The particle flux is obtained from the integration of eq. (1) as follows:
Eq. (2) can be rewrite as .
From the plotting of /n and n/n, the diffusion coefficient is obtained
from the gradient of the plotting
of shot 45596(Bt =1.8T)
intensity of shot 45572 (Bt = 2 T)
of shot 45572 (Bt = 2.0 T)
intensity of shot 45596 (Bt = 1.8 T)
of shot 45596 (Bt = 1.8 T)
of shot 45572 (Bt = 2 T, the chords at
+20cm, +10cm, 0cm, -10cm, – 20cm)
of shot 45572 (Bt = 2 T)
of shot 45572 (2 T)
The electron density diffusion coefficient of IBW 45596 (1.8 T)
heated plasma at Bt = 2 T and 1.8 T
The electron density diffusion coefficient for Ohmic 45596 (1.8 T)
and IBW heating at Bt = 1.8 T
Conclusions 45596 (1.8 T)
by the IBW heating in the HT-7 tokamak. The electron density was peaked, the Soft X ray intensity went up gradually, and the Ha radiation intensity dropped suddenly during IBW heating.
