准球形z夹紧可以直接在三维空间压缩泡沫或氘和氚，而圆柱形z夹紧只能在二维空间压缩内部负载。由于在三维空间中的压缩，准球面z夹紧比圆柱形夹紧更有效地对内部流体做pdV功。本文将介绍28MA 100ns ZR驱动器的准球面z夹紧载荷设计、准球面内爆零维（0D）电路模型的结果以及准球面内爆加热内部流体的一维流体动力学模拟结果。准球形z箍缩内爆的应用包括用于辐射驱动实验的高辐射温度源，用于处理放射性废物的中子源，以及用于发电机的聚变能源。
A quasi-spherical z-pinch may directly compress foam or deuterium and tritium in three dimensions as opposed to a cylindrical z-pinch, which compresses an internal load in two dimensions only. Because of compression in three dimensions the quasi-spherical z-pinch is more efficient at doing pdV work on an internal fluid than a cylindrical pinch. Designs of quasi-spherical z-pinch loads for the 28MA 100ns driver ZR, results from zero-dimensional (0D) circuit models of quasi-spherical implosions, and results from 1D hydrodynamic simulations of quasi-spherical implosions heating internal fluids will be presented. Applications of the quasi-spherical z-pinch implosions include a high radiation temperature source for radiation driven experiments, a source of neutrons for treating radioactive waste, and a source of fusion energy for a power generator.
