A place colder than the universe

The most powerful physics experiment in history, the particle accelerator Large Hadron Collider, is fast turning into one of the coldest places in the universe, in an attempt to recreate conditions after the Big Bang.

The most powerful physics experiment in history, the particle accelerator Large Hadron Collider, is fast turning into one of the coldest places in the universe, in an attempt to recreate conditions after the Big Bang. 

CERN laboratories in the border between France and Switzerland have entered the last stages Downlink temperature particle accelerator Large Hadron Collider (LHC) at 1.9 degrees Kelvin (-271 degrees Celsius), temperatures colder than the cosmic space away , 
BBC informs. 

The huge tunnel or underground LHC was equipped with thousands of magnets, arranged in a ring lying on the 27 kilometers, which will be maintained in these conditions by using chilly liquid heli. If everything goes perfectly, the cooling process would take about two weeks. 

Currently, six of the eight sectors of the LHC between 4.5 and 1.9 Kelvin, though all the machines were down to 1.9 Kelvin at a time in recent months. 
By comparison, the temperature in remote regions of the universe is around 2.7 degrees Kelvin (-270 degrees Celsius). 

To obtain high magnetic fields without consuming too much energy was necessary for the magnets to be "Superconductor", ie have the property (shown by some materials at very low temperatures) to channel electrical current with zero resistance and very little loss of energy, explains Roberto Saban, responsible for hardware division. 

Helios show spectacular properties at 2.2 Kelvin (about -271 degrees Celsius), becoming "superlichid", which allows directed heat very quickly and be a highly efficient cooling. 

LHC magnets must be subjected to examination and electric in the next few weeks to test their ability to face an intensity of up to 12,000 amps. Each sector of the accelerator particle contains about 200 electrical circuits and circuits can include up to 154 magnets or only one. When the particle accelerator will be started, will run at five trillion electron-volts, and then will be turned off during the winter, so the magnets can be taught with energies of seven trillion electron-volts. 

Also, before the LHC is switched on for the first time, beams of protons must be loaded with high energies in a chain of particle accelerators called "burner". 

Once the machine is cold, operators will inject beams in the main ring in opposite directions, strecurandu them through every sector of the LHC, with a speed close to that of light, until they close the circle. At preset points along the tunnel, the beams will collide with one another disaster force, and a timing system will be used for sectors to behave like a single device. 

The scientists hope to discover in November fragment among these particles collision, which provide clues about the birth of the universe.
