Re: Current Events Discussion

Nice indeed... lots of info to digest. I like the delivered luminosity vs. fill # graph on p. 14.

Re: Music

yeah, I saw the lhcsound site... what I've been doing is similar to what they call "sweeping the detector" - at least in how I read data from the ATLAS image.

Re: Music

I've been working on sonification of the atlas live display images. Here's a preliminary clip:

Re: Luminance, luminosity, squeezing explained in English

this article http://pdg2.lbl.gov/atlasblog/?p=339 explains cross-section as a probability that a sub-atomic event will occur: What the LHC has provided so far [article written April 5, 2010] … is on the order of hundred inverse micro-barns. This means that processes charcterized by production cross-...

Re: El Reg LHCb story

1993 article on B+ production in LEP:

http://cdsweb.cern.ch/record/257181/files/P00019894.pdf

Also, the recent LHCb article refers to "known B+ mass of 5.32 GeV," meaning the observed mass from prior experiments.

Re: 7E10 single injections

looks like they are alternating between physics fills (with squeeze studies) and high-intensity injection/dump studies. this physics fill intensities are edging up... the present fill is ~ 3E10. also, it looks like there is a lot of intensity loss in the squeeze studies, especially when they get dow...
