Notes:
The method of cyclotron wave transmission for measuring the electron parallel momentum distribution is studied in a lower-hybrid driven tokamak plasma. Questions of resolution, sensitivity, and technique are addressed. Measurements are made of the suprathermal distribution produced by current drive as well as the incremental changes in the distribution function produced by short pulses of lower-hybrid waves. The results indicate that cyclotron wave transmission is well suited for studies of electron velocity space phenomena and may be used to detect the effect of diagnostic perturbations. This research was supported by the U. S. Department of Energy.
