Schematic of orifice employed in the neutron-imaging campaign revealing the internal flow path. The external shape has been modified to allow the scintillator crystal to approach the flow region of interest as much as possible, subsequently enhancing the spatial resolution of the imaging technique. The same nominal flow path has been employed in past campaigns exploring the suitability of synchrotron irradiation for cavitation visualisation and quantification33. The wall thickness for the particular test piece is equal to 4 mm. Nevertheless, the orifice manufacturing technique (electrical discharge machining) caused the orifice offset to deviate from the location set in the drawings. Geometry files for the orifice, needle and their assembly (both for 0.5 mm and 1.0 mm lift values) are provided as Supplementary Material to allow the reproduction of the actual test-piece employed in experiments. Dimensions are in mm.
