Earth is fighting to stay alive. Mass dieoffs, triggered by anthropogenic assault and fallout of planetary defense systems offsetting the impact, could begin anytime!

LHC IS FAULTY

Posted by feww on March 10, 2010

Large Hadron Collider (LHC) Construction Flawed: Director

Dr Steve Myers LHC cannot be operated at full  potential for [at least] two years.

In September 2008 after about 100 of the LHC’s super-cooled magnets heated up to more than 100°C, the system was shut down. It took 14 months to repair.

Soon the machine must close down again for about a year to make the tunnel safe for high energy proton collisions.

“It’s something that, with a lot more resources and with a lot more manpower and quality control, possibly could have been avoided but I have difficulty in thinking that this is something that was a design error.” Myers said, BBC reported.

“The standard phrase is that the LHC is its own prototype. We are pushing technologies towards their limits.” He added.

“You don’t hear about the thousands or hundreds of thousands of other areas that have gone incredibly well. [REALLY?]

“With a machine like the LHC, you only build one and you only build it once.”

The $10 to $14 billion “White Elephant” is buried up to 100m below the French-Swiss border region.

LHC Champaign Science & Three-Legged Chickens!

Posted by feww on September 22, 2008

Will they ever catch the ‘wretched’ smashed particles?

For anyone following the fate of LHC, here’s a quick update.


The Large Hadron Collider (LHC) is shut down indefinitely for all intents and purposes. At least no particle smashing is likely to occur before the official inauguration on October 21, 2008.

In fact, the collider may not be fully operational before May 2009 due to huge power requirement.

The machine went out on September 19 with a [little] big bang when a “massive” magnet quench caused over 100 of its solenoid magnets to overheat from 1.9 Kelvin to at least 373K, or 100ºC (boiling point of water) and toasted the wiring. [Note: (K) = (°C) + 273.15]

And yes, the fire brigade were called to the rescue when the system vacuum failed and tons of liquid helium escaped into the 100-meter deep LHC tunnel.

[Note: The LHC tunnel has a 27-km circumference and is built underground at a depth ranging from 50 to 175 meters.]

CERN’s director of communications, James Gillies, wants the public to look at the latest spate of failures philosophically: It’s taken us 20 years to build the machine, and we were behind the 2006 completion date by errr… 2 years. Would a few more months or another year, even two, change the “big picture?” He asks.

[No worries, Mr Gillies, so long as you can tell us in this lifetime what the smashed particles looked like. Oh, and go easy on the bubbly stuff!]

To repair the machine, they’ll have to warm it up very slowly to the ambient temperature. After fixing, it has to be slowly cooled down again to its operating temperature of 1.9 Kelvin (about -271ºC).

A litany of “difficulties” and “serious difficulties” delayed both the construction of the tunnel and the collider machine. Like the three-legged chickens, the wretched smashed particles are proving too difficult to catch!

The Three-Legged Chickens!

On the lighter side of things, it’s been said that an Australian scientist held the patent to the three-legged chicken. The idea for genetically modified monster chickens came to her because everyone in her family (she, her spouse and son) liked to eat fried chicken legs. A curious scientist visiting the ranch downunder where the tripodal creatures lived wanted to know what they tasted like. The inventor replied: “I wish we knew. The wretched things run so fast we haven’t been able to catch one yet!”

Large Hadron Collider Crashes

Posted by feww on September 20, 2008

LHC Crashes, Fire Engines Called

Engineers hoping to smash particles at the Large Hadron Collider (LHC) were forced to stop work, after about 100 of the LHC’s super-cooled magnets heated up to more than 100°C.

The failure, called a quench, in this case a “massive” quench, occurred  in sector 3-4 of the accelerator, at a point between Alice and CMS detectors, at about 09:30UTC/GMT on September 19, 2008.

Tons of liquid helium leaked into the Collider’s 27-km tutunnel at Cern, near Geneva, Switzerland. Some 20 years after the construction began, and about $10 billion later, this was the second reported incident since last week which stopped work on the giant white elephant.

The quench occurred when liquid helium leaked out of the LHC’s cooling system which keeps the super-cooled magnets at 1.9ºK above absolute zero ( 0ºK is -273.15ºC). LHC engineers also reported a loss of vacuum condition in the cooling system.

A faulty transformer delayed work at LHC throughout last week, and was replaced only a day before the quench occurred.

Will Be Back in November, Possibly December!

CERN spokesperson,  James Gillies said the repairs would be expensive.

“A full investigation is still under way but the most likely cause seems to be a faulty electrical connection between two of the magnets which probably melted, leading to a mechanical failure.

“We’re investigating and we can’t really say more than that now.

“But we do know that we will have to warm the machine up, make the repair, cool it down, and that’s what brings you to two months of downtime for the LHC.”

Thought for the Day: The LHC and Earth

Posted by feww on September 9, 2008

Big Bang, Indeed! [Putting the Cart before …]

The good news: “We” are about to find some answers to how the universe was born [or so we hope!]

The Bad News: We have no idea how to stop killing the earth!
