Antineutrino Detection

Neutrinos provide a glimpse into some of the most obscured phenomena in high energy physics, but their precise nature and role in the universe remains a mystery.

Almost 60 years after their first detection, neutrino research remains an active and fruitful pursuit in the fields of particle physics, astrophysics, and cosmology. In addition to nuclear reactors and the Sun, detected neutrino sources include particle accelerators, the atmosphere , core-collapse supernovae, the Earth, and most recently the cosmos.

ANNIE: Accelerator Neutrino Neutron Interaction Experiment

 

Neutron tagging in Gadolinium-doped water may play a significant role in reducing backgrounds from atmospheric neutrinos in next generation proton-decay searches using Megaton-scale Water Cherenkov detectors, as well as future detection of  Supernova neutrinos. Accurate determination of neutron tagging efficiencies will require a detailed understanding of the number of neutrons produced by neutrino interactions in water, as a function of momentum transferred. Ultralytics is a partner in the Atmospheric Neutrino Neutron Interaction Experiment (ANNIE) collaboration, designed to measure the neutron yield of atmospheric neutrinos in gadolinium-doped water.

LAPPD: Large Area Picosecond Photo-Detector

30-Channel single side readout card for stripline-anode large area picosecond photo detector. each stripline is sampled at up to 10gs/s.

The University of Chicago, Argonne, Fermilab and Berkeley are interested in the development of large-area systems to measure the time-of-arrival of relativistic particles with picosecond resolution. These are respectively a factor of 100 and 20 better than the present state-of-the-art. This would involve development in a number of intellectually challenging areas: three-dimensional modeling of photo-optical devices, the design and construction of fast, economical, low-power electronics, the `end-to-end' (i.e. complete) simulation of large systems, real-time image processing and reconstruction, and the optimization of large detector and analysis systems for medical imaging.

MTC: MiniTimeCube

The miniTimeCube (mTC) is the world’s smallest neutrino detector. The mTC is a multipurpose detector, aiming to detect not only neutrinos but also fast/thermal neutrons and gammas. Potential applications include the counterproliferation of nuclear materials and the investigation of antineutrino short-baseline effects. The mTC is a plastic 0.2% 10B–doped scintillator 13 × 13 × 13 cm3 cube surrounded by 24 8×8 Micro-Channel Plate (MCP) photon detectors totaling 1536 individual channels/pixels viewing the scintillator. It uses custom-made electronics modules which mount on top of the MCPs, making our detector compact and able to both distinguish different types of events and reject noise in real time. The detector is currently deployed and being tested at the National Institute of Standards and Technology (NIST) nuclear reactor (20 MWth) in Gaithersburg MD, where it has undergone tests using neutron sources. The shield for further tests is being constructed, calibration is ongoing, and we are currently preparing the electronics for a major upgrade. As a novel design with unprecedented spatial and temporal resolution, this detector will be able to determine particle directions beyond previous capabilities.

SFM: Structure From Motion

 

Traditional Structure From Motion (SFM) techniques may be extended to the GPS/INS systems found in most of today's small aerial UAVs. Ultralytics specializes in processing Full Motion Video (FMV) from these platforms for the purposes of extracting real-time Digital Elevation Models (DEMs).

Neutron and Gamma (γ) Detection

Neutron and gamma detection via organic scintillator coupled to Silicon PhotoMultipliers (SiPMs) is a promising new direction in the fields of radiation safety and medical imaging.

Precise kinematic reconstruction of the neutron path through the detector allows for a robust probability mapping onto the sky of the original incoming neutron direction. Potential applications include radiation safety at nuclear power plants, cosmic-ray induced neutron background mapping, border security, and nuclear nonproliferation efforts.
