A 2 mm width by 2 mm breadth by 0.5 mm thick electronic grade single crystal diamond grown via chemical vapour deposition was configured as a metal–semiconductor–metal X-ray detector. The detector was electrically characterised before it was connected to a bespoke charge-sensitive preamplifier of low-noise. An 55Fe radioisotope X-ray source was used to illuminate the detector with soft (5.9 keV and 6.49 keV) X-rays. The detector and preamplifier were temperature controlled and operated at 20 °C. The energy resolution (full width at half maximum) of the diamond spectrometer was 2.48 keV at 5.9 keV. Shaping time noise analysis conducted on the X-ray spectra found dielectric noise to be the largest electronic noise contribution for all but the shortest of shaping times, when series white noise dominated. To the best of the authors’ knowledge, this is the first report of a diamond detector’s spectroscopic photon counting response to soft (< 10 keV) X-rays.
