back to article Higgs hunt halts as CERN prepares LHC upgrades

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 …

Wow

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.

Understatement

...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.

Re: Understatement

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.

WTF?

Re: Understatement

So, next time you "crash" your car into a bridge pillar at 70mph, just turn it (and yourself) off and back on again and then drive away like nothing's happened.

Super Proton Synchrotron

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?

Re: Super Proton Synchrotron

> Radiation damaged cables? How?

Read up on synchrotron radiation: when you use an electro-magnetic field to change the direction of charge particles (eg. protons) EM radiation is emitted. At the energy levels of CERN this is hard X-Rays.

Wigner effect

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..

The mentioning of the word "wigner" deservers an early Friday pint. Hope they have a quick way of replacing them or they'll have to be a lot of pints consumed. The clever buggers.

No.

This is gaffer tape, the magical fix-everything solution you're talking about here. Gaffer tape does not just "fall off."

Re: Higgs Hunt??

There are a couple of tentative observations of what might be a new boson, in the sort of mass range that some theories suggested the Higgs boson might be found in. There's a vast gulf between that and the existence of Higgs boson being a certainty and the existence of the Higgs field being proved and the whole issue of mass being neatly resolved.

"No new physics is a disaster for theoretical physics, they need clues as to how the Universe behaves beyond what we now have, to answer various maddening puzzles."

Like how many million toasted cheese sammiches the LH collider can fry per second at full power, or how many tons of beer it's cryogenics can cool per minute and still keep the collider running at full non steam.

Or can the beam be used to etch 3D graphics in the concrete tunnel walls....

Or ummmm can you really bore a hole through the center of the earth with it?

In spite of my liking for giving political types a good kicking this actually seems to be a pretty good example of collaboration! Anyway - what I really want is pics of the dial at 11.

I hear that Iran has released pictures of a dial that goes up to 12, although most analysts reckon they haven't actually got a synchrotron attached to it.

Educational

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.

Neutral Currents

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.

Re. neutral currents

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.
