So apparently an accident did happen during the start up test.
But a resonance cascade did not occur as we all were fearing.
An electrical malfunction caused a leak of sorts, of liquid helium in the acceleration tunnel. So now they have to heat up that section to ambient temperature and fix the problem, then re-cool it back down to near absolute zero. (as in minus 400 degrees or so)
This process is supposed to take 2 months.

Of course this could be a cover story.
