I have just gone through the press release from CERN. They said that investigations at CERN following a large helium leak into sector 3-4 of the Large Hadron Collider (LHC) tunnel have indicated that the most likely cause of the incident was a faulty electrical connection between two of the accelerator’s magnets. Before a full understanding of the incident can be established, however, the sector has to be brought to room temperature and the magnets involved opened up for inspection. This will take three to four weeks. Full details of this investigation will be made available once it is complete.

The time necessary for the investigation and repairs precludes a restart before CERN’s obligatory winter maintenance period, bringing the date for restart of the accelerator complex to early spring 2009. LHC beams will then follow.

Today is 10th september,2008 and LHC has started up. Beam is in the LHC now. So CERN is really hot. Two blogs have started live bloging to keep us updated – Cosmic Variance and symmetry breaking . You can also get updates in the blog of  Tommaso Dorigo. Here is the plan for tomorrow . Best of luck for LHC.

I have just visited Guardian’s Particle Physics section and found that they have really made a nice flash presentation of Cern’s Large Hadron Collider( LHC ) . Yes.. that Large Hadron Collider for which physicists are waiting for a long time and after 20 years of preparation it is ready to switch. This is the main focus now in science community. Does SUSY ( SuperSymmetry ) exist? Does extra dimension exist ? and more.. questions are to be answered by LHC. Here are two snap shot of Guardian’s presentation.
