I have found great amusement in the give-and-take of scientific minds involved in this “race for the Boson”.
Maybe Obama himself could help his European friends and provide a little “stimulus” package to buff out the potholes. Come on over, it’s a free show!

Wilfred: John is right. By the time the lead ions get into the LHC, all the 82 electrons will have been removed, leaving only lead nuclei. These nucleus-nucleus collisions will have 82 times the energy of the protons. The energy is a bit less concentrated than in the proton collisions but the purpose is to study more extended volumes (still extremelay tiny by normal standards) of VERY hot matter, the so-called quark-gluon plasma.

Here’s hoping that Obama will be setting aside some funds for the International Linear Collider, rather than consider a new SCSC. It’d be pointless to compete to be first to the Higgs+. Better to collaberate and get more bang for the buck.

Wilfred: when they do heavy ion collisions, my understanding is that they are fully ionized. (I could be wrong…)

[...] Een heliumgekoelde magneet in de LHCDe Large Hadron Collider, de grootste deeltjesversneller ter wereld van CERN bij Genève, gaat vermoedelijk september dit jaar weer van start. Aldus een bericht van de directie van CERN dat gisteren de wereld in werd geslingerd. September wil men eerst rustig proefdraaien en kijken of alles goed gaat en in oktober moeten de eerste echte botsingen tussen de protonen plaatsvinden. Zoals bekend kreeg de LHC op 19 september 2008 te maken met een ernstige heliumlekkage, 9 dagen na de opening. Sinds die tijd zijn technici druk bezig de schade aan sector 3-4 van de tunnelbuis te repareren, apparatuur te vervangen én last but not least te voorkomen dat een dergelijke lekkage zich in de toekomst weer voordoet. Mmmm, lijkt mij wel handig ja. De LHC zou overigens volgens een eerdere planning al in juli van start gaan, maar door allerlei strengere veiligheidseisen en de daaruit volgende noodzakelijke handelingen is die datum naar september verschoven. In 2010 hoopt men de eerste wetenschappelijke resultaten te kunnen melden. Nou, afwachten maar weer. Bron: Cosmic Variance. [...]

will there be just one electron kicked of the Pb atom and accelerated
or do they try to kick off more electrons so that acceleration is faster
if it is faster ?

on those enegy levels, is it still true that a bigger rock makes bigger waves?….one PB atom makes more debree that a cloud of protons?

You’ll note that our technology is not sufficiently advanced, because it can be distinguished from a rigged demo.

This seems reasonable.. as long as it doesn’t slip too much. the biggest
concern is that things don’t go *horribly awry* again of course, so as
long as there is some not crazy amount of delay, and we do start getting
some collisions this year, i think the large majority of physicists and
physics fans around the world will feel all was worth the delay… I profoundly hope.

Ciaobella, physicists simply work together better at ski resorts. Haven’t you ever noticed the reduced friction there?

Because that’s where the EUROPEAN organization CERN wanted to have it.

Why does CERN host this workshop at Chamonix (a ski resort town in the French Alps) rather than, oh I don’t know, maybe hosting it at CERN?
