Proton beam profiles from scintillator measurements for shots 1, 3 and 5. Two different absorber configurations (sketch) with spatially varying threshold energies (40, 80 and 100 MeV, respectively) were used. There is a clear shift of the acceleration direction of the high-energy protons towards the laser direction (smaller angles). The spectrometers’ axes are indicated by coloured circles (TPS15, blue; TOF31, green; TPS45, orange), and grey areas indicate parts without data. Horiz., horizontal; Norm, normalized; Vert., vertical.
