This study reports the performance and light yield of 1% concentration water-based liquid scintillator (WbLS) deployed in a 1000-liter detector. A light yield of 9915 photons…
Quenching factor measurements of sodium nuclear recoils in NaI:Tl determined by spectrum fitting
L. J. Bignell, I. Mahmood, F. Nuti +21
We have performed measurements of sodium nuclear recoils in NaI:Tl crystals, following scattering by neutrons produced in a Li(p,n)Be reaction. Understanding the light…
