Overview of Present and Planned Diagnostics of the Plasma Liner Experiment (PLX)

The Plasma Liner Experiment (PLX) is studying an innovative fusion approach, plasma-jet-driven magnetoinertial fusion (PJMIF). We provide an overview of the diagnostic approaches planned to assess critical characteristics of the implosion, and ultimately the device's potential as a controlled fusion apparatus. Liner uniformity, which can influence the ultimate target compression ratio and instability growth rate, may be examined using a set of high-speed cameras at various vantage points, making use of spectral techniques to enhance contrast and tomographic reconstruction of 3D spatial profiles. Relative emission strengths will used to determine electron temperature and impurity presence in the liner via UV-VIS-NIR imaging spectrographs. Bolometers will be implemented to gauge the radiated power from the liner, which is indicative of the liner stagnation parameters via comparisons with integrated modeling. Other diagnostics include a set of fish-eye CCD cameras which will be used to determine individual jet speeds and balance, the existing multi-chord interferometer system to determine line-integrated electron density, and lastly both traveling and fixed Thomson scattering systems in the design stage, which will be used for characterization of the eventual magnetized target.
