1. INTRODUCTION
The main problems to be solved in the recent experiment on T-10 in 1988 were:
(a) The dependence of the energy confinement on the power deposited in the
plasma;
(b) The dependence of the energy confinement on the plasma current.
A set of 11 gyrotrons, the same as was used in the work described in [1], with
a total power of PRF « 3.5 MW, was used on T-10. The absorbed power was
determined from the derivatives of a diamagnetic signal; the power profile, Pab (r),
was found from the derivatives of the radiation intensities at the second ECR harmonic.
The wavelengths of the gyrotrons were \{ = 3.7 mm and X2 = 4 mm, the
same as in [1].
2. DEPENDENCE OF ENERGY CONFINEMENT ON
PLASMA PARAMETERS
The results of research work on the time dependence of energy confinement on
the plasma line averaged density, r^, and on the plasma current, Ip, with ECRH on
T-10 were given in [1].
The dependence W(n
