Boffins grasp Big Knob, get ready to go ALL THE WAY at the LHC proton-punisher

'Large HARDON Collider' headlines coming soon


Boffins at CERN are counting down the days until the rebuilt and now even more powerful Large Hadron Collider (LHC) particle accelerator restarts this spring, following a two-year-long shut down. Until this point, the LHC's power had been intentionally limited for safety reasons, but now its fullawesome power can be unleashed.

In that time, hundreds of engineers and technicians have been beavering away at repairs to allow the LHC to fire with nearly twice the energy of its previous run.

Among other things, they replaced 18 of the accelerator's 1,232 superconducting dipole magnets which steer particle beams around the LHC. Splices were also fitted into more than 10,000 electrical interconnections between the dipole magnets.

CERN said:

When the LHC restarts this year, the energy of particle collisions will be 13 TeV (or 6.5 TeV per beam) compared to 8 TeV (4 TeV per beam) in 2012.

This higher energy will allow physicists to extend their searches for new particles and to check previously untestable theories.

The machine has also been loaded with "new sets of radiation-resistant electronics" and the vacuum system that hoovers out stray molecules from the beam pipe has been revamped.

Techies at CERN, meanwhile, took advantage of the lengthy hiatus by installing almost 60,000 new cores and over 100 petabytes of additional disk storage to handle the beefed up data that's expected to flow from the experiments.

It will need to cope with the following deluge of information:

Bunches of protons in the accelerator will be separated in time by 25 nanoseconds compared to 50 nanoseconds. The LHC will thus deliver more particles per unit time, as well as more collisions, to the experiments.

To prepare for the challenges of more collisions, the LHC experiments, including ALICE, ATLAS, CMS and LHCb, underwent full consolidation and maintenance programmes, including upgrades to their subdetectors and data-acquisition systems.

All this anticipated activity could apparently lead to the discovery of a particle that is more exciting than the buzz created around the Higgs boson.

A top CERN researcher told the American Association for the Advancement of Science that the hunt was on for a supersymmetric particle to gift boffins with more clues about dark matter, the BBC reported. ®

The LHC's reawakening surely promises the return of headline gaffes such as this one. Bless.

  • Not enough desks and parking spots, wobbly Wi-Fi: Welcome back to the office, Tesla staff
    Don't worry, the tweetings will continue until morale improves

    Employees at Tesla suffered spotty Wi-Fi and struggled to find desks and parking spots when they were returned to work at the office following orders from CEO Elon Musk.

    Most tech companies are either following a hybrid work model or are still operating fully remotely. Musk, however, wants his automaker's staff back at the office working for at least 40 hours a week. Those who fail to return risk losing their jobs, he warned in an internal email earlier this month.

    "Everyone at Tesla is required to spend a minimum of 40 hours in the office per week. Moreover, the office must be where your actual colleagues are located, not some remote pseudo office. If you don't show up, we will assume you have resigned," he wrote.

  • LGBTQ+ folks warned of dating app extortion scams
    Uncle Sam tells of crooks exploiting Pride Month

    The FTC is warning members of the LGBTQ+ community about online extortion via dating apps such as Grindr and Feeld.

    According to the American watchdog, a common scam involves a fraudster posing as a potential romantic partner on one of the apps. The cybercriminal sends explicit of a stranger photos while posing as them, and asks for similar ones in return from the mark. If the victim sends photos, the extortionist demands a payment – usually in the form of gift cards – or threatens to share the photos on the chat to the victim's family members, friends, or employer.

    Such sextortion scams have been going on for years in one form or another, even attempting to hit Reg hacks, and has led to suicides.

  • 5G C-band rollout at US airports slowed over radio altimeter safety fears
    Well, they did say from July, now they really mean from July 2023

    America's aviation watchdog has said the rollout of 5G C-band coverage near US airports won't fully start until next year, delaying some travelers' access to better cellular broadband at crowded terminals.

    Acting FAA Administrator Billy Nolen said in a statement this month that its discussions with wireless carriers "have identified a path that will continue to enable aviation and 5G C-band wireless to safely co-exist."

    5G C-band operates between 3.7-3.98GHz, near the 4.2-4.4GHz band used by radio altimeters that are jolly useful for landing planes in limited visibility. There is or was a fear that these cellular signals, such as from cell towers close to airports, could bleed into the frequencies used by aircraft and cause radio altimeters to display an incorrect reading. C-band technology, which promises faster mobile broadband, was supposed to roll out nationwide on Verizon, AT&T and T-Mobile US's networks, but some deployments have been paused near airports due to these concerns.

  • IBM settles age discrimination case that sought top execs' emails
    Just days after being ordered to provide messages, Big Blue opts out of public trial

    Less than a week after IBM was ordered in an age discrimination lawsuit to produce internal emails in which its former CEO and former SVP of human resources discuss reducing the number of older workers, the IT giant chose to settle the case for an undisclosed sum rather than proceed to trial next month.

    The order, issued on June 9, in Schenfeld v. IBM, describes Exhibit 10, which "contains emails that discuss the effort taken by IBM to increase the number of 'millennial' employees."

    Plaintiff Eugene Schenfeld, who worked as an IBM research scientist when current CEO Arvind Krishna ran IBM's research group, sued IBM for age discrimination in November, 2018. His claim is one of many that followed a March 2018 report by ProPublica and Mother Jones about a concerted effort to de-age IBM and a 2020 finding by the US Equal Employment Opportunity Commission (EEOC) that IBM executives had directed managers to get rid of older workers to make room for younger ones.

  • FTC urged to probe Apple, Google for enabling ‘intense system of surveillance’
    Ad tracking poses a privacy and security risk in post-Roe America, lawmakers warn

    Democrat lawmakers want the FTC to investigate Apple and Google's online ad trackers, which they say amount to unfair and deceptive business practices and pose a privacy and security risk to people using the tech giants' mobile devices.

    US Senators Ron Wyden (D-OR), Elizabeth Warren (D-MA), and Cory Booker (D-NJ) and House Representative Sara Jacobs (D-CA) requested on Friday that the watchdog launch a probe into Apple and Google, hours before the US Supreme Court overturned Roe v. Wade, clearing the way for individual states to ban access to abortions. 

    In the days leading up to the court's action, some of these same lawmakers had also introduced data privacy bills, including a proposal that would make it illegal for data brokers to sell sensitive location and health information of individuals' medical treatment.

  • Behold this drone-dropping rifle with two-mile range
    Confuses rather than destroys unmanned aerials to better bring back intel, says Ukrainian designer

    What's said to be a Ukrainian-made long-range anti-drone rifle is one of the latest weapons to emerge from Russia's ongoing invasion of its neighbor.

    The Antidron KVS G-6 is manufactured by Kvertus Technology, in the western Ukraine region of Ivano-Frankivsk, whose capital of the same name has twice been subjected to Russian bombings during the war. Like other drone-dropping equipment, we're told it uses radio signals to interrupt control, remotely disabling them, and it reportedly has an impressive 3.5 km (2.17 miles) range.

    "We are not damaging the drone. With communication lost, it just loses coordination and doesn't know where to go. The drone lands where it is jammed, or can be carried away by the wind because it's uncontrollable,"  Kvertus' director of technology Yaroslav Filimonov said. Because the downed drones are unharmed, they give Ukrainian soldiers recovering them a wealth of potential intelligence, he added.
