Neutrino data acquisition system

  • Has a neutrino ever been detected?

    A team including physicists has for the first time detected subatomic particles called neutrinos created by a particle collider, namely at CERN's Large Hadron Collider (LHC)..

  • How do you capture neutrinos?

    The Super-Kamiokande neutrino observatory uses 50,000 tons of pure water surrounded by 11,200 sensitive light detectors 1 kilometer below ground in Japan.
    Neutrinos from space interact with the water and produce flashes of blue light.
    Technicians on a raft check the photodetectors (far right)..

  • How does neutrino detection work?

    In addition to the neutrino interactions visible in a regular water detector, a neutrino can break up the deuterium in heavy water.
    The resulting free neutron is subsequently captured, releasing a burst of gamma rays that can be detected..

  • What are neutrinos used for?

    Neutrinos also provide a tool to study the structure of nucleons (protons and neutrinos), to learn how matter evolved from simple particles into more complex composites of particles, creating everything around us..

  • A neutrino detector is a physics apparatus which is designed to study neutrinos.
    Because neutrinos only weakly interact with other particles of matter, neutrino detectors must be very large to detect a significant number of neutrinos.
  • Every time atomic nuclei come together (like in the sun) or break apart (like in a nuclear reactor), they produce neutrinos.
    Even a banana emits neutrinos—they come from the natural radioactivity of the potassium in the fruit.
    Once produced, these ghostly particles almost never interact with other matter.
The data acquisition system of the detector takes care of the digitisation of the photo-multiplier tube signals, data transport, data filtering, and data 

Observatory

The Baikal Deep Underwater Neutrino Telescope (BDUNT) is a neutrino detector conducting research below the surface of Lake Baikal (Russia) since 2003.
The first detector was started in 1990 and completed in 1998.
It was upgraded in 2005 and again starting in 2015 to build the Baikal Gigaton Volume Detector (Baikal-GVD.) BDUNT has studied neutrinos coming through the Earth with results on atmospheric muon flux.
BDUNT picks up many atmospheric neutrinos created by cosmic rays interacting with the atmosphere – as opposed to cosmic neutrinos which give clues to cosmic events and are therefore of greater interest to physicists.
