ATLAS Alive!

Picture 1
In preparation for the upcoming first LHC collisions, ATLAS has started operating 24 hours a day, 7 days a week.  I have been on shift 7am to 3pm for the last 3 days.  The control room is full of activity as everyone is making sure we are ready (hopefully in about a month) for beam and then proton collisions in the LHC.
What we are doing now is recording data on muons created in cosmic-ray collisions in the atmosphere.  In the picture you can see a screenshot of a web page where you can go to see displays of the last 100 events collected by the ATLAS detector.
You can also see what’s happening in the ATLAS control room right now on the web cam (or the other one).

    Doesn’t the web cams bother you? I certainly wouldn’t want to have a web cam in my office.

    Not as much as the flash photography from the tour groups! And trying to ignore people who are staring at you from behind the visitor’s center glass 5 feet away takes a little effort. Did I mention the flashing red siren from the “simulated disaster scenario” exhibit which is a little distracting? All in the name of science…
    The web cam just updates a new picture once every few minutes so I don’t mind it. But from inside the CERN network, the web cams are actually video cameras and you can see people moving around in other control rooms. We use that sometimes to check if someone is in the satellite control room. It feels a little invasive.

    With thanks to Mel Brooks, “Alive! It’s alive! It’s alive!” ;-)

    The displays of the events collected by ALTAS are fascinating to me – and as a layman – almost completely unintelligible. Could you take one of the displays, or a series of them, and explain what the dots and lines represent? I assume all the dots are muons, but why are some in one section and some in another. Do you learn different things depending on where they appear on these images? And what you are ultimately looking for?

    Also, what is the geography of the detector itself, as we see it in these displays? And what are the information readouts on the lower right used for?

    Love your Blog – Any info at all would be greatly appreciated!
