Fig. 1

a Hemisphere + cone (HC) targets were alternately driven by either the backlighter (BL) beam (~6 ps) or the sidelighter (SL) beam (~12 ps), with a 10-μm thick solid Cu slab positioned at the cone tip. b A flat target was driven by the SL beam, with a 200 μm thick Cu slab placed 430 μm away [same source-to-target standoff distance as in (a)]. The Kα emission was measured by the HiResSpec instrument37, with the line-of-sight indicated in the figure. The source and transmitted proton beams were characterized by a Thomson parabola (TPIE) and radiochromic films (RCF), where the source was obtained using HC targets without a Cu slab. Note that (a, b) are not on the same scale.
