    Funnley enough it detects neutrinos, and by the looks of things there in a pool :eyebrow: :D

    Yeah I'm not entirely sure how it's supposed to work, but I do remember that it is essential that the water is as pure as humanly possible. That whole pool is filled with triple distilled water, and it's something like five times clearer than 'clean' tapwater - i.e. light penetrates five times deeper

    don't suppose you've got a link to that wallpaper have you ? 1280x1024 prefered but i'll take anything because it looks so damn good.

    This: http://www.ps.uci.edu/~superk/ should pretty much answer all your questions in more detail than you'd care to go into. Sorry to go OT

    Indeed:
    It's not for making pure water, it just requires incredibly pure water to get accurate readings of neutrino interactions

    Nothings blocked out. He's just using a smaller resolution on the second screen, so windows just shows the gap as black space.

    Yea, I know that now. Previously, I thought it was a chamber for distilling the water, but the website the information was taken from was pretty vague.

    You could also use heavy water.... apparently :D

    Don't even want to think about how long it would take to collect that much heavy water!

    (Heavy water, for those that don't know, is water made with deuterium or tritium instead of regular Hydrogen. These are radioactive isotopes of Hydrogen with, respectively, one or two extra neutrons in the core, making it heavier while chemically it's still H20)

    wow! i hadnt expected quite as much interest!

    yes, to all those who realised (both before and after my post :idea: ) it is a neutrino detector.

    nice link atomic! although i actuall got the pic from here, that site is great and has fairly understandable information about the Super-K detector/ neutrinos.
    They are in the boat because the are servicing the Photmultiplier tubes (PMTs) (which convert a low number of photons, ie very dim light, into an electrical current). The neutrinos (occasionally) interact with the pure water inside the detector and produce a relativistic (FAST!) electron, which causes soemthing called Cherenkov radiation (it 'emits' light). This is what the PMTs detect, and you can tell there has been a neutrino event.
    Thats somewhat oversimplified, but about right :D
