Quark fusion makes ten times as much energy as nuclear fusion

Scientists have overcome huge barriers in the past year to get us even closer to nuclear fusion, and with it a near-limitless supply of clean energy. But, what if there’s something far more powerful out there? According to researchers at Tel Aviv University and the University of Chicago, there is, and it involves the fusion of elementary particles known as quarks — the resulting energy from which would be ten times that of nuclear fusion. Quarks (not to be confused with the alien from Star Trek: Deep Space Nine) are tiny particles that make up the neutrons and protons inside atoms. They come in six different types, with scientists referring to them in terms of three pairs: up, down; charm, strange; and top, bottom. To find out more, researchers at the Large Hadron Collider (LHC) have been smashing atoms together at high speeds. Doing so, causes these component parts to split from their parent atoms, and fuse with other particles, creating baryons. Prior research has indicated that energy is produced when quarks bind together. By looking into one-such occurrence (a doubly-charmed baryon), the physicists found that it would take 130 megaelectronvolts (MeV) of energy to force two charm quarks together. On top of that, the fusion ends up releasing even more power, around 12 MeV. Motivated by their findings, they then focussed on the much-heavier bottom quarks. The same binding process, they claim, would theoretically release approximately 138 MeV, which is almost eight times as much as hydrogen fusion (which also powers hydrogen bombs). Naturally, this set off alarm bells, with the researchers hesitating to go public with their findings. “If I thought for a microsecond that this had any military applications, I would not have published it, ” professor Marek Karliner told Live Science . But, further calculations suggested that causing a chain reaction with quarks would be impossible — mainly because they don’t exist long enough to set each other off. Plus, there’s the fact that this type of bottom quark fusion is completely theoretical. Whereas, the researchers didn’t fuse bottom quarks themselves, they claim it is technically achievable at the LHC. Source: Nature

Large Hadron Collider crew has to pull 9,000 old cables

Even particle physics researchers have messes to clean up now and then. CERN has revealed to Motherboard that it’s pulling 9, 000 obsolete cables in three of the Large Hadron Collider’s injectors in order to make way for newer cabling. That’s a lot of work by itself (many of the cables are dozens of feet long), but it’s made all the more daunting by the consequences of yanking the wrong line. Since the cables are largely for control and safety systems, one wrong move could prevent the entire particle accelerator from working — try explaining that slip-up to your supervisors. The crew has already disconnected 2, 700 of the cables, and expects to remove all of them in 2017. CERN shouldn’t have any problems with the LHC shutdown scheduled for 2019, in other words. And hopefully, this won’t be necessary again. The gigantic amount of clutter stems from a “not-so-good habit” of leaving old cables around, which suggests that engineers will be much smarter about cleaning up in the future.
