DOE/Sandia National Laboratories A surprising effect created by a 19th century device called a Helmholz coil offers clues about how to achieve controlled nuclear fusion at Sandia National Laboratories' powerful Z machine. A Helmholz coil produces a magnetic field when electrified. In recent experiments, two Helmholz coils, installed to provide a secondary magnetic field to Z's huge one, unexpectedly altered and slowed the growth of the magneto-Rayleigh-Taylor instabilities, an...

App Combines Smartphones To Create Larger Display
2012-11-02 08:56:12

Lee Rannals for redOrbit.com — Your Universe Online A new display technology developed at the Tokyo University of Technology allows users to combine smartphones and tablets to create one large display with a pinch. The software allows users to place smartphones or tablets next to each other in any way they want, and then simply do a multi-gesture "pinch" motion to link the displays together and create a larger screen. The pinch motion is achieved by placing one finger on one...

Two remarkable pulsed-power machines used to test the nation's defenses against atomic weapons have surpassed milestones at Sandia National Laboratories: 4,000 firings, called 'shots,' on the Saturn accelerator and 9,000 shots on the HERMES III accelerator. Saturn – originally projected to last 5 to 10 years – began operating in 1987. Its major function has been to produce X-rays to test the effectiveness of countermeasures used to protect electronics and other materials...

More accurate simulations could lead to 'break-even' fusion in foreseeable future A new X-ray imaging capability has taken pictures of a critical instability at the heart of Sandia's huge Z accelerator. The effort may help remove a major impediment in the worldwide, multidecade, multibillion dollar effort to harness nuclear fusion to generate electrical power from sea water. "These are the first controlled measurements of the growth of magneto-Rayleigh-Taylor [MRT] instabilities" in fast...

Experiments in RFP fusion device show higher currents lead to self-organized helical plasma If you keep twisting a straight elastic string, at some moment it starts kinking in a wild way. Something similar occurs when one increases the electrical current flowing in a magnetized plasma doughnut: it takes on a wild helical shape, which spoils its performance. This phenomenon concerns scientists exploring fusion power, who use powerful magnetic fields to confine plasma during their experiments....
