CERN eyes more powerful particle collider

Europe's Geneva-based physics lab CERN said on Thursday that it was eyeing plans for a circular particle collider that would be seven times more powerful than the facility which discovered the famous "God particle."

 "The time has come to look even further ahead," the European Organization for Nuclear Research (CERN) announced.
In 2012, CERN's Large Hadron Collider (LHC) —  a giant lab housed in a 27-kilometre (17-mile) tunnel straddling the French-Swiss border — identified what is believed to be the Higgs boson, the long-sought maker of mass theorized in the 1960s.
The facility flushed out the so-called God particle by crashing proton beams at velocities near the speed of light. It went offline a year ago for an 18-month overhaul.
The LHC, completed in 2008, has "at least 20 more years" of life in it, the agency said.
However, the long time needed to build its successor — the LHC took a quarter of a century —  means that planning should start now.
It will launch a feasibility study next week for a so-called Future Circular Collider (FCC) with a circumference of 80 to 100 kilometres (50 to 60 miles).
The FCC would probably be located in the same area and may incorporate the LHC tunnel in its infrastructure, CERN said in a statement.
The LHC after its overhaul will see collision energies reach 14 teraelectron volts (TeV) but the FCC should be capable of reaching unprecedented smashups of around 100 TeV, CERN said.
The FCC study will run in parallel with an ongoing probe into an alternative design — an 80-kilometre (50-mile) straight collider dubbed the Compact Linear Collider (CLIC).
The two studies will examine the feasibility and costs and produce conceptual designs by 2018/2019, when the European-wide strategy on particle physics research is set to be updated.
The winner will be "a worthy successor to the LHC," CERN said.
"Such an accelerator would allow particle physics to push back the boundaries of knowledge even further," it claimed.
Targets could include supersymmetry, the notion that there are novel particles which mirror each known particle.
It could also help shed light on dark matter, which comprises most of the cosmos and whose existence is inferred from their impact on ordinary matter.
Some 300 scientists will meet at the University of Geneva from February 12-15 to kick off the five-year feasibility study for the FCC.
There is no way of knowing how much building the FCC would cost at this stage, CERN spokesman Arnaud Marsollier told AFP.
Conceived in the 1980s and approved in the 1990s, the LHC cost five billion francs ($5.6 billion) to build.
CERN aims to have enough information by the end of the decade to — along with its global partners — be able to decide which way to go, Marsollier said.

He acknowledged that any new project is certainly decades from completion.

Switzerland: CERN lab drops Facebook due to data concerns

Europe's physics lab CERN on Wednesday said it had stopped using a Facebook team-chat application because of concerns about handing over data to the US tech giant.

Switzerland: CERN lab drops Facebook due to data concerns

CERN said it wound up its Facebook Workplace account on January 31 after the US firm gave it the choice of either paying to use the service or sharing data. “Losing control of our data was unacceptable,” CERN said in a blog on January 28, confirmed to AFP by spokeswoman Anais Rassat on Wednesday.

CERN said it started using Workplace when it was offered the service for free in 2016. It said some 1,000 members of the CERN community had created accounts and there were around 150 active users each week.

“Reactions were not always positive. Many people preferred not to use a tool from a company that they did not trust in terms of data privacy,” the laboratory said.

CERN said its staff would now instead use two open-source chat services: Mattermost and Discourse.

CERN is home to the Large Hadron Collider (LHC) — a giant lab in a tunnel straddling the French-Swiss border that is the world's most powerful proton smasher.

Workplace is an enterprise-oriented version of Facebook that, instead of distracting workers, is intended to let them connect and collaborate.

It claims to have around three million paying users. Facebook has faced a series of privacy scandals in recent years, including over the hijacking of personal data on millions of users by a British consultancy developing voter profiles for Donald Trump's 2016 campaign.
