The PTO linear induction accelerator

OSTI ID:6332295
The PTO accelerator is a test-bed for the study of issues involved in the development of compact, repetitive, high-duty cycle, linear induction accelerators (LIA). The need for multi-microsecond pulse lengths is incompatible with compact ferrite size. Therefore, a long burst of short pulses with a 100% voltage reversal and a 50% duty cycle was chosen as the operating mode of PTO. The 100% voltage pulse reversals between accelerating pulses reset the magnetic cores, allowing a compact ferrite size. PTO will consist of an 800-kV injector to generate an electron beam (approx.1 kA) and two 200-kV induction cavities to accelerate the beam. Two different operational modes will be implemented. The first (Drive Mode 1) is a short burst (three pulses) of high frequency (20-MHz) bipolar square waves to study diode beam dynamics and to characterize accelerating cavity behavior. Drive Mode 2 will be a multi-microsecond ringing waveform (with greater impulse spacing) that will alternately saturate the cores in each polarity. The driving mechanism will facilitate the study of plasma closure rates in the diode and accelerating gaps. The pulsed power and cavity designs will be presented.
