Uncover the secret of the universe when LHC 're-exported'

The giant particle accelerator (LHC) for the first time accelerated the speed of firing proton beams, sparking human hope in an effort to discover the origin of the universe, from November 24.

The universe was formed after the Big Bang, but we have not really understood how and why the universe has developed as it is today. And can LHC be the answer to these questions?

The energy of proton beams increased by 20%, from 450 billion eV to volt to 540 billion electron volts. This is good news for the scientific community after a long time of overcoming electrical problems, making LHC 'covered' nearly a year after only 9 days of operation.

Impressive re-export

On the evening of November 20, scientists quickly succeeded in launching the LHC and conducting the first experiment on this $ 10 billion machine after 14 months of troubleshooting.

The launch took place faster than expected when the proton beam was fired clockwise and about two hours later, scientists fired another beam anticlockwise with the goal of starting reactivate and recreate the Big Bang explosion through collisions between protons.

The movement of proton streams is a remarkable success. Scientists say this is an important milestone on the road towards scientific discoveries with this giant machine. According to James Gillies, a spokesman for CERN, this is a preliminary test, but things are going smoothly.

The LHC carries the responsibility of helping humanity learn about the origin of the universe. Scientists hope to test for two beams of protons moving in opposite directions in the accelerator colliding at speeds close to the speed of light that can reproduce at a small scale "Big Bang" ( Big Bang) created the universe 13.7 billion years ago.

Beams of proton particles fired are supported by a system of 1,600 superconducting magnet rods (with bars up to 15m long). According to experts, the energy of the proton beam, though increased to 540 billion eV, is still impervious to the realization of the ambition of the scientific world, to explore the formation of the universe.

According to CERN, after this initial success, expected in the first half of 2010, scientists will increase this index to 1.2 trillion eV, making the LHC the world's most powerful machine, surpassing the Tevatron at Fermilab near Chicago (USA), currently operates at 1 trillion eV.

Experts predict the mysteries of the universe will gradually open after LHC increases the energy of the proton beams to 3.5 trillion eV. The long-term goal set for this machine is 7 trillion eV. Expected LHC life expectancy is 15 years.

'Start bad'

This is one of the biggest human experiments ever. Scientists from the European Nuclear Research Organization (CERN) have worked hard to study and the LHC, a multi-billion dollar machine designed to "uncover the veil of secret" about the origin of the universe .

Thousands of the world's leading physicists have spent nearly 20 years completing this machine. LHC was built in an underground complex on the border between France and Switzerland. The machine was activated on September 10, 2008 and became a major scientific event of the world. But only a few days later, on September 19, it had to cease operation due to a large leak of helium.

The LHC machine is located at a depth of 100 meters below the ground.The proton pipeline is 27km long.

During the first test run, with 120 powerful electromagnets operating at -271.3 degrees Celsius, CERN physicists successfully shot 33 beams of proton particles clockwise and then in the direction vice versa in a 27km long pipeline of LHC.

But only 48 hours later, the first incident happened with a transformer weighing 30 tons and for replacement it took several days. On September 19, the LHC was started for the second time, but this time the wire between the two electromagnets failed, causing liquid helium leakage into the tube of the accelerator. So the waiting days in the fragile hope begin.

Some information about LHC:

- Location: A tunnel located at a depth of 100 m below the ground, 27 km long in the border area between France and Switzerland.
- Total value: 10 billion USD.
- Repair cost: 40 million USD.
- First start: September 10, 2008.
- Number of scientists involved in manufacturing: more than 8,000 people.
