[en] Recent progress in the Sandia REB Fusion Program is reviewed including theoretical and experimental results on focusing, deposition, and pellet implosion. Measurements of time-dependent pinching of the beam are compared with numerical models including diode plasmas. The self-field of a beam has been included in a beam-deposition model and experiments involving front- and rear-surface diagnostics are presented. Spherical and hemispherical gold shells have been imploded using one and two beams and bremsstrahlung output as well as separate flash radiographs are given. Short-pulse accelerator technology requirements and developments are discussed and an example of a typical pellet design calculation is shown. (author)
