Notes

  • CERN (European Organisation for Nuclear Research) operates the Large Hadron Collider (LHC), a 27-km underground ring on the Franco-Swiss border.
  • LHC accelerates protons to 6.8 TeV per beam to simulate conditions of the early universe and study fundamental particles.
  • The High-Luminosity LHC upgrade, costing $1.5 billion, aims to increase collision frequency by five times to improve chances of detecting exotic particles.
  • Key achievements of LHC include the 2012 discovery of the Higgs boson, verification of the Standard Model, and creation of quark-gluon plasma.
  • Future objectives include searching for dark matter, dark energy, and evidence beyond the Standard Model.
  • The Future Circular Collider (FCC) is proposed as a 91-km tunnel with a cost estimate of $19 billion, with a decision due in 2028.
  • India has been collaborating with CERN since the 1960s; there is a push for increased Indian industrial participation in design phases.
  • Challenges for future large-scale scientific infrastructure include high costs, economic constraints, and debates regarding the scientific value of precision-focused versus power-focused machines.
