Initial Results from the Phantom Fast Camera on HBT-EP

A Phantom v7.3 fast camera has been installed on HBT-EP. A 656nm filter is used to ensure the light measured is due to $\mathrm{D_\alpha}$ emissions and not from other sources. Since these $\mathrm{D_\alpha}$ emissions are proportional to the neutral density and the plasma density, structural information about the plasma response and its instabilities can be reconstructed using the perturbations from the time-averaged emission profile. In this poster, the experimental setup will be described and comparisons between data from the magnetics diagnostics and the emission fluctuations will be explored.
