The 48 bunch run broke the world record for stored energy in an accelerator

Well done guys

(The energy was 3.2 MJ in that 48 bunch run, by the way. A car of 1000 kg doing 120 kph on the highway is about .5 MJ, for comparison.)
Strange coincidence that right after this run was dumped (16:21 on friday), within the hour, cryo failed, cryo tripped while trying to fill again, then there was a power glitch during the ramp, which means that we have to wait for more than two days before we can run again. It is now Sunday 17:26...
Of course, this just shows how complicated everything is, and proves that it really is an achievement!

The good news is, that right after I posted that, the same night they broke the records again:
5.2 MJ in the machine (new world record), luminosity 9 Hertz per microbarn (new LHC record).
I pays off not to give up.

Good Stuff

And the good news keeps on coming. Recent fills have produced initial instantaneous luminosity of 30 inverse micro-barns per second.
The challenge is to quickly increase that to 150 (ub.s)-1 500% greater in order to meet projected 1 femtobarn (1000 picobarn = 1,000,000 nanobarn) goals by the end of 2011 run.

woohoo exciting times coming

Thanks Joe

Nice work guys

Nice work and fantastic firework

we could expect nice data for physic discovery

what about a wake up for Atlantis live display ??

If you see it's not updating during a run with stable beams, just send me a message. Address is in the source of the page.
