THE ATLAS COLLABORATION 
AND THE TIER-1 DATA CENTRE 

ATLAS COMPUTING

ATLAS at CERN’s LHC, is one of the world’s largest scientific experiments. As part of the ATLAS-Canada collaboration, TRIUMF scientists, engineers, technicians, and students have provided critical expertise to the detector design, construction, installation, and data analysis for this global experiment.
Led by SFU and TRIUMF, the Canadian Tier-1 Data Centre provides large-scale storage and computing power to searches for advanced physics phenomena, like undiscovered particles or dark matter, and helps us grow our understanding of Universe.
Canada’s Tier-1 centre, supported by ten highly qualified TRIUMF staff, has performed with close to 100% up-time, supplying 10% percent of ATLAS’ global computational Tier-1 resources. Our Canadian centre contributed to the data reprocessing and modelling that enabled the 2012 confirmation of the discovery of the Higgs boson.

The original Tier-1 Data Centre was located at TRIUMF from 2007 to 2018, and was moved to a consolidated facility at SFU in 2019.

With the Hi-Luminosity (Hi-Lumi) upgrade, the LHC will restart in 2029, and be able to collide 10x more particles than its initial design value. More collisions means more data from rare events, including more Higgs bosons.

The TRIUMF-operated Tier-1 Data Centre will continue to provide infrastructure and user-support with room to grow as ATLAS prepares for the Hi-Lumi Era.
