Experimental setup. (a) Schematic of the experimental setup showing the three main proton monitoring systems: a TP spectrometer at \(0^\circ\), a TOF line at \(180^\circ\) and a Spectralon diffuser. (inset) Target holder specifically designed for holding the NW discs. (b–e) SEM images showing (b), a top view of the nanowire target. (c–e) different NW targets of different lengths (0.3 \(\upmu\)m in (c), 1.5 \(\upmu\)m in (d) and 8 \(\upmu\)m in (e).
