112. Road to PROSPECT-II

Franz Machado (Illinois Institute of Technology)

08/07/2024, 11:30

The Precision Reactor Oscillation and SPECTrum (PROSPECT) experiment is based in a segmented liquid scintillator antineutrino detector situated approximately 7 meters from the highly enriched High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory. Its main goal is to investigate short-baseline antineutrino oscillations.
The first phase of data collection, known as PROSPECT-I, was...

98. How Matter Matters: The Story of Time Invariance Violation in Neutrino Oscillations

Olivia Meredith Bitter (Fermilab/Northwestern)

While neutrino oscillations provide a well motivated probe for CP violation, non-trivial matter effects and our inability to build experiments in an anti-Earth limits our studies to improper tests of its effects. These limitations in turn motivate (from CPT theorem) time invariance studies, as under certain matter potential profiles, proper time invariance and improper time invariance are the...

90. Real-time Anomaly Detection for Charge-based Triggering in LArTPCs

Seokju Chung (Columbia University)

Modern particle detectors, including liquid argon time projection chambers (LArTPCs), collect a vast amount of data, making it impractical to save everything for offline analysis. As a result, these experiments need to employ different down-selection techniques during data acquisition, referred to as triggering. In this talk, I will present a framework that would enable real-time, data-driven...

56. 2x2 demonstrator in 10 minutes

52. 2x2 demonstrator in 10 minutes

Thomas Murphy

The 2x2 demonstrator is a prototype of the DUNE Near Detector (ND). Like the DUNE ND, the
2x2 features an array of modular, pixelated, LArTPCs and a muon tagging system (MINERνA)
Following its installation within the NuMI beam line later this year, the 2x2 will become the first
pixelated LArTPC to take neutrino data. The detector has an active LAr mass of 2.6 metric tons
and is equipped...

1. ANNIE in 10 minutes

The Accelerator Neutrino Neutron Interaction Experiment (ANNIE) is a 26-ton Gd-doped water Cherenkov R&D detector located upstream of the Booster Neutrino Beam (BNB) at Fermi National Accelerator Laboratory (Fermilab). The ANNIE physics goal is to study the neutron yield of the neutrino-nucleus interaction. The R&D effort focuses on using new photodetector technology, chemical additives, and...

35. Detection of MeV-Scale Gammas from Pion/Muon Nuclear Capture With the LArIAT Liquid Argon TPC

LArIAT (Liquid Argon In A Testbeam) is a LArTPC experiment which aims to understand and characterize interactions of neutrino final-state products with Argon. Differentiation between muons and pions in LArTPCs is difficult since the tracks for both particles exhibit very similar ionization densities. We are exploring unique new particle discrimination capabilities for pions and muons by...

4. Dopant R&D in LArTPCs

Neutrinos interact with matter very weakly making it hard to detect despite being the most abundant particle in the universe. Liquid Argon Time Projection Chamber (LArTPC) detects neutrinos by measuring the resultant charge and light after the interaction between neutrino and argon particles. However, in LArTPCs, light collection efficiency is much lower than charge...

6. NA61/SHINE Hadron Production Measurements for Accelerator-Based Neutrino Beams

Long-baseline neutrino experiments, such as NOvA, T2K, and DUNE, are working to measure neutrino oscillation parameters and will benefit from reduced neutrino flux uncertainties. The dominant source of neutrino flux uncertainty arises from an insufficient knowledge of parent hadron yields from neutrino production targets. Using external hadron production measurements, we can significantly...

43. Pions as a path to neutrino oscillations

The new neutrino beamlines under construction at Fermilab will run at energies producing many single-pion producing interactions at the corresponding detectors. The detectors themselves will facilitate the detection and reconstruction of this kind of interactions.
We try to examine if this "extra signal" can be used to accelerate the determination of oscillation parameters, and, mainly, how...
