LHC Running Again After Outage

The Large Hadron Collider (LHC) is back up and running again after a brief power outage due to a faulty electrical cable.  The power outage did not affect the LHC’s supercooled magnet system, but it did shut down CERN’s main computer system in addition to the equipment that injects beams of protons into the LHC’s underground ring.  The power outage come just a few days after the LHC set the record for proton acceleration.

LHC Achieves First Particle Collisions

Restarted this past weekend, CERN announced yesterday that physicists used the Large Hadron Collider (LHC) to smash protons together for the first time.  The collision occurred at low energy with each proton beam supplying 450 billion electron volts (GeV) creating a total of 900 GeV.  The next stage for the LHC will be to accelerate the proton beams to 1.2 teraelectron volts (TeV) each and collide the beam’s protons.  If achieved, this would be the highest energy level yet achieved by any particle accelerator.  European Organisation for Nuclear Research (CERN) expects this next stage to occur sometime in the next few days before a planned winter break.

After over a year of repairs the European Organization for Nuclear Research (CERN) has announced that the Large Hadron Collider (LHC) is expected to restart this weekend.  The restart has been delayed several times.  The last delay was due to problems with the LHC’s magnets.  The Large Hadron Collider was built by CERN with the intention of testing a variety of predictions within physics.  Such predictions include the existence of the hypothesized Higgs boson.

The restart of the Large Hadron Collider (LHC) will be delayed again.   The restart has been pushed back from October to November.    The LHC has been having problems with its magnets.  The magnets were trained to generate seven trillion electron volts, but have only been producing approximately four trillion volts.  The delay is necessary to determine at what energy level the LHC can run.  For more information, see ZDNet.

The world’s largest atom smasher will likely be restarted in October after further tests and safety precautions are put into place.  The LHC was to be restarted in September, but will be delayed 2-3 weeks.  The LHC was initially started on September 10, 2008, but was shut down 9 days later due to faulty wiring.  Once it is up and running again, it will start smashing hydrogen atoms together in order to better understand how the makeup of the universe.  For more information, check out the LHC website.
