CERN Releases Analysis of LHC Incident
sash writes "From the fresh press release: 'Investigations at CERN following a large helium leak into sector 3-4 of the Large Hadron Collider tunnel have confirmed that cause of the incident was a faulty electrical connection between two of the accelerator's magnets. This resulted in mechanical damage and release of helium from the magnet cold mass into the tunnel.
Proper safety procedures were in force, the safety systems performed as expected, and no one was put at risk. Sufficient spare components are in hand to ensure that the LHC is able to restart in 2009, and measures to prevent a similar incident in the future are being put in place.'"
It's too bad that projects like the LHC will soon run out of funding as bankrupt nations concentrate on keeping their populations fed and/or preventing the overthrow of their governments, rather than burning issues like "what is mass, really, when you get down to it?". Of course glitches and malfunctions like this (and the previous ones) will only serve to put us past the point of possibly having been able to answer that question, but failing due to lack of funding.
How many billions of Euros have been spent on this project already?

AFAIK, there's nothing terribly innovative about the accelerator or cryo portions of the LHC, apart from the scale of the thing.
The CEBAF in Virginia has been operating at 2 Kelvin since the mid-80s. The technology to operate an accelerator at Liquid Helium temperatures is mature and well-understood.
Odds are, this is a one-time design/construction hiccup. It's unfortunate that it happened, but should be something which can easily be overcome.

The LHC did destroy the universe. We're just in an alternate one where it failed instead.
