Advanced Concepts for Photon Sources. Volume 2. Fast Switching of Vacuum Magnetic Energy Stores.
Abstract
Inductive (magnetic) energy sotrage systems are analyzed in terms of their application to generation of ultra-high power pulses. Such systems can transform low-power energy inputs into high-power outputs (power multiplication) by shortening the energy delivery time. Energy transfer from magnetic store to resistive load can approach 100 percent efficiency. Models of several accelerated metallic plasma transfer switch geometries indicate that such switches can be energetically efficient and can produce substantial voltage multiplications. Using a versatile and extensively diagnosed apparatus, experiments were conducted to test these predictions. The experiments confirmed the modeling and established design criteria for metallic wire plasma switches. Operating at 25 kJ energy level, a coaxial switch produced narrow (60 to 300 nsec) voltage spikes with voltage and power multiplications of 3.
