Ping : Ivan Reid

I see from the edition of Classic Bike that came out yesterday we had
a similarly misspent youth on GT380's.

Keep playing the sub atomic games of marbles

Ah, thanks, TOG said he'd tell me when it came out, but I believe
he's in parts forrn at the moment so he's excused.

We were supposed to be going for record intensity tonight. Ah, yes,

http://cmsdoc.cern.ch/cmscc/cmstv/cmstv.jsp?channel=1&frames=yes

The gobbledegook at the bottom means 25 bunches of protons in each
direction, with 16 bunches per turn colliding in each of the three major
interaction points (CMS, ATLAS - and ALICE I presume). That's still a ways to
go; 25 ns bunch separation=7.5 m; 27 km/7.5 m=3600 bunches; for operational
reasons they won't be all full, say 30-50% so we're at O(1%) final intensity.

I see so a bunch of particles going one way will hit a bunch of
particles going in the opposite direction and pretty photos wlll be
produced...

I can't handle anything more technical than a stickle brick being
attached to another stickle brick - thats why I own a BMW boxer.

Yep, there are two beamlines going around the ring, one beam in
one, t'other in t'other. At four "interaction points", where the
experiments are, the physical beamlines stop (there's an outer envelope
around all this of course, vacuum harder than the moon's surface and all
that...) and each beam crosses from one to the other, outside to inside
and reverse. And all the timing and control and whatnot means that the
bunches (should) collide in the centre of the four detectors.
