To measure the behavior of high energy ions, a semiconductor detector (named: ccHED) is installed at the central cell mid-plane of GAMMA 10. When ccHED is located at the radius of R=25cm from the center of plasma, the burst like signal is observed. To investigate this burst like signal, FFT method is applied to the signal of ccHED and signal of electrostatic probes (ESPs) which is used to measure fluctuations. As a result, it is clearly observed that the frequency component of the burst like signal has the same peak as one of the frequency components of the fluctuations. The amplitude of the signal has the pitch angle dependence. These observations suggest the existence of the radial transport of high energy ions due to the drift-type fluctuations.
