Restart of Large Hadron Collider now November

Large Hadron Collider (LHC)

(AP) -- Repairs to two small helium leaks in the world's largest atom smasher will delay the restart of the giant machine another month until November, a spokesman for the operator said Thursday.

James Gillies said an additional setback to the timing could result if some other problem is found, but the European Organization for Nuclear Research is taking pains to make sure it avoids another major shutdown like the electrical failure of Sept. 19.

"Essentially what's happening is we're proceeding with extreme caution," Gillies told The Associated Press. "We have to be absolutely certain that when we switch on this time, it stays switched on."

The organization, which is known as , has nearly finished examining the 10,000 electrical interconnections like the one that failed in September. Originally CERN said it expected to start test collisions in April, but that start up date has been pushed back several times already, most recently to October.

"Decisions will be taken as to whether there are more that need repairing or not within the next couple of weeks, and when we know that, we will be in a position to be a little bit more definitive about what we plan to do for the rest of the year," Gillies said.

If a November start holds, it will still take until December for the accelerator in a 17-mile (27-kilometer) circular tunnel under the Swiss-French border to start producing collisions of .

Only then will physicists be able to probe deeper into the makeup of matter.

They hope the fragments that come off the collisions will show on a tiny scale what happened one-trillionth of a second after the so-called , which many scientists theorize was the massive explosion that formed the universe. The theory holds that the universe was rapidly cooling at that stage and matter was changing quickly.

The leaks currently being repaired were found in the system that uses to bring the temperature inside the accelerator to near absolute zero, colder than outer space.

That low temperature makes it possible to use the massive superconducting electromagnets that control the beams of particles that will fly in both directions around the at near the speed of light until the scientists make them collide.

CERN expects repairs and additional safety systems to cost about 40 million Swiss francs ($37 million) over the course of several years, covered by the organization's budget. The overall project cost $10 billion.

RE-STARTING HLC WILL CONFIRM WHICH OPINION?

This is a bitter-sweet story for CERN and for the nuclear physics community. It will confirm that:

a.) HLC is based on a misunderstanding of the nucleus and the information recorded in rest masses of the 3,000 nuclei that comprise the entire visible universe:

b.) The Higgs boson - the imaginary God particle - and the validity of the Standard model in particle physics.

Flip that switch!

How many times has it broken, now? Oh, it's new equipment going through a teething period? Nothing like one of the most powerful machines in the world marginally under control.

When I think HLC, I don't think "great science", I think "incompetent and dangerous".

PUTTING MONEY ON THE ILLUSIONARY HIGGS BOSON

Dr. Manuel, you're ignoring the wave form turbulence model. We may validate the assumption that matter is an illusion. No one knows. But I certainly wouldn't put money on the Higgs Boson existing.


Yes, Velanarris, I purposely ignore models and look at experimental data like these:

Unfortunately, theoretical physicists ignore the data and all other hard evidence of a physical reality that falsifies the Standard Model of Particle Physics.

I am holding several Higgs Bosuns hostage in a warehouse somewhere downtown... Keep the LHC OFF if you ever want to see these Bosuns alive again!

Jul 31, 2009
First of all, I would like for all of you to recognize the picture representing the LHC, that's right- the ATLAS experiment. (In your face CMS!! ha.ha.ha)
Moreover, as a young experimentalist (working on ATLAS), who is interested in theory, I have investigated many of the facets (yet not completely) of the SM, specifically EW symmetry breaking.

It would seem that omatumr has not studied the theory in detail, like most of you. And claims that theorists are ignorant to some of the data which was released in 2001. Nonsense.
Moreover, dockknowledge, please refrain from being such an ignoramus on a science forum; you clearly have no idea how much work is required to build a functioning accelerator.
I would put my money on the discovery of *at least* one higgs boson by march. Anyone want to take the bet?

Your attitude is exactly what frightens me: there's a big button so we should push it. You don't reason, you don't consider the possible results of your action, you just want something to happen. You are a dangerous child.

I'm sure the Higgs boson does not exist but I am not sure it will prevent physicists from "discovering" it.

UNFORTUNATELY, YOU ARE RIGHT

We all tend to be greedy and to find what we are looking for.

The National Academy of Sciences uses those human weaknesses and directs research funds to "discoveries" that will promote NAS opinions - a Big Bang, dark matter, dark energy, the Standard Model of Particle Physics, the Standard Solar Model of a Hydrogen-filled Sun, stars and the cosmos made of Hydrogen and fueled by Hydrogen-fusion, Earth's climate is controlled by CO2, neutron - neutron interactions are attractive, etc. ad infinitum.

Hence the "discovery" that solar neutrinos oscillate before they get to our detectors, that neutron stars are dead nuclear embers, that Earth's climate is immune to cyclic changes in its heat source - the Sun - and the upcoming "discovery" of . . .

But the very spiritual foundations of science assure me that this house of cards will crumble: "Truth is victorious, never untruth" [Mundaka Upanishad 3.1.6; Qur'an 17.85].

That is why I say, "Flip the switch." Let's get the show started!

A security analysis was already conducted with considerations within the bounds of rationality. That's why you don't accept the results.

For example charge and magnetic momentum of black holes wasn't considered in estimation of speed/probability of their interaction with ordinary matter. While we know, EM force is 10^40 stronger, then gravity and most of black holes are charged magnetars.

I think a lot of you people use one of those random sentence generators with a dictionary of physics terms.
