Science and Technology

Baikal-Gigaton Volume Detector (GVD):

Why in News?

Russian scientists recently launched one of the world’s largestunderwater neutrino telescopes called Baikal-GVD underwater Lake Baikal.

About Baikal- GVD:

  • It is designed to study in detail the elusive fundamental particles called neutrinos and also to possibly determine their sources.
  • Other large neutrino detectors in the world:
    • IceCube at the South Pole
    • ANTARES in the Mediterranean Sea.

About Neutrinos:

  • The neutrino is also a tiny elementary particle, like protons and electrons, but arenot part of the atom. Such particles also exist in nature.
  • It has a very tiny mass and no charge.
  • It interacts extremely weakly with other matter particles. Hence, every second trillion of neutrinos falling on us pass unnoticed.
  • Source of Nutrinos:
    • Sun- Solar neutrinos
    • Stars:Stellar neutrinos,
    • Cosmic rays coming from beyond the solar system,
    • From the Big Bang from which our Universe originated.
    • They can also be produced in the lab.
  • The INO will study atmospheric neutrinos only. Solar neutrinos have much lower energy than the detector can detect.
  • Applications of Neutrino Science:
    • Properties of the sun
    • Constituents of the Universe
    • Probing early Universe
    • Medical Imaging, etc
  • India-based Neutrino Observatory (INO) is also envisioned with Tata Institute of Fundamental Researchas the nodal institution in Bodi West Hills (Theni district) of Tamil Nadu.
