How does one give a tune up to a 27 Km particle accelerator?
Carefully?
Note the huge amount of data already collected is likely to keep people busy in analysis while this is going on.
The Large Hadron Collider (LHC) may have identified the Higgs Boson, but CERN knows the instrument can do better and today started the process of shutting down the massive machine, and the organisation's other particle accelerators, for a spot of maintenance. The key work, according to Simon Baird, deputy head of CERN's …
...the 2008 incident that crashed the facility...
"Crashed" is a bit of an understatement...how about "catastrophic failure"..? Afterall, crash implies a simple "Have you tried turning it off and on again?" might fix it - the 2008 incident involved replacement of considerable number of physical component and cryogas, and *then* it was "rebooted" then slowly re-frozen.
Well to me "crash" still implies its original meaning, the disk read/write head coming into contact with the platter. So in that case (depending in severity) it is not a simple matter of turn it off and on.
I assume you mean when a computer freezes through some form of memory conflict or some of the other causes of programs failing to run correctly and maybe freezing the OS with it.
So a crash is a catastrophic failure. So the article was correct.
Over at the Super Proton Synchrotron, meanwhile, 1o0 kilometres of radiation-damaged cables will be replaced
1. How f*ing cool is the name "Super Proton Synchrotron". Someone at CERN has been watching too many "Gerry Anderson" series...
2. Radiation damaged cables? How? And why 100km?
essentially the wires become damaged at the atomic level, resulting in instability when carrying mucho amps.
this can cause unexpected quenching in SC magnets due to Wigner induced heat release and directly by producing tiny gaps in the superconductors.
The only fix is to take the wires out and replace them, as there is no way to reverse the damage short of melting down the wires and reforming them..

Whatevere the views are there is one undenyable fact. THE L.H.C. opened the world of physics to the average person on the street. I, and a lot like me never gave phisics a second thought. The hole L.H.C. project instilled interest in a way rarely seen in a boring subject. Even when they got the power supply wrong and blew the L.H.C. up it gained peoples interest in the subject.
I take my hat off to them
Wake me up when they figure out that all motion in the third dimension is through the Higgs field with the process of neutral currents at the resolution of the Planck's dimension. In other words, all A-toms are replaced from the vacuum (Higgs Field) every Planck dimension and this process is so slow that nothing inside the third dimension can travel faster than light. Haven't worked out all the QED od QCD formulation yet, but I'm working on it.This includes Brownian motion as well. If you could control the Higgs field, theoretically, you could stop time in that field. If you could rearrange the Higgs field, you could travel from point a to point b in one Planck dimension. Some pretty serious stuff.
There is the theory which I invented :-) that the effect of Type 2 superconductivity is actually caused by Higgs bosons condensing within the lattice and releasing Cooper pairs.
This also neatly explains the current sensitivity (critical current) as there are a finite number of condensing Higgs's and when they run out the catalyst goes away and so does the superconductivity.
Also, moving Higgs bosons around might lead to a way to store energy in the very structure of a material. If you were to have a superconductor layered with a non superconductor then there would be a charge bias but the Higgs field itself would therefore be the (unlimited) energy source.
Obviously if you drew too much power and/or the whole thing warmed up too much the effect would break so you would need to keep it cold.
