Vacuum Leaks Lead To Another LHC Delay

suraj.sun tips this story at ZDNet about a new problem with the LHC. Quoting: "The restart of the Large Hadron Collider has been pushed back further, following the discovery of vacuum leaks in two sectors of the experiment. The world's largest particle collider is now unlikely to restart before mid-November, according to a CERN press statement. The project had been expected to start again in October. To repair the leaks, which are from the helium circuit into the insulating vacuum, sectors 8-1 and 2-3 will have to be warmed from 80K to room temperature. Adjacent sub-sectors will act as 'floats,' while the remainder of the surrounding sectors will be kept at 80K, CERN said in the statement. The repair work will not have an impact on the vacuum in the beam pipe. CERN has pushed back the restart a number of times, as repair work has continued. To begin with, scientists said the LHC experiment would restart in April 2009. In May, CERN [said] that the restarted experiment could run through the winter to make up some of the lost time."

Bit off more than they could chew

This is why movies have producers. It's to keep the artists in check. Someone should have kept the brains in check when they designed this thing. Instead of being smaller and useful, it's just a gigantic waste of money -- the Waterworld of the scientific community.

Once it 'works' . . . my guess is something will go wrong with the measuring instruments. There's no reason to think that the base functionality is the only thing flawed. It'll be great to finally have particles fire around the track, collide, and have bad data.
