Research network infrastructure provided by AARNet enabled the Australian scientific community's contribution to the Higgs boson particle discovery.
Australian scientists participate in global high energy physics, advanced computing and accelerator science initiatives, including the ATLAS experiment at the Large Hadron Collider (LHC) at the CERN (European Organisation for Nuclear Research) laboratory in Geneva, Switzerland. Research networks such as AARNet provide the reliable high-performance particle physics research demands.
Physicists are recreating the conditions of the Universe just after the ‘Big Bang’. They are searching for new discoveries in the head-on collisions of protons of extraordinarily high energy and these discoveries will change our understanding of energy and matter. Following the discovery of the Higgs boson, data from the ATLAS experiment allows in-depth investigation of the boson’s properties and the origin of mass.
Data processing for some 500 trillion collisions at the LHC requires fast and reliable research networks spanning the globe with processing facilities distributed over those networks. The day never ends for the ATLAS experiment – it is a true global collaboration involving thousands of scientists from more than 177 universities and laboratories worldwide.
The Australian Research Council Centre of Excellence for Particle Physics (CoEPP) based at the University of Melbourne is Australia’s leading research centre in high-energy physics. The Centre is a collaborative research venture between the University of Melbourne, the University of Adelaide, the University of Sydney and Monash University.
Through its work on the ATLAS experiment at the LHC in CERN, CoEPP researchers contributed to the Higgs boson discovery in 2012 and provided valuable, and essential, resources to the Worldwide LHC Computing Grid (WLCG). The WLCG consists of 170 computing centres in 42 countries, linking up national and international grid infrastructures.
The mission of the WLCG project is to provide global computing resources to store, distribute and analyse the ~30 Petabytes (30 million Gigabytes) of data annually generated by the LHC. The CoEPP research computing team provides grid-connected storage and computing resources via its ATLAS Tier 2 grid site.
“It’s a very exciting time for physicists. The Higgs boson discovery is a milestone for the physics community, and for human understanding of the fundamental laws that govern the Universe. As scientific discoveries go, this is up there with finding a way to split the atom. Australian research groups have been part of this for the best part of 25 years,” says CoEPP Director Prof Geoffrey Taylor.
“The site’s high availability and reliability has been achieved as a direct consequence of the stellar performance of the underpinning network connectivity between the Australian Academic Research Network (AARNet) and corresponding WLCG Tier 1 site at TRIUMF (Canada’s national laboratory for particle and nuclear physics) across AARNet’s trans-Pacific SXTransPORT link. Sustained transfer rates of High Energy Physics data sets greater than 7Gbps between North America and Australia are not uncommon,” says Prof. Taylor.
AARNet provided CoEPP connectivity to the WLCG during the famous first run of the LHC and now for its second run, where even greater demands are placed on the underlying computing infrastructure. Dr Taylor says greater network bandwidths to Australia will be crucial in order for CoEPP to continue to provide meaningful contributions to the computational power needed for the physics analyses.
As CoEPP continues to achieve international recognition for Australia in the field of high-energy physics, its collaborative capacity and contribution to worldwide projects relies ever more on the capabilities of the networking infrastructure connecting Australian researchers and resources to the world.
The discovery of a Higgs boson particle has seen the international research effort shift focus to study its unique characteristics - and Australia’s Synchrotron is also playing a collaborative role with CERN.
The Synchrotron, Australia’s highest energy particle accelerator, which broke the world record for generating the ‘smallest, brightest, most intense electron beam’, is a test bed for the new technologies and techniques needed for the next phase of Higgs boson-related study. One of CERN’s technology experts, Dr Ralph Steinhagen, worked with researchers at the Synchrotron in Clayton on studies aimed at increasing the precision of measurements and control of particle beams. The work informed the 2013/2014 enhancement of the Large Hadron Collider.
As Australia’s national research network, AARNet facilitates high-capacity telecommunications connectivity across Australian universities and the international NREN communities to make international collaborations conducted by the Australian Synchrotron and the ARC Centre of Excellence for Particle Physics possible.
AARNET's reliable, fast and cost-effective research network has played a significant role in the success of the Australian site to deliver the storage and computing resources to the Large Hadron Collider's ATLAS experiment.”
