In assoluta controtendenza rispetto alle allarmistiche cassandre per il diffondersi dell’influenza H1N1, Michel Bussien and Erik Sjödin vi propongono INFLU: il collettore di virus influenzali, per accrescere deliberatamente il vostro rischio di contagio. Attenzione: INFLU è sconsigliato a tutti i soggetti a rischio: persone di età superiore ai 65 anni, bambini sotto i 5 anni, donne incinte, e persone con situazioni sanitarie croniche.

Today the LHC circulated two beams simultaneously for the first time, allowing the operators to test the synchronization of the beams and giving the experiments their first chance to look for proton-proton collisions. With just one bunch of particles circulating in each direction, the beams can be made to cross in up to two places in the ring. From early in the afternoon, the beams were made to cross at points 1 and 5, home to the ATLAS and CMS detectors, both of which were on the look out for collisions. Later, beams crossed at points 2 and 8, ALICE and LHCb.

After almost one year from the first 3 laps of protons in the Large Hadron Collider before a quench of a superconducting magnet damaged the accelerator seriously, protons come back in the LHC! And in a much less fanfared fashion.
Here the first press release:
During the last weekend (23-25 October) particles have once again entered the LHC after the one-year break that followed the incident of September 2008.
Friday afternoon a first beam of ions entered the LHC clockwise beam pipe through the TI2 transfer line. The beam was successfully guided through the ALICE detector until point 3 where it was dumped.
During the late evening on Friday, the first beam of protons also entered the LHC clockwise ring and travelled until point 3. In the afternoon of Saturday, protons travelled from the SPS through the TI8 transfer line and the LHCb experiment, until point 7 where they were dumped.
All settings and parameters showed a perfect functioning of the machine, which is preparing for its first circulating beam in the coming weeks.
Here a plan of the commissioning schedule; I’m looking forward for the first physics run!

Last year they started to commission LHC (Large Hadron Collider). What’s the status now?
At the moment they are cooling it down.
