B Is the Large Hadron Collider large?

  1. Sep 25, 2016 #1
    Or, is that that the hadrons are large? Or, are they both large? What exactly is the adjective "large" qualifying please? I do know that the tunnel is very large indeed, and that this is the most sophisticated machine ever built.

    So, you're guess is that this is a hadron collider, which is very large. As opposed to a hadron collider for large hadrons?

    Thanks for the response.

    I know (large hadron) colliders as heavy-ions-colliders.

    Most of the experiments involve protons, which are the smallest stable hadrons.

    That's not a guess, it's a historical fact about where the name came from.

    So, to clarify then: the collider is large, not the hadrons?

    Yes. Large hadrons, i.e. heavy ions are smashed in other facilities: Dubna, Darmstadt or Berkeley.

    The "Large" in Large Hadron Collider refers to the fact that the accelerator itself is very very big.

    The LHC also accelerates lead ions, which are indeed large hadrons, but that is not the "large" that the name refers to. (Also, in the parlance of physics, no-one calls ions "large", but "heavy", in general. The class of accelerators that accelerate heavy ions are "heavy ion accelerators").

    Which is a by no-means exhaustive list of heavy ion accelerators, also.

    No. Just the famous ones that created new elements.

    RIKEN (Japan) would beg to differ! They have the naming rights to Z=113. They're also at the forefront of new isotope discovery, outstripping pretty much everyone in the world at the moment.

    Yes - in fact, the biggest ever built.... 27 kilometers around, which would qualify as "large" even if weren't the biggest.... Not many human-built structures are larger.

    @Beanyboy, here are two short videos about the LHC:

    Really enjoyed watching those! Thanks ever so much.
