    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 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.

  3. Funny? by vainov · · Score: 5, Interesting

    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?
