Paper Abstract

A 2-D multichannel interferometer designed for tomographically inferring contours of electron density in the WT-3 tokamak plasmas (R≃0.65 m, a≃0.2 m, Bτ≤1.75 T) with high time resolution is described. A frequency shift of wlF=1.45 MHz for a local beam splitted from a 337 μm HCN laser beam is obtained by use of a super rotating grating /1/, which allows the time resolution of the density measurements as fast as τ≃10 μsec.
