LHC to skip low-energy test runs

[magnetar]

The Large Hadron Collider will not be ready in time to perform a low-energy "engineering run", which was originally scheduled to take place this November, according to an official at CERN. This will leave the operators no chance to gain experience with the particle accelerator's steering and detection systems before the high-energy runs begin in spring next year. The delay is due primarily to the failure of a Fermilab-built magnet during high-pressure tests in March.

The attempt to reach the full energy quickly lead to the magnet accident in 2008, leading to a delay of one year.
That doesn't mean it couldn't have happened with more time at lower energy, but it would have given more time to find the problem.
