Beams of protons have spun round the 27-kilometre ring of the world's most powerful particle accelerator for the first time in three years.
The Large Hadron Collider, located under a Swiss-French border area near Geneva, is perhaps best known for helping to confirm the subatomic Higgs boson in 2012.
After planned maintenance and upgrades to let scientists and engineers from around the world make it even more powerful, it has been turned back on and will shortly start another run of cutting-edge physics experiments.
The European Organisation for Nuclear Research, or Cern, said that two beams of protons circulated in opposite directions around the accelerator on Friday, but high-intensity, high-energy collisions are still a couple of months away.
It is the collider’s third run. A first round of experiments took place from 2010 to 2012, and a second from 2015 to 2018. This round is expected to last until 2026.
The head of Cern’s beams department, Rhodri Jones, said: “These beams circulated at injection energy and contained a relatively small number of protons.
“High-intensity, high-energy collisions are a couple of months away.
“But first beams represent the successful restart of the accelerator after all the hard work of the long shutdown.”
As part of the international effort, UK teams have been involved in helping to improve the performance of each of the LHC’s four main instruments.
The UK’s contributions to the upgrade are worth more than £25 million, funded by the Science and Technology Facilities Council.
Professor Mark Thomson, the executive chairman of the STFC and a particle physicist, said: “The UK continues to enjoy a strong and fruitful relationship with Cern.
“Our scientists and engineers have played pivotal roles in contributing to the major upgrades, paving the way for exciting UK-led research on the more powerful beams at the LHC.
“It will never cease to impress me how our scientists and engineers, with their incredible skill and expertise, can continue to improve these cutting-edge facilities using evermore innovative technologies.
“The global science community will now eagerly await the results from the new run, which will probe some of the recent hints of new physics seen at the LHC and elsewhere.”
While pilot beams circulated in the LHC for a short time in October 2021, the beams that circulated on Friday mark not only the end of the second long shutdown for the LHC, but also the beginning of preparations for four years of physics data taking, which is expected to start this summer.
This third run of the LHC will see the machine’s experiments collecting data from collisions not only at record energy but also in unparalleled numbers.
Meanwhile, thanks to a major upgrade, Alice — a specialised detector for studying heavy-ion collisions — can expect a 50-times increase in the total number of recorded ion collisions.
The unprecedented number of collisions will allow international teams of physicists at Cern and across the world to study the Higgs boson in great detail and put the standard model of particle physics and its various extensions to the most stringent tests yet.
Tearful appearance
Chancellor Rachel Reeves set markets on edge as she appeared visibly distraught in parliament on Wednesday.
Legislative setbacks for the government have blown a new hole in the budgetary calculations at a time when the deficit is stubbornly large and the economy is struggling to grow.
She appeared with Keir Starmer on Thursday and the pair embraced, but he had failed to give her his backing as she cried a day earlier.
A spokesman said her upset demeanour was due to a personal matter.

Haircare resolutions 2021
From Beirut and Amman to London and now Dubai, hairstylist George Massoud has seen the same mistakes made by customers all over the world. In the chair or at-home hair care, here are the resolutions he wishes his customers would make for the year ahead.
1. 'I will seek consultation from professionals'
You may know what you want, but are you sure it’s going to suit you? Haircare professionals can tell you what will work best with your skin tone, hair texture and lifestyle.
2. 'I will tell my hairdresser when I’m not happy'
Massoud says it’s better to offer constructive criticism to work on in the future. Your hairdresser will learn, and you may discover how to communicate exactly what you want more effectively the next time.
3. ‘I will treat my hair better out of the chair’
Damage control is a big part of most hairstylists’ work right now, but it can be avoided. Steer clear of over-colouring at home, try and pursue one hair brand at a time and never, ever use a straightener on still drying hair, pleads Massoud.

The smuggler
Eldarir had arrived at JFK in January 2020 with three suitcases, containing goods he valued at $300, when he was directed to a search area.
Officers found 41 gold artefacts among the bags, including amulets from a funerary set which prepared the deceased for the afterlife.
Also found was a cartouche of a Ptolemaic king on a relief that was originally part of a royal building or temple.
The largest single group of items found in Eldarir’s cases were 400 shabtis, or figurines.
Khouli conviction
Khouli smuggled items into the US by making false declarations to customs about the country of origin and value of the items.
According to Immigration and Customs Enforcement, he provided “false provenances which stated that [two] Egyptian antiquities were part of a collection assembled by Khouli's father in Israel in the 1960s” when in fact “Khouli acquired the Egyptian antiquities from other dealers”.
He was sentenced to one year of probation, six months of home confinement and 200 hours of community service in 2012 after admitting buying and smuggling Egyptian antiquities, including coffins, funerary boats and limestone figures.
For sale
A number of other items said to come from the collection of Ezeldeen Taha Eldarir are currently or recently for sale.
Their provenance is described in near identical terms as the British Museum shabti: bought from Salahaddin Sirmali, "authenticated and appraised" by Hossen Rashed, then imported to the US in 1948.
