Description

Improvement of the signal to noise ratio of the measurement of electron cyclotron emission (ECE) by scanning Fabry-Perot interferometer is reported. The most important point is the use of the glass beads filter in addition to the capacitive mesh low pass filter. The result of frequency response calibration of the total system is described. The time evolution of the high energy electrons (-100keV) produced in RF current driven tokamak WT-III due to the estimate from the ECE measurement is reported.
