It turns out that CERN never reached max. power capacity last week.
There were several liquid helium leaks, and the experiments had to be stopped prematurely.
When the same problems re-occured the following days, CERN decided to do a proper repair.
Therefore the entire ring has to be warmed up to the surrounding temperature (which will take about 1.5 to 2 weeks), have the leaks repaired, and have the ring cooled down again to near zero Kelvin (which will take another 2 weeks again).
Total expected repair time is at least about a full month !
The same threat is still there : this could happen to all of us any time in the future : LOOK and SEE !!!
