The world's largest particle accelerator may be forced to delay its plans to conduct the second, and most important phase of its project, after dealing with a series of problems.

First, there was the transformer that failed one day after the Large Hadron Collider conducted the successful test of the protons beam.

Now, it appears that the engineers at the Geneva laboratory are dealing with an unexpected failure of some of the magnets along the circular accelerator filled with liquid helium. Science Now reported a leakage of helium in the subterranean tunnel which might cause the next experiment to be delayed for weeks, until the problem is fixed.

In the first week of experiments, the LHC team managed to send beams around the ring in both directions, exceeding all expectations and giving great hope for the true experiment, when scientists will attempt to collide the two beams.

However, following the experiment, CERN reported the failure of a power transformer on one of the surface points of the LHC, which caused the main compressors of the cryogenics for two sectors of the machine to switch off.

Although they've managed to change the 30-tonne transformer over the weekend, and began re-cooling the magnets in preparation for the next beam experiment, yet another problem appeared.

Scientists will need to take their time to fix the helium leakage, since everything needs to go perfect when they will attempt to collide the two beams in the world's most exciting and hopefully rewarding experiment.
