abstract = {{At Diamond Light Source two X-ray pinhole cameras are used to measure the transverse profile of the 3 GeV electron beam. The current pinhole assembly is formed using tungsten blades with chemically etched shims to produce a 25 µm x 25 µm aperture and the imager incorporates a 0.2 mm LuAG:Ce scintillator. Tungsten carbide is a machinable high-Z material which at millimetre thicknesses is opaque to X-rays. With a slight change in pinhole design, similar to that already in place at the ESRF, tungsten carbide blades could offer a well-controlled aperture size for the pinhole camera with simpler assembly. Further to this, improvements to the photon yield of scintillators mean that the new scintillator GAGG+ has an almost two fold increase in yield compared to the current LuAG: Ce scintillator. An evaluation of the tungsten carbide blades and GAGG+ scintillator is presented.}},
