Why in news?

  • The European Organization for Nuclear Research (CERN) has reignited the Large Hadron Collider for the third time in July2022 — 10 years after it enabled scientists to find the ‘God particle’ or Higgs Boson.

About Large Hadron Collider:

  • The Large Hadron Collider is a giant, complex machine built to study particles that are the smallest known building blocks of all things.
  • In its operational state, it fires two beams of protons almost at the speed of light in opposite directions inside a ring of superconducting electromagnets.
  • The magnetic field created by the superconducting electromagnets keeps the protons in a tight beam and guides them along the way as they travel through beam pipes and finally collide.
  • LHC’s powerful electromagnets carry almost as much current as a bolt of lightning; they must be kept chilled.
  • The LHC uses a distribution system of liquid helium to keep its critical components ultracold at minus 271.3 degrees Celsius, which is colder than interstellar space.

Significance:

  • Physicists want to use the collisions to learn more about the Universe at the smallest scales, and to solve mysteries such as the nature of dark matter.
  • The LHC's goal is to allow physicists to test the predictions of different theories of particle physics.
  • Technology found in particle accelerators is already used for certain types of cancer surgery etc.

Add ons:

  • First Run:
    • A decade ago, CERN had announced to the world the discovery of the Higgs boson or the ‘God Particle’ during the LHC’s first run.
  • Second Run:
    • It began in 2015 and lasted till 2018. The second season of data taking produced five times more data than Run 1.
