The time evolution of electron temperature (Te) profile and electron velocity distribution can be obtained by means of the new soft X-ray pulse height analysis(PHA) array system. Preliminary experimental results obtained from the PHA system show that the Te profile during ohmic heating (OH) phase is correspondingly flat,and close to the analogical parabola form of 1.0×[1-(r/a)2]2; the Te profile become peaking during near-axis ECRH (0.8 MW),the Te in the plasma center (z=0) increase 0.6 keV,however,the increment of Te in the plasma edge (z=30cm) is only 0.1keV,a mass of high-energy electrons are generated during ECRH phase,therefore,the electron velocity distribution is changed evidently during ECRH; both the number and energy of the high-energy electrons is larger in plasma center (z=0) than that in plasma edge (z=30cm),the energy of high-energy electrons in plasma center can extend to 17keV. It can be concluded from the experimental results that heating effect of ECRH is very obvious,the energy of ECW is mainly deposited in the plasma center during near-axis ECRH (Bt=1.3T) discharges,and the electron velocity distribution changes from Maxwellian to non-Maxwellian normally.
