James Tuck, Perhapsatron, 1953

Los Alamos has a long history of fusion research

Today magnetic and inertial fusion work resides in the Physics Division, Theory Division, and X Division (Weapons). There are also related capabilities in detectors, radiation damage, and tritium handling.
Dr. John Kline ( [email protected] ) is the present Fusion Energy Sciences

(and Inertial Fusion) program manager, and a point-of-contact.

FRC’s were developed in Russia and Los Alamos

FRC’s are high beta plasmas, with many interesting features

Managed by Triad National Security, LLC for the U.S. Department of Energy’s NNSA

Today FRC plasmas are still being explored

Magnetized Plasma Team in P-24 Plasma Physics

We do experimental plasma work for FES, APRA-E, and NNSA sponsors, with national partners, and including small businesses. We use our knowledge of plasma diagnostics, pulsed power expertise, and HED plasmas in the areas of fusion energy, weapons support, and basic plasma science.

The Plasma Liner Experiment at LANL

This was an ARPA-E “ALPHA” project. Presently PLX has18 plasma guns in a hemispherical geometry, on a 2.75 m diameter chamber. It is being used to study the merging hypersonic plasma jets. Later in 2020, it may be upgraded to a full set of 36 guns. PI: Sam Langendorf, [email protected]

LANL Advanced Diagnostics

What: A new type of diagnostic using laser inverse Compton scattering to measure soft x-rays generated from laser photons scattering off of runaway (relativistic) electrons in the DIII-D tokamak

Where we are: ($480k FY18) Multi-institution design study for Laser Inverse Compton Scattering (LICS) Diagnostic for Runaway Electron measurements on the DIII-D tokamak is in progress. Completion of reviews by early FY20. Present investment is $820k for design study (LANL/GA/UCSD/Woodruff), and $1.15M for SBIR Phase I and Phase II (Voss Scientific). Where we are going: In FY21, The LICS runaway electron diagnostic design for DIII-D will be ready to move to a construction and installation phase, contingent on DIII-D schedule, port negotiations, and funding.
