Abstract

Inertial confinement fusion research at Los Alamos National Laboratory is focused on high‐leverage areas of thermonuclear ignition to which LANL can apply its historic strengths and that are complementary to high‐energy‐density‐physics topics. Using the Trident and Omega laser facilities, experiments are pursued in laser‐plasma instabilities, symmetry, Be technologies, neutron and fusion‐product diagnostics, and defect hydrodynamics.

Abstract

A peak fusion power production of 9.3±0.7 MW has been achieved on the Tokamak Fusion Test Reactor (TFTR) in deuterium plasmas heated by co and counter injected deuterium and tritium neutral beams with a total power of 33.7 MW. The ratio of fusion power output to heating power input is 0.27. At the time of the highest neutron flux the plasma conditions are: Te(0)=11.5 keV, Ti(0)=44 keV, ne(0)=8.5×1019 m−3, and 〈Zeff〉=2.2 giving τE=0.24 s. These conditions are similar to those found in the highest confinement deuterium plasmas. The measured D‐T neutron yield is within 7% of computer code estimates based on profile measurements and within experimental uncertainties. These plasmas have an inferred central fusion alpha fraction of 0.2% and central fusion power density of 2 MW/m3 similar to that expected in a fusion reactor. Even though the alpha velocity exceeds the Alfven velocity throughout the time of high neutron output in most high power plasmas, MHD activity is not substantially different from that in co...
