IBEX - a pulsed power accelerator that generates no prepulse
Intense relativistic electron beams are produced in vacuum diodes driven by pulsed power accelerators. For pulse widths approx. 100 nsec, pulse forming lines (PPL) are used to generate the accelerating voltage pulse. This pulse is produced by sequential switching of stored energy through two or more stages. Capacitance and/or inductive coupling usually results in the generation of a low level prepulse voltage some time during the switching sequence. This prepulse is known to have a substantial effect on the performance of the vacuum diode during the main accelerating pulse. Most accelerators use various schemes for reducing this prepulse to acceptable levels. The Isolated Blumlein PPL concept was developed at Sandia to allow for the generation of the main accelerating pulse without generating a prepulse voltage. This concept was implemented into the IBEX accelerator that generates a 4 MV, 100 kA, 20 nsec output pulse. Design and performance data are presented.
