摘要：

The existing single point Thomson scattering apparatus on JET has been modified to allow measurements of local magnetic fields. Multiviewing access will be provided by axicone optics, giving a scattering angle of about 4°, and should provide an accuracy of better than 10% in measuring Bpol over most of the plasma radius. A Fabry-Perot spectrometer will detect the scattered spectra, modulated at the electron gyrofrequency, using a gated image intensifier and a cooled CCD camera. The location of an interference partial fringe will give the magnetic field vector at a particular position in the plasma. From the locus of such partial fringes, the q profile may be determined.
