Sentences with word «hohlraum»

Joining the Lab in 2002, Nathan Meezan quickly established himself as one of LLNL's experts in hohlraum physics and design for laser - driven targets, and was chosen to be the lead designer for the very important first implosion campaign on the NIF laser.
He championed this design, which has opened a whole new part of parameter space for hohlraums on NIF.
Their goal is to field the fibers as a capsule - support alternative to the «tents» traditionally used to hold the peppercorn - size capsules inside NIF hohlraums (see «How NIF Targets Work»).
This campaign studied hohlraum energetics and drive symmetry.
The ICF program is actively pursuing multiple hohlraum designs like the one put forward by Meezan.
He also was the lead author on the high - impact paper on the use of uranium hohlraums, which was essential to the success of these experiments.
Lepró helped pioneer the spinning of spider - silk - like yarns for use in suspending target capsules inside NIF hohlraums.
But they have since gone out for bids and it looks like [the hohlraums] are down to the order of a couple pennies each with a contract to do millions of them,» Sellman says.
For instance, the cost of the fingertip - size «hohlraum,» the target chamber or «oven» where deuterium and tritium fuel is cooked, was $ 10,000 each.
Two million joules of ultraviolet laser energy then converges on a cylindrical target called a hohlraum, after the German word for «cavity.»
The hohlraum is placed precisely in the centre of the chamber by a positioner (bottom right) before the lasers are switched on.
When the lasers strike the hohlraum, their energy is converted to X-rays that burn away the beryllium, compressing the fusion fuel.
The target is a gold - plated cylinder the size of a pencil eraser (8.4 millimetres by 4.6 millimetres), called a hohlraum.
This campaign leverages his expertise in hohlraums by using a new low - fill, near - vacuum hohlraum.
There, researchers are working to achieve fusion by using 192 laser beams in an approach known as indirect - drive, in which the laser light is first converted into x-rays in a gold enclosure called a hohlraum.
