Robert Svoboda (University of California, Davis)12/8/19, 3:30โฏPMNon-noble ScintillatorsTalkThe development of Water-based Liquid Scintillator could have a significant impact on the sensitivity of future large underground neutrino detectors due to the possibility of building hybrid scintillator/Cherenkov detectors that combine particle tracking with low threshold, improved energy resolution, and low cost. In this presentation the characteristics of such a hybrid detector are...Go to contribution page

Prof. Gabriel Orebi Gann (UC Berkeley / LBNL), Dr Javier Caravaca (UC Berkeley)12/8/19, 3:50โฏPMNon-noble ScintillatorsTalkA hybrid Cherenkov / scintillation experiment, that can leverage both signals in a single detector, would offer world-leading physics reach across a broad range of topics, from high-energy physics to nuclear and astrophysics. One way to realise such a detector would be the use of water-based liquid scintillator, a powerful target medium that can be tuned to meet the physics goals. In this...Go to contribution page

Dr Michael Febbraro (Oak Ridge National Laboratory)12/8/19, 4:10โฏPMNon-noble ScintillatorsTalkProgress in the fields of neutrino physics and dark matter searches have placed extreme demands for ultra-low background sensitivities. These improvements can be achieved by replacing inactive structural components with transparent, radio-pure plastic scintillators. These structural scintillating components can serve as an active veto, discriminating internal events of interest from external...Go to contribution page

Dr Pieter Mumm (NIST)12/8/19, 4:30โฏPMNon-noble ScintillatorsTalkOrganic scintillators with high light output, pulse shape discrimination (PSD) response and isotope doping are a promising avenue for achieving new levels of sensitivity to low-rate or low-energy processes. For example, 6Li-doped PSD scintillator enabled the PROSPECT experiment to achieve >104 background rejection in detecting MeV-scale reactor antineutrinos at the earthโs surface. When...Go to contribution page

Dr Viacheslav Li (LLNL)12/8/19, 4:50โฏPMNon-noble ScintillatorsTalkIn recent years, significant progress has been made at LLNL in synthesizing a new class of plastic scintillators that support Pulse Shape Discrimination (PSD) and Li-6 doping.

Dr J. Pedro Ochoa-Ricoux (University of California at Irvine)12/8/19, 5:10โฏPMNon-noble ScintillatorsTalkLiquidO is a revolutionary detection technique, which uses opaque organic scintillator and that consequently departs from the classical paradigm of highly transparent liquid scintillator (LS) detectors that has prevailed for decades. In LiquidO, scintillation light is confined near its creation point by the scintillation light's short scattering length due to the opaque nature and collected by...Go to contribution page

Prof. Andrew Brandt (University of Texas Arlington)12/9/19, 3:10โฏPMPhotodetectorsTalkThis detector R&D effort focusses on the development of long-life microchannel plate (MCP) photomultiplier tubes (PMTs) capable of high rate operations. MCP-PMTs typically use two compact lead glass plates with many small holes (pores) ~10 um under high voltage to provide electron multiplying functionality. The compact and segmented MCP-PMTs have the capacity to be photon detection devices of...Go to contribution page

Dr Julieta Gruszko (MIT, UNC Chapel Hill)12/9/19, 3:30โฏPMPhotodetectorsTalkAs neutrinoless double-beta decay searches seek to reach into and beyond the inverted hierarchy regime, new strategies are needed to reject background events in kiloton-scale detectors. In monolithic liquid-scintillator-based detectors, otherwise-irreducible backgrounds like $^8$B solar neutrino scattering could be identified by their event topology using Cherenkov light signals. This...Go to contribution page

Eric Spieglan (University of Chicago)12/9/19, 3:50โฏPMPhotodetectorsTalkWe propose a technique to use switchable fluorescent molecules to image ionization and to measure energy deposition in events in large liquid double beta decay detectors. A charged particle deposits energy in an organic solvent as in liquid scintillators. The excitations transfer energy to the initially non-fluorescent switching molecules and activate them into a fluorescent configuration. The...Go to contribution page

Prof. Jeffrey Filippini (UIUC), Dr Noah Kurinsky (Fermi National Accelerator Laboratory)12/10/19, 12:00โฏPMPhotodetectorsFor decades, we have used materials with sub-eV bandgaps as avalanche photo-diodes, with smaller gap materials allowing for detection of longer wavelength light. These applications have been largely restricted to high-power detection due to high dark rates observed in these detectors at room temperature. Recent progress has been made reducing the dark current by cooling these APDs to LN2...Go to contribution page
