抄録

For Deuterium-Helium-3 (D3He) fueled field-reversed configuration (FRC) plasmas, the influence of the magnetic configuration on distortion in the triton velocity distribution function when ion cyclotron range of frequencies (ICRF) wave is injected is investigated. Some of the tritons in the FRC are asymmetrically lost from the device, and the loss further enhances the distortion in the distribution function. Using the distorted distribution, the reduction in the 14-MeV neutron generation rate by ICRF wave injection is estimated considering the influence of the magnetic configuration. It is found that in a typical ignited D3He/FRC plasma, (Ti = T e = 80 keV, nD = 2n3He = 0.5ne = 2.0×1020 m-3, τE = 0.5τp = 3.0 sec, rs = 1.6 m, ls = 20 m, Bw = 6T, QRF = 100), the reduction in the 14-MeV neutron generation rate is about 40%.
