Detailed spectroscopic diagnostics of the stagnating plasma in two disparate z pinches allow, for the first time, the examination of the plasma properties within a 1D shock wave picture, demonstrating a good agreement with this picture. The conclusion is that for a wide range of imploding-plasma masses and current amplitudes, in experiments optimizing non-Planckian hard radiation yields, contrary to previous descriptions the stagnating plasma pressure is balanced by the implosion pressure, and the radiation energy is provided by the imploding-plasma kinetic energy, rather than by the magnetic-field pressure and magnetic-field-energy dissipation, respectively.
详细的光谱诊断停滞的等离子体在两个不同的 Z 夹，第一次允许，检查的等离子体特性内 1D 冲击波图片，证明了这一图片的良好协议。结论是，对于广泛的内爆等离子体质量和电流幅度，在实验优化非普朗克硬辐射产量，与以前的描述相反，停滞的等离子体压力由内爆压力平衡，辐射能量由内爆等离子体动能提供，而不是由磁场压力和磁场能量耗散分别提供。
