Below is a list of neutrino experiments we are actively involved in.
The SNO+ experiment is an upgrade to the original Sudbury Neutrino Observatory (SNO) which is well known for its discovery of neutrinos changing flavors. SNO+ is planning to fill the detector with Tellurium-doped liquid scintillator and will search for a very rare nuclear decay called neutrinoless double beta decay. Additionally, SNO+ will have sensitivity to a variety of physics such as reactor antineutrino oscillations, low-energy solar neutrinos, and geoneutrinos, supernova neutrinos, and exotic physics involving axions produced in the Sun.
The Water Cherenkov Monitor of Antineutrinos - Advanced Instrumentation Testbed (WATCHMAN-AIT) is a gadolinium-doped water Cherenkov neutrino detector that will support the development of detection hardware and algorithms to enable improved nonproliferation detector capabilities for remote monitoring of nuclear reactors. It will be constructed in Boulby Underground Laboratory, an existing U.K. government-funded deep underground science facility operating in a working potash, polyhalite and salt mine (Boulby Mine) located on the northeast coast of England. The goal is to demonstrate the capability of monitoring reactor operations, like the turning ON and OFF of a single core in the Hartlepool two-core reactor complex, 25 kilometers distant from the mine. In addition to reactor monitoring, the experiment is also pursuing R&D focused on the use of Water-based Liquid Scintillator (WbLS), large format fast photosensors such as the Large Area Picosecond PhotoDetectors (LAPPDs), and improved conventional Photomultiplier Tubes. These developments will allow WATCHMAN to serve as a 5% scale prototype for the proposed THEIA experiment. See the New York Times press release!
CAPTAIN is a liquid argon time projection chamber (LArTPC) that has been designed to study the interactions of neutrons and neutrinos in argon. These measurements will provide the first insight into the identification and reconstruction of similar interactions in a future detector known as the Deep Underground Neutrino Experiment (DUNE). Understanding neutrino and neutron interactions in argon is critical to the science motivation DUNE which aims to measure differences between the flavor oscillations of neutrinos and anti-neutrinos, also known as "charge-parity" violation or CP-violation.
Theia is a concept for a future detector filled with approximately 50,000 tons of water-based liquid scintillator (WbLS). Theia would combine the capability of a Water Cherenkov detector with a liquid scintillator detector to enable a very broad range of neutrino science involving high-energy neutrinos produced by particle accelerators down to very low energy neutrinos produced in the core of the Sun. The possibility of loading the Theia detector with neutrinoless double beta decay isotopes is of great interest.
NuDot is an idea to suspend quantum dots made from neutrinoless double beta decay isotopes in liquid scintillators. Quantum dots are semiconductor particles having sizes of roughly several nanometers and can be tuned to emit light over a broad spectrum of wavelengths. The ultimate goal of using quantum dots is to demonstrate the separation of Cherenkov rings from scintillation light. In a large detector, this would enhance the neutrinoless double beta decay signal and suppress backgrounds.
