LHC malfuntion

[Rhodes]

All that fuss about the LHC and in the second day of work, it malfunctions and stopped...

The news is in portuguese:

lhc ?


LHC ?

The Large Hadron Collider:

A transformer blew out during testing.

Thx Zayphod :D

[Digital_Trucker]

The Large Hardon Collider already malfunctioned. That didn't take long.:up:

[antikristuseke]

Given the complexity of the entire operation teething problems are to be expected, no huge engineering project is problem free.

The device is hugely complex. Remember these words:

"The more they overtake the plumbing, the easier it is to stop up the drain."
----- Lt Cmdr James Montgomery Scott, Chief Engineer, USS Enterprise

They've already replaced the broken piece, and are running it up again.

[Platapus]

I wonder how long it takes to bring that circular path down to close to Absolute Zero?

[antikristuseke]

According to CERN they are allready back at operating temperatures, but id imagine it takes about a week or so to reach optimum temperature levels after maintenance.

Wise words, as always, from the miracle worker!;)

Does anyone have a date that this malfunction that occurred on the 11th was first reported?

Some info on a new problem

[darius359au]

It's a 27km long machine with tolerances to the Millionth a Millimetre, operating at almost Absolute zero and they've only had a couple of failures ,That's not too bad ,But that's what this testing period is for before they start work - Finding the bugs:up:

[Rhodes]

Two month off-line!Well, a big thing, a big repair time... :lol:

It's actually a government cover-up. There was no transformer failure; the experiment accidentally opened a portal to another dimension and now aliens are invading!:roll:

In news they say that this one was the second malfuntion in the machine. I thought that the news was about the first one!

[Etienne]

Not surprising - as others have said, it's an insanely complex machine. I can't begin to comprehend everything that's involved in it, and I did 11th grade physics.

That's right! FEAR MY PHYSICS-FU!

Seriously, wasn't it in the testing phase, anyway? Stuff's gonna blow out, it's expected.

[Oberon]

D'oh! :damn:

Oh well, the Earth gets another two months to live, at least I'll get my holiday in November hopefully :up: ;) :lol:

From a guy I know in CERN

If you're looking for some inside news...

It was an incorrectly configured Web Application run on a private account on a CMS webserver that caused the security breach. All that could be done was overwrite an existing webpage with another. CERN ops systems are completely shielded from the internet. I think all the safety systems aren't even networked, so it's inconceivable to even damage the machines, leave alone destroy the planet.

Anyway, there was a big incident in the LHC this morning - it looks like a superconducting splice between two of the dipole magnets went bad, melted and a few tonnes of liquid helium boiled off This would have in turn caused a breach in the isolation vacuum (think the vacuum portion of a Thermos flask), so that entire sector (eighth of the ring) has to be warmed up for repairs. They think about two months or so.

That's just great, now I'll probably get sent in as part of the Opposing Force. :D

.... I think all the safety systems aren't even networked, ..... it looks like ...... They think ..
Those are not the kinds of words that look good coming from the "inside". I've seen way too many of those kinds of comments regarding the LHC.

I'm still wondering why it took a week for the first breakdown to become public.:hmm:

Their also taken out of context from the original post which was talking about the "Hacker" attack Not the LHC

Doesn't say anything like what was inferred does it? , all it says is that the hackers couldn't even get close to any of the systems , Not that there's No safety systems or CERN has no idea what's happening.

[Digital_Trucker]

If you look closely at the quotes from scientists in other reports, you'll also see those types of statements. Just an observation on my part, perhaps I'm the only one that sees it:hmm:

Edit :

"There seems to be no harm done. From what they can tell, it was someone making the point that CMS was hackable," said James Gillies, spokesman for Cern. "It was quickly detected."
Fortunately, only one file was damaged but one of the scientists firing off emails as the CMS team fought off the hackers said it was a "scary experience".
To refine security methods Cern set up a working group called Computing and Network Infrastructure for Controls. One document written by the group said: "Recent events show that computer security issues are becoming a serious problem also at Cern."
However, the team said yesterday that it did not want to comment on security at the international facility.



Still no explanation why it took a week to release the fact that the original breakdown had occurred.
