Oh dear God Goth - I can't believe that.

I suppose we'd better load up a nuke to drop through the star gate when it forms!?

...and I seem to have missed the strangelets Meeko...


...woot woot...strange matter indeed :)

The following should be absolute requisite reading for everybody before internet forums based discussion of the LHC:

http://forums.somethingawful.com/showthread.php?threadid=2884322&userid=98756

Now, this picture is good.

http://void.printf.net/~conor/LHCb/cernschema.jpg

Linac = Linear Accelerator
Booster = Proton Synchrotron Booster
LEIR = Low Energy Ion Ring
AD = Antiproton Decelerator
ISOLDE = On-Line Isotope Mass Separator
n-ToF = Neutron time-of-flight mass spectrometer
PS = Proton Synchrotron

Protons start off in Linac 2, before they're accelerated into the proton sychrotron booster, and start getting accelerated progressively more in several stages of accelerators.

Along the way, some of the protons are tapped off for other CERN facilities. One of the first of those is ISOLDE.

The On-Line Isotope Mass Separator is a facility dedicated to the production of beams of a large variety of radioactive nuclides for a great number of different experiments, e.g. in the field of nuclear and atomic physics, solid-state physics, life sciences and material science. It does so by irradiating targets of different materials in the proton beam, and separating out the different product ions in the beam coming out.

Until now more than 600 isotopes of more than 60 elements (basically anything from helium to radium) have been produced with half-lives down to milliseconds and intensities up to 10^11 ions per second.

Now, the proton beam from the PS booster is injected into the Proton Synchrotron, where it is accelerated still further.

Now, there is also a beam of lead ions from linac 3 - since the lead nucleus has about 207 times the mass of a proton, made up of a whole bunch of protons and neutrons stuck together, interesting things are observed when they're collided.

These lead ions are accelerated (and stored) in LEIR first, before injection into the PS.

This observation of the collisions of heavy ions will be the purpose of the ALICE detector, and in many regards is similar to the functionality of the Relativistic Heavy Ion Collider in the US, which operates with gold ions.

Different kinds of particles are marked on this schematic map in different colours - light blue-grey for protons, dark grey for Pb ions, orange for neutrons, blue for neutrinos, and green for antiprotons.

A couple more experiments are tapped off the beamline after the PS - one of these is the Antiproton Decelerator. Protons are smashed into a target (the black bar that crosses the beam path on the schematic) and one of the product particles created (with a whole lot of other bits and pieces mixed in) is occasionally, an antiproton. The antiprotons are seperated with a magnetic spectrometer type of thing, and fed into the AD, where they're decelerated. It's neccessary to have very "cold", low energy, antiprotons for the antiproton experiments. The antiprotons are then used for a couple of interesting experiments where they are trapped in a magnetic trap and allowed to combine with a cold gas of positrons - forming anti-hydrogen atoms!

Next we shall consider the n-TOF experiment. Here, the protons are again driven into a spallation target, but here the goal is to produce neutrons - this is basically a neutron source.

http://www.news.com.au/story/0,23599,24317385-2,00.html

this is fucking rediculus both parts of this story

SCIENTISTS about to conduct one of the world's biggest physics experiments have received death threats amidst fears they could destroy the world.

The Large Hadron Collider (LHC), a giant particle accelerator built by European science organisation CERN, will start its atom-smashing activities tomorrow in an experiment it is hoped will uncover some of the secrets of the Big Bang.

CERN science writer Kate McAlpine created a YouTube hit with her rap music video explaining how the massive, underground LHC works.

Watch the "Large Hadron Rap" below for an explanation of what the accelerator does:



When the accelerator is fired up, two parallel beams of particles will be blasted around the underground ring in opposite directions.

At four locations on the circuit, superconducting magnets will bend the beams so that groups of protons smash into each other in a giant chamber rigged with equipment to record the collisions and their aftermath.

By doing this the LHC team hopes to recreate conditions similar to the Big Bang and find answers to some of the biggest questions in physics, such as how to explain mass, gravity and dark matter.

Despite the expected scientific benefits, some fear the experiment could create black holes that will eventually swallow the Earth. German chemist Professor Otto Rossler even led a last-ditch legal attempt to stop the experiment.

While recent studies have disproved the doomsday scenario, CERN scientists have reportedly received death threats and pleas to stop the experiment.

Professor Brian Cox of Manchester University told the British Telegraph newspaper that LHC scientists had been receiving threatening emails and phone calls demanding that the experiment be halted.

But Prof Cox, ex-keyboardist for 1980's pop group D:REAM, dismissed the hysteria in rock-star style.

"Anyone who thinks the LHC will destroy the world is a t---," he said.

The LHC experiment will be several times more powerful than anything else of its kind.

Scientists expect to find the theoretical Higgs-Boson Particle, or the God Particle, and gain a better understanding of things like antimatter, parallel universes and dark matter.

Meh, I bet the guys working on nuclear weapons had to put up with the same crap and they never did no harm. ;-)


So how long till they turn this thing on anyway?

Big claim, and completely ungrounded.

Science will never prove God exists or doesn't. Whatever God is, he may make himself evident within our existance through things science can understand, but is beyond that.

You will never, with science, be able to prove either way whether God exists.

You will also never be able to use God or religion to disprove something in science.

You know the coolest thing about science? They are just as excited at the possibility of not finding a Higgs Boson.

That just rocks.

Then it is important to note that God has the same "properties of existence" as the flying spaghetti monster, or Russel's Teapot.

So, what is it that people are really afraid of?

I'm not convinced that these people actually, honestly believe that the Large Hadron Collider will destroy the world.

So, what's the problem? It represents experimental physical science? It's a more visible target than COBE, or WMAP, or some argon atoms trapped inside bubbles in an igneous rock? It represents, physically and visibly, the study of physical cosmology, of the fundamental description of nature, you know? It represents the scientific truth of things like the Big Bang, it represents the fact that the universe is 13.73 billion years old, things like that? It represents the scientific fact that the book of Genesis isn't literally real , and it represents the people who will say that with a straight face? Is that what these people dislike?

In a manner of speaking, first particle injections occurred on the 8th of August with first attempt to run a beam through it happening tomorrow. And the "World Destroying" full energy collisions to take place some time later.

Oh right, so if science gets to the point where everything is discovered ever except god, it'd be because god is a crafty cunt?

You religious lunatics sure do like making sure there's little loopholes so your imaginary super best friends look legit.
