LHC was restarted Friday after it was switched off last September, just nine days after start up, due to leakage of helium caused by electric fault.
Scientists are delighted with the progress being made by LHC. On Friday, the scientists had succeeded in firing beams of protons clockwise across the 17 mile particle accelerator located beneath the Franco-Swiss border near Geneva, Switzerland.
Accelerator speeds up proton beams
On Monday, as the experiment progressed further, the scientists also succeeded in smashing proton beams for the first time ever.
Scientists at CERN have confirmed that $10 billion LHC has used its accelerator Tuesday for speeding beams of Protons. It is the first time that the Bing Bang machine had used its accelerator to speed up proton beams.
James Gillies, spokesman for the CERN, said that this is a new step in the initial phase and it indicates smooth operations of LHC.
The first collision occurred at injection energy of 450 billion electron volts. Now the energy of Proton beams has been increased from 450 to 540 billion electron volts.
Proton collision to recreate Bing Bang conditions
The LHC is expected to run with more energy, at nearly 1.1 trillion electron volts, which is more that the energy of the Tevatron, currently the most powerful accelerator at Fermilab near Chicago.
As beams of protons travel in opposite direction, they will gain energy with every lap. The first real test for LHC will come early next year, when proton beams will collide with enormous energy to give insight into dark matter and recreate forces and conditions that existed when the universe was less than a trillionth of a second old.
Scientists will analyze the particles created as the result of collision and will start giving clues about the origin of the Universe.
LHC sees its first proton beam speed up
"However with the LHC, collision will occurs in front of attentive eyes."
No it won't.
As a Particle Physics student, I have written quite a few essays on the nature of particle detectors and accelerators, and this does not happen.
Within the LHC the Compact Muon Solenoid detector is the most likely of the detectors to detect the particles CERN has been aiming for. However due to the nature of such particle interactions these generally can not be seen, or in the case of a high energy particle collision are dangerous to humans present. As such much like many particle detectors, the scientists will not be able to see the particle collisions themselves but will see the aftermath (which in the cases of many particle detectors is a series of tracks created by the particle travelling through the detector). By checking these tracks the momentum of the particle can be calculated and thus their charges and mass aswell (E=MC^2).
Einsteins relativity equation is very important in these situations as the relativistic effects of C are higher as the particle travels closer to maximum theoretical velocity (3x10^8ms). Due to the collider being designed for collisions at (1.4x 10^12 Electron Volts) the velocity will come very close to this theoretical maximum.Probably within a disparity margin of around 0.0000009% I'd say
Ek=(1/2MV^2)/r
F=BqV
these two equations are very important in this type of experiment and allow the calculation of the charge and the mass of a given particle, based on the voltage it was accelerated by and the radius of it's Cyclotron.
The first shows the Kintetic Energy of the given particle (in Joules).
The second shows the force exerted on it (in Newtons)
"many of high energetic rays enters the atmosphere every day... And I'm still here to finish my post."
If you are talking about gamma rays and such they are not nearly as harmful as those energy levels in the LHC due to the wave polarisation caused by gases in the Earth's atmosphere (Like O3)
What's a bunch of
What's a bunch of absurdities.
[Yet because of those ‘ad hominem’ campaigns, serious scientists trying to alert mankind can no longer publish in mainstream magazines]
Only peer review decide what can stand on the ring of the science... There is no conspiracy. But how to convince a paranoid not to be paranoid :)
And about dangerous-high-energies-particles-that-will-kill-us, many of high energetic rays enters the atmosphere every day... And I'm still here to finish my post.
However with the LHC, collision will occurs in front of attentive eyes.
Turn, turn around little protons ! :)
