Many tokamaks now use visible light cameras to observe plasma-wall interactions and integrated line emission. The DIII-D Coherence Imaging Spectroscopy diagnostic cameras image interferograms that encode line integrated flow. By modeling the 2D camera image pixels as line-of-sight integrals through an axisymmetric discrete grid it is possible to do tomographic analysis to determine the local...
The analysis approach often called “integrated data analysis” (IDA) provides a means to exploit all information present in multiple streams of raw data to produce the best estimate of a plasma parameter. This contrasts with the typical approach in which information (data) from a single diagnostic is used to measure a given parameter, e.g., visible bremsstrahlung→Zeff or Thomson scattering...
The Magnetized Liner Inertial Fusion (MagLIF) concept has recently demonstrated Gbar pressures, confinement of charged fusion products, and substantial fusion yield. We have developed a new analysis methodology that allows for the self-consistent integration of multiple diagnostics including nuclear, x-ray imaging, and x-ray power measurements to determine important stagnation parameters. The...
To achieve a symmetric implosion with indirect drive, it is crucial to understand the dynamic behavior of laser transport in the hohlraum. This is particularly important in targets with lower initial gas-fill density since the region of the hohlraum wall irradiated by the outer cone beams bulges into the gas and can impair the propagation of the inner cone beams. Similarly, material ablated...
