A developing application of laser-driven currents is the generation of magnetic fields of picosecond–nanosecond duration with magnitudes exceeding $B=10~\text{T}$ . Single-loop and helical coil targets can direct laser-driven discharge currents along wires to generate spatially uniform, quasi-static magnetic fields on the millimetre scale. Here, we present proton deflectometry across two axes of a single-loop coil ranging from 1 to 2 mm in diameter. Comparison with proton tracking simulations shows that measured magnetic fields are the result of kiloampere currents in the coil and electric charges distributed around the coil target. Using this dual-axis platform for proton deflectometry, robust measurements can be made of the evolution of magnetic fields in a capacitor coil target.

电容器线圈目标沿两个轴的质子偏转测量

激光驱动电流的发展应用是产生皮秒至纳秒持续时间的磁场,其幅度超过 $B=10~\文本{T}$ . 单环和螺旋线圈​​目标可以引导激光驱动的放电电流沿导线产生空间均匀的毫米级准静态磁场。在这里,我们提出了跨直径从 1 到 2 毫米的单环线圈的两个轴的质子偏转测量。与质子跟踪模拟的比较表明,测量的磁场是线圈中的千安电流和线圈目标周围分布的电荷的结果。使用这种用于质子偏转测量的双轴平台,可以对电容器线圈目标中的磁场演变进行稳健的测量。
