AbstractAbstract
[en] A system is designed to measure the fluorescence light emitted from the transitions 1S-2P of L sub alpha line (lambda=1215 A) or 2P-2S or 2P-3D of H sub alpha line (lambda=6563 A), excited by the laser induced fluorescence method. The signal-to-noise ratio (S/N) is evaluated at the measurement in the parameter (n-bar sub e = 10 to the 12th to 10 to the 14th per cu. cm, T sub e = 10 eV - 1 KeV) of tokamak plasma. The light paths in JFT-2M and JT-60 tokamaks are proposed
