摘要

我们详细分析了我们的新实验方法在约瑟夫森隧道结中电离粒子引起的热点的尺寸估计。这种方法是基于电离粒子对不对准的阿布里科索夫涡流的影响,这些涡流通过场冷却过程被捕获在结中。辐射的影响是旋涡的失调参数的变化。这反过来又引起约瑟夫森临界电流的变化,这可以用于热点大小的估计。

A hotspot size estimate technique by using Abrikosov vortices in Josephson tunnel junctions

We provide a detailed analysis of our new experimental method for the size estimate of the hotspot induced by ionizing particles in a Josephson tunnel junction. This method is based on the effect of ionizing particles on misaligned Abrikosov vortices, which are trapped in the junction by a field-cooling process. The effect of the radiation is the change of the misalignment parameter of a vortex. This, in turn, induces a change of the Josephson critical current, which can be used for an hotspot size estimate.
