Indian scientists have been involved in:

LHC - India:

• In the Construction of the Large Hadron Collider (LHC): Indian scientists have been involved in the design of many components of the LHC, whereas construction of those took place by scientists and engineers through Indian industries. Some of these components include superconducting corrector magnets, precision magnetic positioning system jacks, accelerator protection systems, quench detection electronics, vacuum system design for long beam transport lines and cryogenic systems.

ALICE - India:

• ALICE experiment: Indian scientists have played a significant role in the ALICE experiment, which is a dedicated experiment for search and study of Quark Gluon Plasma (QGP). Hardware contributions to the ALICE detector include the Photon Multiplicity Detector (PMD), the Muon Spectrometer, the MANAS chip, and Silicon pad detectors. The PMD is a fully Indian effort from conception to commissioning. The QGP research program of ALICE is on the quest to get a glimpse of how matter behaved within a few microseconds after the birth of our Universe. Indian scientists have contributed to the physics analysis, which led to the discovery of the QGP matter and its characterization.

CMS - India:

• CMS experiment: Indian scientists have played a major role in the CMS experiment, which is one of the two experiments that discovered the Higgs Boson. Our scientists have been involved in the design and manufactured the Hadron Barrel Outer Calorimeter; Silicon strip based pre-shower detector and RPC detectors, which are installed recently. Indian scientists have contributed to the physics analysis that led to the discovery of Higgs Boson and a detailed study of Quark-Gluon Plasma, a form of matter in the early Universe.

WLCG - India:

• GRID computing: Experiments at CERN produce colossal amounts of data (roughly 30 petabytes a year), which are processed using Grid computing, enabling sharing of resources belonging to computer centers located around the world. Indian scientists have contributed substantially to the building and operation of the Large Hadron Collider Grid (LCG). LCG has a hierarchical structure of data dissemination, of which India hosts two Tier 2 centres at Variable Energy Cyclotron Centre (VECC) and Tata Institute of Fundamental Research (TIFR), in addition to several Tier 3 centers. The two Tier-2 Grid computing centres at VECC and TIFR are performing large part of LHC computing.
