Multiple stage pulsed induction acceleration

The acceleration mechanism utilized by a Pulsed Induction Accelerator (PIA) is based on the repulsive force generated in conformance with Lenz's law between the drive coil and the coil of the projectile. In the single stage PIA, there is only one coil pair. In the multiple stage accelerator a single projectile coil provides one accelerating stage in connection with each successive drive coil. Advantages of PIAs over other electromagnetic launchers include multiple staging, absence of physical contact, high operating efficiency, simplified force containment, and high electrical impedance. Limitations of PIAs are related to the need for synchronization, the requirements for fast control and switching systems, and the production of large induced voltages. Attention is given to aspects of theory and analysis, the major goals of experimental work, and the results of development work.
