Anyone who doesn't take truth seriously in small matters cannot be trusted with large ones either by Albert Einstein.
Re: ** Current Events and discussion **
Just checked in, looks like 3+ hours of both beams at 3.5TeV and holding! Looking good for a big event! (but no detectors are switched on yet)

Have the beams crossed path yet? but without the detectors on?jmayes wrote:Just checked in, looks like 3+ hours of both beams at 3.5TeV and holding! Looking good for a big event! (but no detectors are switched on yet)
Re: ** Current Events and discussion **
There are magnets to keep the beams apart in the experiments but so far they have not been used so there could have been collisions but since they have only 1 bunch in each beam and are keeping them out of sync with each other it was unlikely.Wallmott wrote:Have the beams crossed path yet? but without the detectors on?

Beams have not been made to collide at 7 TeV but expected collisions was announced officially today http://press.web.cern.ch/press/PressRel ... 6.10E.html (Champagne!)Wallmott wrote:Have the beams crossed path yet? but without the detectors on?jmayes wrote:Just checked in, looks like 3+ hours of both beams at 3.5TeV and holding!

It better work at 9:00 AM CERN time as they have live satellite feed booked http://press.web.cern.ch/press/lhc-firs ... /schedule/ lol
I think the detectors are on to collect whatever events occur (cosmics, Beam on particles in the vacuum, collimator and beam scraping) just to try and analyse as many events as possible to do calibration on the detectors before the fire hose of events actual collisions at high energy and luminosity produce. For example this CMS DAQ display http://cmsdoc.cern.ch/cmscc/cmstv/cmstv ... frames=yes has the instrument set to Physics on Random on and Calibcyc on. which I believe means they are trying to capture what ever event may occur for whatever reason. I would think the other experiments are doing this too.
