Abstract

The second axis of the Dual Axis Radiography of Hydrodynamic Testing (DARHT) facility produces up to four radiographs within an interval of 1.6 microseconds. It accomplishes this by slicing four micro-pulses out of a long 1.8-kA, 16.5-MeV electron beam pulse and focusing them onto a bremsstrahlung converter target. The long beam pulse is created by a dispenser cathode diode and is accelerated by the unique DARHT Axis-II linear induction accelerator (LIA). Beam motion in the accelerator would be a problem for radiography. High-frequency motion, such as from the beam breakup instability, would blur individual spots. Low-frequency motion, such as produced by a pulsed power variation, would produce spot-to-spot differences. In this article, we describe these sources of beam motion and the measures we have taken to minimize it.
