Abstract
Summary form only given. The Laboratory Microfusion Facility (LMF) has been proposed for the study of high-gain, high-yield inertial confinement fusion targets. Bunching factors of /spl alpha/ = 2-3 are being considered for LMF. The light-ion transport schemes which have been studied most extensively include ballistic transport with solenoidal lens focusing, z-discharge channel transport, and wireguided transport. Transport efficiency, /spl etasub t/, has been calculated previously for all three systems as a function of beam microdivergence, diode radius, and focal distance. In those studies a monoenergetic beam was assumed. Work is presently underway to evaluate the effect that voltage ramping for time-of-flight bunching has on /spl etasub t/ for each of the transport schemes. The bunching factor, number of modules, and total ion energy available to drive the target will be varied to establish their effect on /spl etasub t/.
