Only Sectors 3-4 and 6-7 are still in the cooling phase (currently between 60 and 20 K). As already mentioned in the previous update, as soon as a sector reaches the nominal cryogenic temperature, teams can start powering the magnets. At present, the current is flowing in the magnets of three sectors, while the remaining three will be powered in the coming two weeks.

The new layer of the Quench Detection System (QDS), installed in four sectors, is functioning well.
The LHC commissioning team had taken advantage of a suspension of beam operation to test the magnets at a high current of more than 9000 amps. These essential electrical tests began in June 2007 and all the other sectors passed with flying colours. This was the last circuit of the last sector to be tested, making its failure all the more frustrating.

Is the hadron Collider being stopped by breakdowns, from the future, to keep the Higgs particle from being detected?!
--Several very distinguished scientists think so!
Dr. Nielsen is well-qualified in this tradition. He is known in physics as one of the founders of string theory and a deep and original thinker, “one of those extremely smart people that is willing to chase crazy ideas pretty far,” in the words of Sean Carroll, a Caltech physicist and author of a coming book about time, “From Eternity to Here.”
I found this on twitter, then the New York Times science article.
Then it will be time to test one of the most bizarre and revolutionary theories in science. I’m not talking about extra dimensions of space-time, dark matter or even black holes that eat the Earth. No, I’m talking about the notion that the troubled collider is being sabotaged by its own future. A pair of otherwise distinguished physicists have suggested that the hypothesized Higgs boson, which physicists hope to produce with the collider, might be so abhorrent to nature that its creation would ripple backward through time and stop the collider before it could make one,
