A novel macroparticle accelerator is proposed that employs cascaded electron beam diodes as drivers to ablatively accelerate projectiles to hypervelocities. Each unit stage of the accelerator consists of Marx generator, a pulse forming line, an electron beam diode, and a pellet guide tube. A solid projectile is accelerated by successively incident self-pinching electron beam pulses from a cascade of annular electron beam diodes set along the axis of a pellet trajectory. A launch efficiency of 100 % is possible in theory by controlling of velocity and mass of ablating material. A tentative concept of the accelerator is presented as one of the impact fusion drivers.
