AbstractAbstract
[en] An analytical expression of the integral transport method for an experimental hole in fission reactors has been developed. This analytical method might still be useful for designing a fusion reactor without using large computer machine time

AbstractAbstract
[en] The results of the recent, high power ICRH experiments performed on the ST Tokamak are reported. It was demonstrated that both the fast and slow waves could be generated in toroidal geometry, and heating of the plasma ions at power levels up to 1 MW was observed both at the ion cyclotron frequency (ω/sub ci/) and its second harmonic (2ω/sub ci/). Measurements by a charge exchange neutral detector directed tangentially to the plasma torus revealed that at 2ω/sub ci/ the ion energy within the bulk of the ion distribution function (''parallel body temperature'') could be increased from about 100 eV up to 200 eV with efficiencies ranging from 8 to 45 percent. Efficiency at ω/sub ci/ in raising the parallel temperature was less than at 2ω/sub ci/. Charge exchange neutral detection perpendicular to the plasma column showed that both at ω/sub ci/ and 2ω/sub ci/ the ''perpendicular body temperature'' was enhanced very rapidly by a factor of up to 3. Also, buildup of a high energy ''tail'' in the ion energy distribution was observed. Power transfer to the ions seemed extremely efficient. (auth)

AbstractAbstract
[en] The enhancement of resonance molecular formation rates of [dtμ,d2e] and [ddμ,d2e] by strong laser irradiation have been studied. The formation rates decrease until the laser intensity reaches the order of 108 to 109 W/cm2, and they increase substantially for the intensity range of 1010 W/cm2 to 1011 W/cm2. The [dtμ,d2e] formation rate using the angular frequency laser such as 11.4 x 1013 rad/sec becomes 4 x 1010 l/sec for the laser intensity of 3 x 1010 W/cm2. Further increase of laser intensity reduces the formation rate due to the mismatch of the resonance condition. The formation rate is very sensitive to the frequency of the laser and the formation rate of [ddμ,d2e] becomes comparable with one of [dtμ,d2e] for the cases of w = 22.8 x 1013 rad/sec. For the case of dt initial molecule, there is the possibility of enhancing the formation rate by exciting the vibrational motion by laser field
