Vacuum Leaks Lead To Another LHC Delay 224

Posted by Soulskill

suraj.sun tips this story at ZDNet about a new problem with the LHC. Quoting: "The restart of the Large Hadron Collider has been pushed back further, following the discovery of vacuum leaks in two sectors of the experiment. The world's largest particle collider is now unlikely to restart before mid-November, according to a CERN press statement. The project had been expected to start again in October. To repair the leaks, which are from the helium circuit into the insulating vacuum, sectors 8-1 and 2-3 will have to be warmed from 80K to room temperature. Adjacent sub-sectors will act as 'floats,' while the remainder of the surrounding sectors will be kept at 80K, CERN said in the statement. The repair work will not have an impact on the vacuum in the beam pipe. CERN has pushed back the restart a number of times, as repair work has continued. To begin with, scientists said the LHC experiment would restart in April 2009. In May, CERN [said] that the restarted experiment could run through the winter to make up some of the lost time."

          You could leak matter *into* the vacuum....like some sort of crazy reverse-leak! That's it! The LHC is designed to manufacture anti-leak!

            You laugh but that is exactly what a vacuum leak is. Air or some other gas leaks in and ruins the vacuum. Happens in auto engines causing performance problems there too. In the LHC they need a really good vacuum so that those hadrons can get up to a high speed which they won't do if they collide with gas molecules.

      The story or the development process?

    • Maybe history is repeating itself, if the first test they did caused some sort of temporal loop at the atomic level and that's what's been causing all the subsequent problems.

        What, how many times? Dozens? Hundreds? You mean I've been working at the same job for over a century now, but only got about one year's worth of paychecks?! To hell with black holes destroying the Earth, that's nothing compared to this!

      I understand this being /. most people think that argh is just a pirate term, since there are so many RIAA stories. In the context of Physics, which is what this post is about, argh is an SI unit of work done incorrectly.

    I had a vacuum leak once and in less than 5 seconds my house, instead of just smelling like dog hair smelled like stale month old dog hair in a vacuum bag. I also learned to empty the bag more often.

  • I'll take the "over" bet on this one. It will not restart successfully until after June 1, 2010.

    For an experiment of such magnitude, a delay of a few years is not very important...it's way more important to make the experiment in a good way, above anything else.

      No worries though, he has a crowbar [reddit.com] now.

        That's so awesome. Someone actually sent them a crowbar and CERN played along. Well, my last concern (that there were no crowbars at CERN for Gordon to use) is finally assuaged.

    To paraphrase, this guy is in the middle of a flooding city. He repeatedly refuses attempts of others to rescue him, claiming God will save him. He drowns, winds up in Heaven, and asks God why he didn't save him. "I sent you a two boats and a helicopter..."

    So I can see God now using his mighty and flagellant tendrils to tinker with the LHC's inner workings and yet we still press on, thwarting his every attempt to save the planet Earth and the life he created. I'm certain this will all end with a, "Okay, power it up!", followed by a surprisingly brief sucking sound as the world is drawn into a black hole of its own making.

    I can just see the look on his face...

  • Vacuum leaks? There's vacuum leaking OUT of the LHC?

    Holy crap! If this continues that monster could leak enough vacuum to completely cover the entire world, possibly destroying all life on Earth. How long are these madmen going to keep playing with dangerous things like vacuum before somebody puts a stop to it all?

    Think about what it takes to work on that thing. It's in a long underground tunnel of rather small diameter for what's in there. Fixing stuff in place is difficult and hazardous. Removing a magnet involves disconnecting everything (a big deal; some of the connections are welded and superconducting), lifting the magnet onto a narrow carrier that runs on the walkway (no idea how that's actually done) and inching the carrier for kilometers to one of the two big vertical shafts where it can be hoisted out vertically. As an underground maintenance job, this is not fun.

    The canceled American SSC was designed with a larger tunnel diameter. The LHC was designed with the assumption that not much magnet maintenance would be required, which cut costs but turned out to be a bad assumption.
