I ran my own blog from November 2006 till October 2014. All posts are still online, but I don't have time to update it anymore. Please note that all images and media files have been removed when the backup was moved to a new host in early 2016. Enjoy!
Today at about 13:00 local time scientists at the world's largest particle accelerator LHC first managed to collide beams at 7 TeV, which marks the official launch of the LHC programme at CERN in Geneva, Switzerland. Only ten days ago they managed to circulate two 3.5 TeV proton beams in the large 27 km ring, which already marked a new world record.
All collision detectors seem to work fine now, after the LHC experienced major technical problems during the past few years and the entire experiment had to be delayed on several occasions.
Scientists are now increasing up the number of collisions, although it may take months or even years until one can expect first publications about the results of the experiments.
