We have calculated the behavior of composite-shell DT-filled targets irradiated by constant-power (''unshaped'') 1-MeV electron beam pulses. The outer part of the shell (the ''ablator'') is composed of a lower-Z metal than the high-density inner part (the ''pusher''). The lower-Z ablator decreases the bremsstrahlung heating of the pusher. The resulting colder and denser pusher is more effective. Breakeven requires about 360 TW deposited for 8 ns in a target about 3 mm in diameter. This is less than half the power required for targets composed of a single high-density metal shell filled with DT.
