Pulsed Polarimeter instrument for the Magnetized Target Fusion program

Pulsed polarimetry, a Lidar-\textit{like} technique, promises to provide internal measurements of the distributions of $n_{e}$, $B_{\vert \vert }$ and $T_{e}$ for the MTF program, the FRX-L and FRCHX FRC experiments at at LANL and Air Force Research Lab, Albuquerque. The instrument in its final form is mostly finished and testing is in progress. The optical system: collection and collimating optics, polarimeter, spectrometer and condensing optics are built. The laser and streak camera have been commissioned. A versatile instrument has been designed which is capable of covering a 30 cm depth of field for FRX-L plasma, has selectable spectrometers for different $T_{e}$ ranges for the FRCHX plasma and can be stationed at discrete distances of 3, 4 and 5 $m$ from the plasma. The design and performance and plans to implement the diagnostic on the FRX-L device at Los Alamos will be presented.
