Wire X-pinches (WXPs) have been studied comprehensively as fast ($\sim 1$ ns pulse width), small ($\sim 1$ $\mu$m) x-ray sources, created by twisting two or more fine wires into an “X” to produce a localized region of extreme magnetic pressure at the cross-point. Recently, two alternatives to the traditional WXP have arisen: the hybrid X-pinch (HXP), composed of two conical electrodes bridged by a thin wire or capillary, and the laser-cut foil X-pinch (LCXP), cut from a thin foil using a laser. We present a comparison of copper wire, hybrid, and laser-cut foil X-pinches on a single experimental platform: UC San Diego’s $\sim 200$ kA, 150 ns rise time GenASIS driver. All configurations produced 1–2 ns pulse width, $\le 5$ $\mu$m soft x-ray (Cu L-shell, $\sim 1$ keV) sources (resolutions diagnostically limited) with comparable fluxes. WXP results varied with linear mass and wire count, but consistently showed separate pinch and electron-beam-driven sources. LCXPs produced the brightest ($\sim 1$ MW), smallest ($\le 5$ $\mu$m) Cu K-shell sources, and spectroscopic data showed both H-like Cu K${}_{\alpha }$ lines indicative of source temperatures $\ge 2$ keV, and cold K${}_{\alpha }$ ($\sim 8050$ eV) characteristic of electron beam generated sources, which were not separately resolved on other diagnostics (within 1–2 ns and $\le 200$ $\mu$m). HXPs produced minimal K-shell emission and reliably single, bright, and small L-shell sources after modifications to shape the early current pulse through them. Benefits and drawbacks for each configuration are discussed to provide potential X-pinch users with the information required to choose the configuration best suited to their needs.

在200 kA，150 ns电流驱动器上直接比较线，箔和混合X引脚

线X夹（WXP）已被全面研究过（$〜\mathrm{1个}$ ns脉冲宽度），小（$〜\mathrm{1个}$ $\mu$m）X射线源，它是通过将两条或多根细线扭曲成“ X”形而产生的，从而在交叉点处产生极强的磁化局部区域。最近，出现了传统WXP的两种替代产品：混合X夹（HXP），它由两个由细线或毛细管桥接的圆锥形电极组成；以及激光切割的箔X夹（LCXP），它从细的地方切下来。用激光箔。我们在一个实验平台上展示了​​铜线，混合金属和激光切割箔X夹的比较：加州大学圣地亚哥分校的$〜200$ kA，150 ns上升时间GenASIS驱动器。所有配置产生的脉冲宽度为1-2 ns，$\le 5$ $\mu$柔和的X射线（铜L型壳， $〜\mathrm{1个}$ keV）源（诊断上受限的分辨率）具有可比的通量。WXP的结果随线性质量和线数而变化，但始终显示出单独的收缩和电子束驱动源。LCXP产生的亮度最高（$〜\mathrm{1个}$ MW），最小（$\le 5$ $\mu$m）Cu K壳源，光谱数据表明，两者均呈H型Cu K${}_{\alpha }$ 指示源温度的线 $\ge 2$ keV和冷K${}_{\alpha }$ （$〜8050$ eV）电子束生成源的特性，在其他诊断程序（1-2 ns之内和 $\le 200$ $\mu$m）。经过修改以塑造通过它们的早期电流脉冲后，HXP产生的K壳发射极小，并可靠地产生了单个，明亮和小的L壳源。讨论了每种配置的优缺点，以为潜在的X捏用户提供选择最适合其需求的配置所需的信息。
