Large Hadron Collider (LHC)

The LHC consists of a 27-kilometre ring of superconducting magnets with a number of accelerating structures to boost the energy of the particles along the way.

ATLAS, CMS, ALICE and LHCb are LHC’s four main detectors. Three smaller detectors also exist in the LHC and are used for more specific research: TOTEM, MoEDAL and LHCf.

 

Data taking commenced in 2008, and permitted the discovery of the Higgs boson, which was announced on 4 July 2012 by ATLAS and CMS experiments.

A High-Luminosity upgrade is foreseen - details can be found here: http://hilumilhc.web.cern.ch/

LHC Status

Bit Preservation

“State of the art” bit preservation with regular scrubbing and migration to new media

Data

Stored at WLCG Tier0 with additional copies across WLCG Tier1 sites

Software

“Published” into CernVMFS

Use Cases

“Standard”

Audience

Re-use of data within the collaboration(s), sharing with the wider scientific community, Open Access releases

Value

Landmark discoveries already made; significant potential for future “BSM” discoveries

Uniqueness

Unique data sets (both pp and HI) being acquired now - ~2035. Probably unique until “FCC” (2035-2050?)

Resources

Computing resources via Resource Review Board

Issues

Effort within the experiments is hard to find

Outlook

On-going activity on analysis capture and reproducibility. Regular public releases (according to individual experiment policies) and “master classes”
