Abstract

This report demonstrates how the electron line density and the poloidal magnetic field can be measured simultaneously, using only a polarimeter. In this way the full state of polarisation of radiation transmitted across the plasma is determined. The proposed device is simpler and more flexible than the more conventional interferometers/polarimeters currently used in tokamaks.
