The end of the world was nigh. What happened? The LHC at Cern

Still there, Slim Buddha ?

Yes, I am, and hope to be around for a while longer. I have a friend working on this in CERN. He is a physicist and specialises in something called cold fusion. However, he left Zürich a few weeks back and we haven't heard from him since. He was selected to work on this a few months back and was very excited. I hope he makes it back because I am working on a project and his involvement in October is critical.

Cold fusion has been a long project, not unlike the search for the holy grail. I here this tunnel is bigger than Dublin. Are you sure you're not sitting on top of it.

Maybe we'll all meet up in a parallel universe

Just had a thought.
What's the plural of universe ?
Does it not mean 'one version' by etymology ?

I think they use the term multiverse to define the potential conglomeration of multiple universes.

That said, surely if discovered those multiple universes would simply be described as the universe given that universe derives from universal, that is, all encompassing.

i'm wearing my CERN lanyard holding my work id. i'm such a geek!!!

was late into work cus was watching the first part on the internet.
(was pretty much an anti-climax!)

the place looks positively spiffy on the telly but i can assure you most of the place (and the control rooms up to a week ago or so) look like dishevelled warehouses!

oooh! That's cool! Best Google Logo in a long time!

Testing is up and running but they say it will be a few weeks before the first collision of protons.

According to France 24, the LHC is held up by electrical problems:

there were some at the start up earlier this month.

Anyone know any more?

Did anyone look at the LHC webcams, here. Views inside and outside the main building. Interesting...

I can't stop watching .

That is cool.

How fast does a black hole travel ? Have I time for lunch ?

The European Organization for Nuclear Research has revealed for the first time that a 30-tonne transformer that cools part of the collider broke, forcing physicists to stop using the particle collider just a day after starting it up last week.

A normal glitch or a weird and unpredicted effect of the massive energies that were used earlier during the test ...

The LHC Overheats !!

Quote :

According to reports, only a day after the first successful circulation of protons in the Large Hadron Collider (LHC) last week, operations at the world's largest particle accelerator had to be stopped due to a fault with a 30 tonne transformer used to cool part of the facility. The protons were not being accelerated at the time and there was no risk to safety at the LHC.

Rather than maintaining the equipment below the operational 2 Kelvin, the transformer glitch caused temperatures to rise to over 4 Kelvin (which is still cold, after all it is only 4 degrees above absolute zero - but it's not cold enough). The transformer failed after the successful anticlockwise circulation of protons on the evening of September 11th and rumours about LHC problems have only just been confirmed…

This was bound to be a frustrating problem for the LHC engineers, but in many respects it was inevitable. This is a facility more complex than any technology ever built; a 27 km ring of 1000 supercooled electromagnets, operating at a temperature colder than anything in the Universe, with 2000 separate power supplies and a vast number of synchronized detectors and sensors… it's little wonder the LHC may experience one or two technical hitches.

Transformer Glitch Halts LHC Operations

It is a very delicate machine in fairness.

Out for at least two months.

This is yet another delay amongst many - the last two I know of have involved the magnets.

Still no black hole for you 905. A massive helium leak last Friday in the tunnel and the whole thing is down until next Spring.

They'll never find the Higgs winos with that yoke now - we'll have to rely on Pamela.

Any chance the huge energies they used on testing it broke it

They have had repeated problems with the magnets over the past few years. Perhaps there is something wrong with a basic assumption about how they will behave at those temperatures?

The failures could be something to do with the scale of the thing itself - was anything ever built on this scale of detail and energy and complication and sensitivity before?

I'll have to have a closer look at it later though
