The Large Hadron Collider (LHC) is set for a lengthy shutdown for upgrades. This isn’t the end for the famous atom smasher, but it does mark a significant pause in its groundbreaking work.
Located in a 16-mile tunnel near the Swiss-French border, the LHC imitates the extreme conditions of the universe shortly after the Big Bang. It accelerates particles to nearly the speed of light, where physics behaves in ways that often baffle scientists. This machine played a major role in one of the biggest scientific achievements: discovering the Higgs boson in 2012, a particle that gives mass to other particles.
In June, engineers will begin significant upgrades to the LHC, allowing it to conduct ten times as many particle collisions. This means scientists can perform many more experiments and gather even more data. The upgrades, known as the high-luminosity LHC project, will take about five years to complete. Despite this downtime, scientists will have plenty of data to analyze during the upgrade, according to Mark Thomson, the new director general of CERN.
Thomson, who has a background in experimental particle physics, expressed excitement about the upgrade. He noted that “the machine is running brilliantly,” and that there will be ongoing physics results to analyze.
The LHC won’t resume operations until around 2030. During this time, CERN is also considering a successor called the Future Circular Collider (FCC). The FCC would span 56 miles, vastly larger than the LHC. This ambitious project, expected to cost around $19 billion, raises questions about the future of particle physics. Some experts wonder if massive colliders are the best way to explore complex topics like dark matter and dark energy.
Despite uncertainties surrounding the FCC, Thomson believes in the importance of these large projects. He stated, “Our goal is to understand the universe at its most fundamental level, and this is absolutely not the time to give up.”
Recent data from the American Physical Society shows a growing interest in particle physics, with a 15% increase in publications related to the field over the past five years. This reflects the ongoing fascination and potential for discoveries that the LHC and its successors may yield.
In summary, while the LHC will be offline for a significant period, the excitement around its future and the exploration of our universe remains vibrant. The work done in this time will set the stage for even more groundbreaking discoveries.
