摘要

介绍了圆柱形铝负载箔和梯度厚度铝真空开启开关箔的制备方法。负载箔在焦耳加热下蒸发,在J/ sp1倍/B力下内爆,在轴上停滞并产生软x射线。等离子流开关箔安装分流的真空功率流通道的同轴枪,并通过焦耳加热汽化。所得的梯度密度等离子体被磁驱动沿环形功率流通道向下移动。当分流等离子体穿过中心导体中的负载槽时,就会发生开闸动作。这些箔组件已经在Pegasus和Procyon实验中使用。

Physical vapor deposited aluminum foils for high energy density physics experiments
Fabrication of cylindrical aluminum load foils and graded thickness aluminum vacuum opening switch foils is described. Load foils are vaporized by Joule heating and imploded by J/spl times/B forces to stagnate on axis and create soft X-rays. Plasma flow switch foils are mounted to shunt the vacuum power flow channel of a coaxial gun and are vaporized by Joule heating. The resultant graded density plasma is magnetically driven down the annular power flow channel. Opening switch action occurs when the shunt plasma crosses a load slot in the center conductor. These foil components have been used in both the Pegasus and Procyon experiments.
