Together with scientists from around the world, physicists at the MPP have developed and constructed the particle detector ATLAS. ATLAS is an experiment at the Large Hadron Collider (LHC), a particle accelerator at the CERN research center in Geneva. The LHC began operating in 2008. In March 2010, the research program got under way at this proton-proton accelerator, working with the highest energies achieved to date at any accelerator facility. With the help of the LHC, researchers from all over the world want to coax out the secrets of the structure of matter and the fundamental forces.
ATLAS records the results of proton-proton collisions produced by the LHC. In the process, conditions similar to those in the extremely early, hot and dense universe shortly after the Big Bang are created. From that, the researchers gain insights about the fundamental building blocks of matter as well as their interactions. They are looking for new phenomena, such as the existence of higher dimensions of space and time and the origin of the dark matter that holds our universe together.
The MPP was and is involved with the development of instruments essential to the ATLAS detector – the inner detector, the calorimeters, and the muon chambers – as well as the setup of the computing system. A major technical upgrade is scheduled to start from 2026. The goal is to increase the number of proton collisions in order to obtain more data. MPP scientists and technicians are working to make ATLAS fit for the coming surge of new data.
30 years of ATLAS
The history of the truly big experiment began on October 1, 1992, when close to 90 research instituitions signed a common letter of intent to build a detector for proton-proton collisions. The Max Planck Institute for Physics was one these, its scientists contributed to the devolopment of major ATLAS components.
The greatest success of the ATLAS experiment so far was the discovery of the Higgs boson in 2012. As early as the 1960s, the theoretical phycisitst Peter Higgs, François Englert and Robert Brouthad proposed the existence of this particle: As a building block of the Standard Model, it gives other elementary particles their mass. For this, Higgs and Englert received the 2013 Nobel Prize.
Since June 2015, the LHC accelerator has been running with a record energy of 13 teraelectronvolts – nearly twice as much as in the years before. With that, the researchers hope to discover "new physics" – that is, particles and effects that do not occur in the Standard Model but which could help to solve the puzzles of the dark matter, the dark energy, and the missing antimatter in the universe.
