Multi-Point Thomson Scattering Diagnostic

The obtainment and implementation of Thomson Scattering (TS) equipment from Lawrence Livermore National Laboratory will allow for the upgrade of the TS system at HBT-EP from a single spatial-point to a multiple spatial-point system. The additional spatial-points allows for a more developed profile of electron temperature and density via an equilibrium reconstruction process. This allows for multi-mode feedback control and stability calculations over a larger spatial region. Subsequently the multipoint reconstruction should enable the separation of \textit{$\beta $}$_{p}$, the ratio between plasma pressure and poloidal magnetic field pressure, and $l_{i}$, the plasma's internal induction, which cannot otherwise be separated on HBT-EP. Over the summer, work on the installation and alignment of the TS system was performed during a 5-week internship. Progress made over that time window will be reported.
