Poloidal polarimeter for current density measurements in ITER
One of the systems envisaged for measuring the current density profile in the ITER is a 118 mu m poloidal polarimeter system. The proposed system has two independent views: one fan of chords observes the plasma via an equatorial port and a second fan views down from an upper port. This article will present the status of the on-going work and will address issues as sensitivity and accuracy, refraction, Gaussian beam ray-tracing, alignment, and calibration as well as some specific design details.
