Nat. complex laser fusion reactions
"Create a small star in the world" - this is the goal of National complex laser fusion reactions (NIF), which is the largest with the most powerful laser energy content, which is located in Livermore, California. September 29, 2010 NIF completed the first experiment on the ignition, in which 192 laser focused on a small cylinder with a capsule with frozen hydrogen fuel. This experiment was the latest in a series of tests that will lead to the long-awaited "ignition", when the nuclei of the atoms in the fuel capsule forced to merge, releasing tremendous energy. It is expected that the yield of fusion energy at the facility for the first time exceed the energy spent to start the reaction. It will be a valuable source of strength. The construction of NIF took more than 3, 5 billion in 1997, the complex is part of the Lawrence Livermore National Laboratory. Lawrence. Complete fusion scientists want to achieve by 2012.

1. National complex laser fusion reactions dovozit elevator technicians to target chamber for inspection. The chamber is a balloon of 10 meters in diameter, assembled from aluminum panels 10 cm thick. It is covered with 3-meter layer of concrete impregnated with boron to absorb neutrons from the fusion reaction. Holes 192 in the chamber allow laser beams to enter the camera. (NIF / Lawrence Livermore National Laboratory)
2. The largest single item of equipment at the National complex laser fusion reactions - 130-tonne target chamber. Its design consists of 6 symmetric panels of medium size and 12 asymmetric outer panels that are poured on an aluminum plant in Reyvensvude, West Virginia. The panels were transferred to «Creusot-Loire Industries» in France, where they are heated and shaped like an enormous pressure. Then the panel was sent to «Precision Components Corp.» in York, Pennsylvania, where the welds were made. Then, the assembly was made the target chamber at Lawrence Livermore National Laboratory.

7. Branch of laser №2. The laser beam is doing more than 304 meters, and then reaches the target chamber. Office laser №2 was commissioned on 31 July 2007. (NIF / Lawrence Livermore National Laboratory)
8. Production of fused glass tiles laser amplifier, necessary for the construction of NIF (3072 pieces) was completed in 2005. Tiles amplifier is a phosphate glass, blurred neodymium produced by «Hoya Corporation USA and Schott Glass Technologies». (NIF / Lawrence Livermore National Laboratory)
9. Techniques Livermore National Laboratory. Lawrence John Hollis (right) and Jim McElroy set a target camera in office in January 2009. This camera is the latest from 6206 of various opto-mechanical and controls system modules, which are called "exchangeable linear units." It was established September 26, 2001. (NIF / Lawrence Livermore National Laboratory)
10. NIF necessary optics, produced from the large single crystal of potassium dihydrogen phosphate and deuterated potassium dihydrogen phosphate. Each crystal is cut into 40-cm crystal panel. Traditionally, deuterated potassium dihydrogen phosphate is produced by, for almost two years that it was necessary to grow a single crystal. Over time, this time is reduced to two months. As a result of this process produced the optics to 66 cm wide, 50 cm in height and weighing 380 kg. Necessary optics 192 NIF produced from conventional deuterated potassium dihydrogen phosphate, and 480 from the optics of potassium dihydrogen phosphate. About 75 crystals will be able to achieve the weight almost 100 tonnes. (NIF / Lawrence Livermore National Laboratory)

A tiny capsule will be filled with a liquid mixture of deuterium and tritium, which will be frozen to -255 degrees Celsius. Then, the laser beam 192 enter the cavity, creating X-rays which will heat the capsule to a temperature close to the temperature of sun.
