“…The PTB is a highly flexible, programmable and configurable trigger board and its versions are currently also used in the ProtoDUNE and EOS experiments [2,3]. The board houses a commercial MicroZed TM board containing a Zynq ® -7Z020 System-On-a-Chip (SoC), which provides userprogrammable FPGA logic and a processing system with direct access to the FPGA.…”

The SBND experiment is a liquid argon time projection chamber (LArTPC), which serves as the near detector to the Short Baseline Neutrino (SBN) program at Fermilab. With only 110 m between the detector volume and the beam target, SBND will record over a million of neutrino interactions per year, more than any LAr experiment to date. Furthermore, the detector is located on the surface and exposed to cosmic rays. As a result, a sophisticated and reliable trigger system is needed to ensure high efficiency of neutrino data while maintaining data rates which are manageable in downstream analysis. This proceeding will detail how the SBND trigger system achieves both of these goals.

“…An understanding of the availability and performance of different large-area PMTs is crucial for future experiments, such as Theia [6], in the selection of sensors [7], as well as for accurately simulating the PMT response in existing detectors. The R14688-100 is one such large-area PMT, that will be used for the first time in a large-scale experiment in the Eos detector [8].…”

“…Eos is a 20-ton detector, designed to perform a demonstration of key technology for future advanced neutrino detectors [8] that plan to distinguish Cherenkov and scintillation light. This technology includes spectral sorting of photons [9], novel types of liquid scintillators [10,11], and fast timing photodetectors [12].…”

Large-scale optical neutrino and dark-matter detectors rely on large-area photomultiplier tubes (PMTs) for cost-effective light detection. The new R14688-100 8-inch PMT developed by Hamamatsu provides state-of-the-art timing resolution of around 1 ns (FWHM), which can help improve vertex reconstruction and enable Cherenkov and scintillation light separation in scintillation-based detectors. This PMT also provides excellent charge resolution, allowing for precision photoelectron counting and improved energy reconstruction. The Eos experiment is the first large-scale optical detector to utilize these PMTs. In this manuscript we present a characterization of the R14688-100 single photoelectron response, such as the transit-time spreads, the dark-rates, and the afterpulsing. The single photoelectron response measurements are performed for the 206 PMTs that will be used in Eos.

“…The THEIA detector will also be able to work on the sun, earth (Geo), and reactor neutrinos. The EOS [22] experiment is considered a portable detector with approximately four tons (fiducial) and is currently under construction at the University of California-Berkeley laboratories in the U.S.A. The ANNIE experiment conducted at Fermilab deployed WbLS in its experimental setup through the utilization of the SANDI box [23,24].…”

This research investigates the separation of Cherenkov and Scintillation light signals within a simulated Water-based Liquid Scintillator (WbLS) detector, utilizing the XGBoost machine learning algorithm. The simulation data were gathered using the Rat-Pac software, which was built on the Geant4 architecture. The use of the WbLS medium has the capability to generate both Scintillation and Cherenkov light inside a single detector. To show the separation power of these two physics events, we will use the supervised learning approach. The assessment utilized a confusion matrix, classification report, and ROC curve, with the ROC curve indicating a performance result of 0.96 ± 1.2× 10-4. The research also aimed to identify essential parameters for effectively distinguishing these physics events through machine learning. For this, the study also introduced the SHAP methodology, utilizing game theory to assess feature contributions. The findings demonstrated that the number of hits has a significant effect on the trained model, while the mean hit time has a somewhat smaller impact. This research advances the utilization of AI and simulation data for accurate Cherenkov and Scintillation light separation in neutrino detectors.
