Diagnostics and Characterization

From high-speed imaging to plasma diagnostics to characterizing micrometer-scale features of sub-millimeter-scale components, General Atomics has decades of experience in delivering world-leading analytical services for some of the most important scientific research taking place in the energy sector. Innovations that GA researchers have delivered to government and private clients continue to provide value across a wide range of scientific fields.

For ITER
In addition to supplying the ITER Central Solenoid, GA is providing an array of fusion plasma diagnostics. These include a Low-Field-Side Reflectometer that will use microwaves to measure plasma density profiles, a Wide Angle Visible and Infrared Viewing System to monitor for hot spots in the ITER plasma chamber, and a Toroidal Interferometer Polarimeter to measure plasma density distribution.

For DIII-D
GA's decades of experience in plasma diagnostics has been a key factor in the success of the DIII-D Research Program, which GA operates for the Department of Energy. A critical element in the support of DIII-D is the development of new measurement capabilities. Much of the successful diagnostic development and diagnostic implementation on DIII-D in the past several years has been done in collaborations between GA and other institutions.

For High-Energy-Density (HED) Physics
HED experiments require precise, ultra-high-speed instruments to record implosion events and related data. GA has pioneered cutting-edge imaging systems for the NIF and other clients.
