    Abstract

    Imaging Motional Stark Effect (IMSE) is a new type of MSE polarimeter[1], used to measure 2D images of the polarisation angle of neutral beam Ha emission, for diagnosis of the plasma current profile. An IMSE diagnostic was installed on ASDEX Upgrade (AUG) to quantify the accuracy and capability of the measurement. Prior to installation, the system was subjected to a series of tests under known lab conditions to assess the ideal accuracy, choose certain operating parameters and to demonstrate several features of the method. These results are reported here, including some unanticipated effects that were discovered and mitigated. The results of the subsequent successful operation at AUG are reported at the EPS 2013 conference (O2.110).
