Abstract

Continued development in inertial fusion reactor research identifies the potential of providing beam of heavy ions associated with long pulse duration, low level of Kinetic energy and multi-killoamperes current. This paper presents continuation of work for the ultimate goal of precision design in the spark gap switching mechanism for the linear induction accelerators including the core type as well as the line type. The pulse switching involves the utilization of the saturable – resistor with hard ferromagnetic material core, where sudden changes in its ohmic value can provide precise automatic switching synchronized with that of the charging beam. Calculations centered on establishing remarkable switching sequence spectrum with respect to the fundamental frequency as well as for a discrete sequence of harmonics contained in the saturable resistor exciting current. Discrete time switchings are characterized in the form of discrete pulses with continuous ascending sharp increase in amplitude and controlled reduction in time duration.
