12/8/19, 3:30 PM

Non-noble Scintillators

Talk

The 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...

Prof. Gabriel Orebi Gann (UC Berkeley / LBNL), Dr Javier Caravaca (UC Berkeley)

12/8/19, 3:50 PM

Non-noble Scintillators

Talk

A 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...

Dr Michael Febbraro (Oak Ridge National Laboratory)

12/8/19, 4:10 PM

Non-noble Scintillators

Talk

Progress 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...

Dr Pieter Mumm (NIST)

12/8/19, 4:30 PM

Non-noble Scintillators

Talk

Organic 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 earth’s surface. When...

In 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. A wide range of base solvents and dye have been assessed to improve scintillator detection performance and material mechanical characteristics. Two distinct chemistries have been developed to solubilize Li-6 compounds in...

Dr J. Pedro Ochoa-Ricoux (University of California at Irvine)

12/8/19, 5:10 PM

Non-noble Scintillators

Talk

LiquidO 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...

With picosecond level timing resolution and multiple Large Area Picosecond Photodetectors (LAPPDs) in a time-of-flight configuration, pions and kaons may be separated up to 10-20 GeV.

Photodetectors

Talk

This 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...

24. NuDot: Fast Photodetectors for Double-Beta Decay with Direction Reconstruction

Dr Julieta Gruszko (MIT, UNC Chapel Hill)

12/9/19, 3:30 PM

Photodetectors

Talk

As 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...

71. Using Switchable Fluorescent Molecules to Image Tracks and Measure Energy in Large Liquid Double Beta Decay Detectors

Eric Spieglan (University of Chicago)

12/9/19, 3:50 PM

Photodetectors

Talk

We 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...

PROSPECT, the Precision Reactor Oscillation and Spectrum Experiment, has both carried out a sensitive search for sterile neutrino oscillations as a solution the reactor antineutrino anomaly and made the first modern measurement of the 235U reactor antineutrino spectrum. While no signature of sterile neutrinos has thus far been found, viable oscillation parameter space remains and efforts to...

Cosmogenic backgrounds represent a challenge for many experiments vitally important to achieving P5 science drivers, from on-surface neutrino detectors, such as Fermilab’s SBN Program, to various deep-underground experiments, like DUNE and LZ. Characterization of neutron background is necessary in dark matter and astrophysical neutrino measurements. Neutrons created in beam dump and...

Photodetectors

Talk

In the next decade several flagship Dark Energy surveys (DESI, EUCLID, LSST) will be nearing completion and interest in a next-generation experiment is increasing. One promising new technique is intensity mapping (IM), which unlike prior surveys uses the redshifted 21-cm emission from neutral hydrogen in galaxies to trace Large Scale Structure in three dimensions. The systematics associated...

Imaging surveys such as the Dark Energy Survey and LSST record the positions, shapes, magnitudes, and colors in a few filter bandpasses of 0.6B to 4B galaxies. Precision redshifts of hundreds of millions of galaxies are enabled by technologies that allow of to accumulate photons from thousands of individual objects in parallel. More cost-effective, smaller-scale optical fiber...

Metalenses are optical devices that implement nanostructures as phase shifters to focus incident light. Their compactness, simple fabrication and low cost make them a novel viable solution for increasing light collection efficiency in particle detectors with limited area coverage by light sensors. We report on the performance of metalenses in increasing the light collection efficiency of...

Photodetectors

Talk

Many current and future elementary particle physics experiments require detection of light emitted in the UV wavelength range. This includes neutrino experiments in liquid Argon (128 nm scintillation) or water (~200 nm Cerenkov), dark matter and neutrinoless double beta decay experiments in gaseous or liquid Xenon (175 nm scintillation) and calorimetry with crystals in g-2 (PbF2 Cerenkov) and...

78. Novel Small-Gap Materials as Photodetectors

Prof. Jeffrey Filippini (UIUC), Dr Noah Kurinsky (Fermi National Accelerator Laboratory)

12/10/19, 12:00 PM

Photodetectors

For 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...
