Optimization of Linear Induction Radiography Accelerator with Electron Beam with Energy Variation

The current interest for the next generation linear induction radiography accelerator (LIA) is to generate multiple electron beam pulses with high peak currents. The beam energy and current may vary from pulse to pulse. Conse-quently, the transport and control of multi-pulsing intense electron beams through a focus-ing lattice over a long distance on such machine becomes challenging. Simulation studies of multi-pulse LIAs using AMBER [1] and BREAKUP Code [2] are described. These include optimized focusing magnetic tune for beams with energy and current variations, and steering correction for corkscrew motion. The impact of energy variation and accelerating voltage error on radiograph performance are discussed.
