COLLOQUIUM: Progress towards fusion on NIF and Z requires new plasma measurement capabilities

There is significant progress towards fusion on NIF and Z with alpha particle heating on NIF and modest neutron yields on Z. However future progress requires advances in measurement capabilities. Examples of high speed xray imaging, optical Thomson scattering, neutron imaging, time resolved neutron spectroscopy, time resolved x-ray spectroscopy, and gamma spectroscopy will be described.

 

A little drop will do it: Tiny grains of lithium can dramatically improve the performance of fusion plasmas

Scientists from General Atomics and the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) have discovered a phenomenon that helps them to improve fusion plasmas, a finding that may quicken the development of fusion energy. Together with a team of researchers from across the United States, the scientists found that when they injected tiny grains of lithium into a plasma undergoing a particular kind of turbulence then, under the right conditions, the temperature and pressure rose dramatically.

An improvement to the global standard for modeling fusion plasmas

The gold standard for modeling the behavior of fusion plasmas may have just gotten better. Mario Podestà, a staff physicist at the U.S. Department of Energy's Princeton Plasma Physics Laboratory (PPPL), has updated the worldwide computer program known as TRANSP to better simulate the interaction between energetic particles and instabilities – disturbances in plasma that can halt fusion reactions.
