“凹凸不平的Z箍缩”是一种对聚变反应堆有潜在用途的磁结构。概念上简单的构型是轴对称的。它包含封闭和开放场线的区域。在闭合场线的区域中，场线拓扑结构很像托卡马克的场线拓扑结构;这些区域围绕对称轴将开放场线的区域连接起来。假设等离子体自发地保持如J. B.泰勒，这是可能的，以保持无限的区域封闭的场线驱动轴向电流通过等离子体的区域中的开放的场线。在每个托卡马克类区域中的总轴向驱动电流与总极向电流之间的比率原则上可以任意小，这意味着负载阻抗可以任意大。此外，该结构还具有与球马克结构类似的固有优点，即等离子体的类托卡马克部分不连接任何物质线圈。
The ‘bumpy Z-pinch’ is a magnetic configuration with potential usefulness for fusion reactors. A conceptually simple version of the configuration is axisymmetric. It contains regions of closed and open field lines. In the region of closed field lines, the field line topology is much like that of a tokamak; these regions link the region of open field lines around the axis of symmetry. Assuming that the plasma spontaneously maintains an equilibrium as described by J. B. Taylor, it is possible to maintain indefinitely the regions of closed field lines by driving an axial current through the plasma in the region of open field lines. The ratio between the total axial driven current and the total poloidal current in each of the tokamak-like regions can, in principle, be made arbitrarily small, which means that the load impedance can be arbitrarily large. In addition, the configuration has the inherent virtue similar to that of the spheromak that the tokamaklike part of the plasma does not link any material coils.
