Internal measurements on the Magnetized Target Fusion plasmas and overview of Pulsed Polarimetry techniques

Progress toward producing internal measurements of n$_{e}$, B and T$_{e}$ using Pulsed Polarimetry on the FRX-L device at LANL is detailed. The present laser, detection scheme and optical layout are described. The FRX-L field reversed configuration (FRC) plasma serves to develop the formation and translation hardware and scenario for Magnetized Target Fusion (MTF) program with n$_{e}$ and B approaching 10$^{23}$ m$^{-3}$ and 5 T and T$_{e}\sim $100 eV. An overview of Pulsed Polarimetry measurement scenarios across the High Energy Density (HED) regimes represented by the MTF program and other HED plasmas is presented.
