Become a DIII-D Participant

The DIII-D program is a national and international collaboration among over 90 institutions. Collaborators lead and manage elements of the program, generate ideas and innovations, lead experiments, build and operate diagnostics and equipment, analyze data, provide theory and modeling, and report and publish results. Join our effort.

The overall goal of the DIII-D program is to establish the scientific basis for the optimization of the tokamak approach to fusion energy. At the heart of the DIII-D program is the development of the basis for steady-state high performance Advanced Tokamak scenarios in support of burning plasmas and attractive fusion energy systems. The research program includes major elements of fusion science: transport, stability, energetic particles, pedestal and boundary physics. The hallmark of the DIII-D program is its emphasis on integration of these science issues and model validation.

The DIII-D program is committed to resolving critical issues to ensure the success of ITER, and to developing long pulse and steady-state scenarios that will enhance the scientific and technological benefit of ITER operation, and by developing model-based plasma control technology. The program is carrying out world leading experiments in stabilization of resistive wall modes and neoclassical tearing modes, pioneering work in control of edge instabilities, first wall erosion and migration experiments that address tritium retention in ITER, and experiments to validate safe rapid plasma shutdown in case of loss of control. DIII-D actively participates in the International Tokamak Physics Activity (ITPA) and internationally coordinated multi-machine experiments to investigate fusion science issues and integrated advanced scenario optimization, and to address ITER research needs.

New facility capabilities implemented in the last two years position the DIII-D program for an exciting experimental campaign. New capabilities include increased EC power and pulse duration, co plus counter neutral beam injection, density control for high triangularity double-null divertor plasmas, and many improved diagnostic measurements.
