    I recall hitting numerous sections of the site that were protected. One was a log of superconducting magnet quenches. I guess that openness doesn't extend to embarrassing operational problems...

    well, they have the abstracts... you don't have to download the whole thing... but having read one abstract, i'm lost in the technical jargon, that large particle collider scientists write about without hesitation.

    "Abstract. The TOTEM Experiment will measure the total pp cross-section with the luminosity-independent method and study elastic and diffractive scattering at the LHC. To achieve optimum forward coverage for charged particles emitted by the pp collisions in the interaction point IP5, two tracking telescopes, T1 and T2, will be installed on each side in the pseudorapidity region 3.1 || 6.5, and Roman Pot stations will be placed at distances of ±147 m and ±220 m from IP5. Being an independent experiment but technically integrated into CMS, TOTEM will first operate in standalone mode to pursue its own physics programme and at a later stage together with CMS for a common physics programme. This article gives a description of the TOTEM apparatus and its performance."

    I am very much looking forward to what comes out of the LHC. It's been wonderful to watch its construction and that's only a fraction of the satisfaction its discoveries will provide.

    Come on, don't you remember the slashdot article [] about it?

    Twenty-seven kilometers of tunnel under ground
    Designed with mind to send protons around
    A circle that crosses through Switzerland and France
    Sixty nations contribute to scientific advance
    Two beams of protons swing round, through the ring they ride
    Til in the hearts of the detectors, theyre made to collide
    And all that energy packed in such a tiny bit of room
    Becomes mass, particles created from the vacuum
    And then

    LHCb sees where the antimatters gone
    ALICE looks at collisions of lead ions
    CMS and ATLAS are two of a kind
    Theyre looking for whatever new particles they can find.
    The LHC accelerates the protons and the lead
    And the things that it discovers will rock you in the head.

    Come on, let's drop some particle physics in the club!

    If anyone ever needs a reason to wallop copyright, let this quote from the article [] be that reason;

    Most copies of The Blue Book had vanished from the SLAC Library, and the librarians wanted to make it available electronically. But they ran into a snag: No one could figure out who owned the copyright, so there was no one to give permission to put it on the Web.
    "It's an orphan work," SLAC archivist Jean Deken told me Friday. The original publisher was bought by another, which was bought by another, and so on. Finally, with the help of an expert from Stanford Law School, librarian Abraham Wheeler tracked down the current owner of the copyright-which said that since it could not find any documentation on the book, it could not grant permission to reproduce it.

    I understand every word. Any experimental particle physicist does. I will conceed its not clearn to non-experts.

    However an important feature of a luminosity and diffractive phyics detector such as TOTEM is its coverage, ie at what angle it can go to. Therefor its pseudorapidy range (basically the angle it covers from the beam line) and the distances of the roman pots from CMS (and effecting the angular coverage of this part of the detector) are key peices of information. This is perhaps the most important thing to know about TOTEM.

    Isn't it funny that the entire LHC spec is 1.600 pages, while the OOXML documentation, as submitted by Microsoft, is a full 6.000 pages.
    Does this reflect a difference in complexity, or is it a sign of something else?

    The unit here is the "barn" = 10^-28 m^2.

    As in "you couldn't hit a barn with that thing"?

    Is this physicist humour?
