介绍了2 × 200 kJ-1 MW脉冲功率高温超导磁储能演示装置的设计。其目的是在小规模测试电磁发射器供电的各种可能性。预见的操作模式包括电力电容器中的高压放电、来自两个耦合线圈的相同能量的顺序放电以及XRAM电流倍增。特别注意线圈的布置，以使释放的能量相等。线圈由三个低温冷却器的传导冷却;热设计进行了优化，以保持线圈在15 K左右，尽管XRAM操作所需的大量电流引线（8个）。初步测试的演示，示出的热和电气特性是在非常好的协议与设计目标。
The design of a twin coil 2 x 200 kJ-1 MW pulse power high temperature superconductor (HTS) superconducting magnetic energy storage (SMES) demonstrator is presented. Its aim is to test at small scale various possibilities of electromagnetic launcher powering. The foreseen operation modes include high voltage discharge in power capacitors, sequential discharges of identical energies from two coupled coils, and XRAM current multiplication. Special attention was paid to the arrangement of the coils for the energies discharged to be equal. The coils are cooled by conduction from three cryocoolers; the thermal design was optimized in order to maintain the coils around 15 K in spite of the high number of current leads required for XRAM operation (eight). Preliminary tests of the demonstrator are also presented, showing that the thermal and electrical characteristics are in very good agreement with the design objectives.
