Abstract

In this paper, we investigated the behavior of a type II superconducting armature when accelerated by a pulsed magnetic field generated by a single-stage pancake coil. While conducting this investigation, we performed a numerical finite element simulation and an experimental study of the magnetic field dynamics at the edge of the pancake coil when the payload was a superconducting disc made from YBaCuO, cooled down to 77 K. The magnetic field measurements were performed using a CMR-B-scalar sensor, which was able to measure the absolute magnitude of the magnetic field and was specifically manufactured in order to increase the sensor's sensitivity up to 500 mT. It was obtained that type II superconducting armatures can outperform normal metals when the launch conditions are tailored to their electromagnetic properties.

摘要

在本文中，我们研究了由单级扁平线圈产生的脉冲磁场加速时II型超导电枢的行为。在进行这项研究时，我们对扁平线圈边缘的磁场动力学进行了数值有限元模拟和实验研究，其中有效载荷是由YBaCuO制成并冷却至77K的超导圆盘。磁场测量使用CMR-B标量传感器进行，该传感器能够测量磁场的绝对大小，并且是专门制造的，以便将传感器的灵敏度提高到500mT。结果表明，当发射条件根据其电磁特性进行调整时，II型超导电枢的性能可优于普通金属。
