--------------------------
With 192 laser beams delivering over 2 megajoules of energy to target, the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory (LLNL) is the world's most energetic laser system and, for the first time in a controlled laboratory setting, has demonstrated fusion ignition and target gain greater than 1.  
The NIF generates ignition conditions by precisely firing the lasers onto a target comprising a centimeter-tall cylinder inside of which is a millimeter-scale spherical shell filled with deuterium-tritium fuel.  The fuel highly compresses, fusing the deuterium and tritium to release helium and large quantities of neutrons and energy.  A series of advances over the course of decades were required to reach this stage - laser optical components, target fabrication precision, and implosion design.  Building from here, the momentous demonstration of reproducible ignition paves the way for a new category of ignition science experiments as well as a broad array of materials and nuclear science studies within a novel regime of high energy density physics.

The speaker will be available to meet with interested students and postdocs after her colloquium, at ~15:15 in the cafeteria.

Stimulants available 15 minutes before the talk.
