LHC to end 2022 data-taking season two weeks early to save on electricity, among other measures.

A pressure gauge at the Large Hadron Collider's cryogenics, which take up more than half of the accelerator's electricity consumption.As energy prices spike as a result of Russia’s invasion of Ukraine, possibly causing a global economic downturn and stoking fears of rolling blackouts — especially in Europe — science laboratories are not being spared.

CERN has also developed plans with EDF for reduced power configurations, in case energy use needs to be limited further in the coming months. Smaller measures are being taken to reduce overall energy use on the CERN campus, including switching off street lighting at night and delaying the start of building heating by one week.CERN’s flagship machine, the 27-kilometre-long Large Hadron Collider, is a major electricity glutton, in large part because of its, the largest of its kind in the world.

The longer shutdowns will affect the scientists who rely on CERN’s other accelerators for their experiments. Those that were scheduled for the last two weeks of this year’s run will have to be postponed until next year, and the competition for the reduced beam time next year will be fiercer than usual, says Mnich. The total number of proton–proton collisions in the LHC will be lower than normal this year and next, but Mnich does not expect that to have a huge effect on the science.

DESY is in talks with the German government to seek extra funding to maintain operations, which are making important scientific contributions to areas that are essential to the future of Europe, such as the development of COVID-19 vaccines, battery technology and solar power, Leemans points out. But its managers are also preparing for the worst.
