The final countdown?

Postby deja vu on Tue Sep 09, 2008 9:30 am

Should we be concerned when the world's largest subatomic particle
experiment is switched on in Geneva?

Mankind is either at the beginning of a great era of discovery, or it's
the end of the world.

On Wednesday, after 20 years of work by 10,000 scientists and engineers,
researchers start the hunt for the God particle, or the Higgs boson, which
could help explain the origin of mass in the universe.

When the switch is flicked at the Large Hadron Collider, the world's largest
particle physics laboratory, two beams of subatomic particles will be fired
around a circuit 17 miles long in opposite directions to smash into each other.

'Big Bang' experiment starts well

By Paul Rincon
Science reporter, BBC News

Scientists have hailed a successful switch-on for an enormous experiment which will recreate
the conditions a few moments after the Big Bang. They have fired a beam of particles called
protons around the 27km-long tunnel which houses the Large Hadron Collider (LHC).

The big test is weeks away. I guess the doomsday talk will just escalate now that the machine has
been turned on.

The universe is big It's vast and complicated and ridiculous and sometimes, very rarely
impossible things just happen and we call them miracles

Indian girl kills self over "Big Bang" fear: family

BHOPAL, India (Reuters) - A teenage girl in central India killed herself on Wednesday
after being traumatized by media reports that a "Big Bang" experiment in Europe could
bring about the end of the world, her father said.

The 16-year old girl from the state of Madhya Pradesh drank pesticide and was rushed
to the hospital but later died, police said.

So sad that it would affect anyone in this way.

Problems Stall Action for Collider

A week after subatomic particles began zooming around its underground racetrack to cheers
and Champagne toasts, the world’s most powerful particle accelerator, the Large Hadron
Collider, at CERN outside Geneva, is still struggling to take its next big step.

The scientists and engineers on the project had hoped that as early as late next week the collider
would actually begin to collide subatomic particles, though at energies far below the cataclysmic
levels that have had some skeptics worried about the creation of black holes that could eat the
world, a possibility that scientists dismiss as science fiction.

Collider halted until next year

The Large Hadron Collider near Geneva will be shut off until spring 2009 while engineers probe
a magnet failure.The incident on 19 September caused a tonne of liquid helium to leak out into
the experiment's 27km-long tunnel.

Officials said the time required to fully investigate the problem precluded a re-start before the
lab's winter maintenance period.

The collider is built to smash protons together at huge speeds, recreating conditions moments after
the Big Bang.

http://news.bbc.co.uk/2/hi/science/nature/7632408.stm

They finally turn it on and now its shut down for months. Huge disappointment for all those that
worked so hard on this. Hope this is the only issue they will face now and no more surprises pop up.

DOOMSDAY LAWSUIT DISMISSED

A federal judge in Hawaii today dismissed a lawsuit raising fears about Europe's Large Hadron Collider,
on the grounds that she had no jurisdiction over the multibillion-dollar project.

In a 26-page ruling, District Judge Helen Gillmor said that the world's largest particle-smasher was not
subject to U.S. environmental regulations because the federal government didn't contribute enough
money or play enough of a role in controlling the experiment.

After years of construction, the LHC was started up at low energy on Sept. 10, sending beams of protons
around a 17-mile-round (27-kilometer-round) ring of tunnels beneath the French-Swiss border. On the day
after the startup, however, the machine suffered a magnet malfunction, and more serious problems cropped
up a week later.

Collider 'needs warning system'

An official investigation into the accident at the Large Hadron Collider has recommended that an early warning
system be installed. This system would detect the early stages of a helium leak, following an incident that has
shut down the LHC until June 2009.

The collider is built to smash protons together at huge speeds, recreating conditions moments after the Big Bang.

Scientists hope it will shed light on fundamental questions in physics.

The report identified the uncontrolled release of one tonne of helium gas as the cause of damage to 53 superconducting
magnets. Better gas pressure release valves could avoid a repeat of the accident on 19 September, it says

Race for 'God particle' heats up

Cern is losing ground rapidly in the race to discover the elusive Higgs boson, its American rival claims.

Fermilab say the odds of their Tevatron accelerator finding it first are now 50-50 at worst, and up to 96% at best. Cern's Lyn Evans admitted the accident which will halt the $7bn Large Hadron Collider until September may cost them one of the biggest prizes in physics.

The two rivals are trying to identify the "God Particle" - one of the fundamental particles of matter. Finding the Higgs boson, whose existence has been predicted by theoretical physicists, might help to explain why matter has mass.

The chiefs of the world's most powerful atom smashers squared up at the American Association for the Advancement of Science (AAAS) annual meeting in Chicago.

The world's largest atom smasher will likely be fired up again in October after scientists have carried out tests and put in place further safety measures to prevent a repeat of the faults that sidelined the $10 billion machine shortly after startup last year, the operator said Saturday.

The Large Hadron Collider was meant to restart in late September, but that will probably be pushed back two to three weeks, a spokesman for the European Organization for Nuclear Research said.

"We're pretty confident about the dates," James Gillies told The Associated Press, adding that scientists believe they understand the error that happened last year and how to prevent it occurring again.

October will probably pass and no action.
It's hard to decide just where to begin

The Large Hadron Collider (LHC) experiment has once again become one of the coldest places in the Universe. All eight sectors of the LHC have now been cooled to their operating temperature of 1.9 kelvin (-271C; -456F) - colder than deep space. The large magnets that bend particle beams around the LHC are kept at this frigid temperature using liquid helium.

The magnets are arranged end-to-end in a 27km-long circular tunnel straddling the Franco-Swiss border. The cool-down is an important milestone ahead of the collider's scheduled re-start in the latter half of November.
