计算和实验研究结果的核诱导电导率增强在3 He讨论与应用磁流体动力学（MHD）能量转换。计算的基础上的标准模型的相互作用和导电性的气体中的部分电离的3 He建议一个区域的条件，以前没有考虑可能提供显着的导电性增强。具体地，在密度小于标准大气密度和中子通量大于1×1012/cm 2/s的情况下，可以实现大于10 mho/m的电导率。这些计算还表明，对于可实现的条件范围，几百mho/m的电导率是可能的。此外，计算表明，核诱导电导率是强的密度依赖和弱的温度依赖。因此，与利用热电离的传统MHD通道中典型的那些相比，更高的流速以及因此更高的功率密度将是可能的。实验是……
The results of a computational and experimental investigation of nuclear-induced electrical conductivity enhancement in 3He is discussed with application to magnetohydrodynamic (MHD) energy conversion. Calculations based on the standard model of interactions and conductivity in a gas of partially ionized 3He suggest a region of conditions not previously considered may provide significant conductivity enhancement. Specifically, at densities less than standard atmospheric density and neutron flux greater than 1×1012/cm2 s, conductivity greater than 10 mho/m may be achievable. These calculations also suggest conductivities of several hundred mho/m may be possible for an achievable range of conditions. Additionally, the calculations show that nuclear-induced conductivity is strongly density dependent and weakly temperature dependent. Therefore, higher flow velocities, and hence higher power densities than those typical in traditional MHD channels utilizing thermal ionization would be possible. Experiments wer...
