Context:
Recently, India’s Department of Atomic Energy (DAE) stared the construction phase for contributions to Proton Improvement Plan II (PIP-II) project.
Proton Improvement Plan (PIP-II) Project:
- Built with significant contributions from international partners.
- International Collaborators – Institutions from India, France, Italy, Poland and UK
- It will power the world’s most high-energy neutrino beam to the underconstruction Deep Underground Neutrino Experiment (DUNE) at Long-Baseline Neutrino Facility (LBNF).
- It provides Indian scientists and engineers the training, technical insight and know-how for the development of their domestic particle accelerator program and future projects.
Particle Accelerators:
- A device that produces a beam of fast-moving, electrically charged atomic or subatomic particles
- It propels charged particles (Protons, Atomic Nuclei, Electrons etc.) at high speeds, close to the speed of light.
- 4 principal components of accelerator –
- Source for producing particles
- Composite device to speed them up
- Metallic tubes in vacuum to allow free movement
- Electromagnets to steer the beam particles.
Some Large Particle Accelerators:
- Large Hadron Collider (LHC) –
- Most powerful accelerator
- Location – CERN (Geneva)
- Significant achievements – Discovery of Higgs Boson, previously unknown hadrons etc.
- European Synchrotron Radiation Facility (ESRF) –
- Home to most intense hard x-ray source in the world
- Location – France
- Stanford Linear Accelerator Centre (SLAC) –
- Longest linear particle accelerator in the world
- Location – USA
- Significant achievements – discovery of quark and tau leptons.
Significance of Particle Accelerators:
- Fundamental research – Studies on colliding sub-nuclear particles near speed of light, New particles and forces, origins of universe etc.
- Health – Sterilizing medical equipment and synthesis of radiopharmaceuticals for cancer diagnosis and its therapy.
- Environment – Trace and detect chemical elements in air, water or soil.
- Industry – Improving materials durability
