Sentences with phrase «plasma channels»

Previously, straight plasma channels have been used to produce those emissions, but all the emissions are projected forwards onto the same spot.
Each bullet becomes an intense concentration of electromagnetic energy that travels along a curved trajectory and leaves a bent plasma channel behind.
A current - conducting plasma channel forms as the air gets ionized along the laser beam.
Kasparian and Jean - Pierre Wolf, also at Geneva, are attempting to use plasma channels to control lightning strikes by firing laser pulses into thunderclouds.
Effects of plasma channels on ice formation or precipitation processes could not be proved in typical storm clouds, where ice crystals and subcooled water droplets coexist.
But Jérôme Kasparian at the University of Geneva in Switzerland, who was not involved in the study, thinks plasma channels produced by laser pulses could perform a more spectacular function on a larger scale.
Now, says SLAC's Spencer Gessner, the lead author of the new study, «We've engineered a hollow plasma channel — a tube of plasma with neutral gas on the inside.
Simultaneously, electrical discharges «drilled» thin plasma channels within the crust, producing other nuclear reactions and additional heat.
In 2004, Kasparian and Wolf took their plasma channel - generating laser equipment into thunderstorms in New Mexico.
They fired straight laser pulses into the thunderclouds 10 times every second, hoping that the high energy plasma channels that form in the laser pulse's wake would trigger lightning strikes, which would then travel along the plasma channels down to the ground, like a train running along railway tracks (Optics Express, DOI: 10.1364 / OE.16.005757).
It appeared that changing the thickness of the transparent plate affected not only the length of the plasma channel, but also the distance at which it arose.
They've ruined that but the University of Geneva, research is being done on sort of an amazing idea for being able to use lasers that would be directed, shot up into the sky into storm formations, that might have a lot electrical activity, basically creating a plasma channel to help guide the lightning down to a spot where you want it to hit so it's not just randomly hitting someplace else.
The energy needed for launching a spacecraft could be supplied to it from the ground through a plasma channel in the atmosphere.
One thought has been to shoot a pulsed laser into a cloud to draw out lightning in a storm and use the plasma channel formed in the laser's wake to guide the lightning away from homes and power lines.
These zircons and their contents probably formed in the plasma channels «drilled» by the electrical discharges at the beginning of the flood.
