Abstract
A polarimeter for the circular polarization of Zeeman-split spectral line emissions has been developed to measure the poloidal magnetic field in tokamak plasmas. The Li I 6708 Å line originating from a monoenergetic lithium beam provided a localized spectral source. In the polarimeter, interference filters of narrow bandpass were set at the peak wavelength of the circular polarization, enabling the measurement to be continuous and sensitive.
