Abstract :
Diagnostics in infrared and far-infrared range for Heliotron E are described; (a) FIR interferometer for measuring electron density profile and (b) ECE for electron temperature profile as routine work, and (c) Fraunhofer diffraction method with a CO/sub 2/ laser for density fluctuation and (d) Thomson scattering with a D/sub z/O laser (/spl lambda/ = 385 /spl mu/m) for Ion temperature, as new methods.
