FIG. 1.

(a) Schematic diagram showing the incoming main pulse being reflected by a target foil. A plasma half cavity is used to back reflect and refocus the laser energy onto the target. (b) The intensity ratio of the pulses is determined by the combined reflected energy fraction, F, of the accelerating foil front surface and cavity foil interior, the delay between the pulses, , is set as 2r/c where r is the radius of the half cavity.

(a) The proton spectra for a planar foil and three of the half cavity target geometry tested, inset: linear scale. (b) The enhancement factor (defined in text) as a function of energy for each of the plasma half cavity proton spectra.

FIG. 3.

The integrated experimental doses compared with simulation results. Both experimental and simulation results are normalized to the corresponding single pulse planar foil interactions.
