CTOnews.com, Nov. 29 (Xinhua) there are only two accelerators capable of producing 10 billion electron volt beams in the United States, and each accelerator is about 1.90 miles (3 kilometers) long.

The electronic diagnostic device includes an air chamber, a dipole magnet and two scintillation screens DRZ1 and DRZ2. The whole device is placed in a vacuum chamber. Lasers and electron beams propagate from right to left. TAU Systems recently built a super-compact particle accelerator that can reach a beam of 10 billion electron volts in length of 10 centimeters (4 inches).

TAU has built a helium-filled chamber in a laboratory environment, but it still needs a huge laser to guide it.

TAU uses a Texas kilowatt laser at the High Energy density Science Center at the University of Texas at Austin, which sits on a 10-meter (34-foot) long table.

Texas kilowatt lasers emit ultra-powerful lasers at an energy level of 1000 times the installed capacity of the United States, but they can only be emitted once an hour and last only 150 femtoseconds, or 1/1000000000 of the lightning discharge time.

TAU built the entire test equipment, no more than 20 meters (66 feet) long, and then emitted a 10-GeV beam.

The 532 nm laser is focused on the surface of the metal plate through the top window, and the nanoparticles are produced by laser ablation. A conventional particle accelerator is actually a series of rings that can attract electrons when a positive voltage is applied to these rings. These rings are powered up sequentially, pulling electrons through the tunnel faster and faster, and closing all rings before the electrons reach the tunnel.

However, laser-driven wake accelerators more or less turn the light pulse itself into a plasma wave, causing particles to chase it and collect extraordinary speed and energy over very short distances.

TAU's equipment uses a small chamber filled with helium. When a Petawatt laser emits light pulses through this gas, the huge energy of the pulse ionizes the gas into a plasma. As it passes through the plasma, the pulse leaves a wake behind it, just like a ship leaving in the water-except in this case, it produces extremely strong charge fluctuations.
