The successful operation of noble fluid particle detectors relies on adhering to stringent purity constraints. To take full advantage of the scintillation performance of liquid argon, sub-ppm levels of impurity concentrations must be achieved. Commercial providers do not reliably meet these requirements, thus creating the need for on-site purification. We designed and constructed a...
The X-ARAPUCA is an innovative photon detection device based on the use of a short pass dichroic filters with an appropriate cut-off wavelength, two wavelength shifters and an array of SiPM. This device was idealized and developed to detect liquid argon scintillation photons in large liquid argon time projection chambers (LArTPC). The scintillation light is produced in the vacuum ultraviolet...
The search for light dark matter (<10 $GeV/c^2$) has become increasingly important, since no conclusive evidence has been found in the higher dark matter (DM) mass region. In order to explore this light mass range, it is necessary to accurately model the response of the noble liquid time projection chamber (TPC) detectors, used in many experiments aimed at the direct measurement of DM, to low...
Dark matter searches using dual-phase xenon time projection chambers (LXe-TPC), such as LUX-ZEPLIN (LZ), use the ratio of charge signal to light signal to discriminate between electron recoils and nuclear recoils. The charge and light yields of electron recoils are often calibrated with 𝛽-decays, such as 3H and 212Pb. These 𝛽-decays produce recoils primarily from outer shell electrons, while...
Deep Learning (DL) is nowadays ubiquitous. In Particle Physics there is a wide portfolio of successful applications. Position reconstruction is one of the areas where DL has been applied in the past. In this talk we present preliminary research on position reconstruction DL-based in large liquid argon detectors, and a roadmap of future developments. Additionally, efforts to apply Explainable...
The Coherent CAPTAIN-Mills (CCM) experiment is a 10 ton liquid argon scintillation detector located at Los Alamos National Lab. The detector is located 23m downstream from the Lujan Facility's stopped pion source which will receive 2.25 * 10^22 POT in the ongoing 3 year run cycle. CCM is instrumented with 200 8-inch PMTs, 80% of which are coated in wavelength shifting tetraphenyl-butadiene,...
