First proton collision in large particle accelerator

The European Nuclear Research Center (CERN) on November 23 reported the first collisions of proton beams in a large particle accelerator (LHC).

CERN General Manager Rollf Hoier said it was a big step in a short time.

A CERN scientist said that this could be the beginning of a marvelous era of physics and invention after 20 years of international community efforts to create unprecedented devices of complexity. and features.

The large particle accelerator was restarted on November 20 after more than 1 year of fixing a problem that caused the machine to be seriously damaged.

Currently proton beams are moving in the LHC - a 27km long tunnel, located at a depth of 100m below the ground at the border between France and Switzerland, at a speed of light (300,000 km / s).

The movement of proton beams is maintained by thousands of superconducting magnet rods.

It is expected that by January or February 2010, the energy of proton beams will reach 7 teraelectrovolt (Tev).

Then scientists will begin experiments, which can reproduce the conditions that existed about 13 billion years ago, after the time of Big Bang about 1-2 parts per thousand. billions of seconds, the explosion is said to have created the Universe.
