  Artificially-grown diamond crystals have unique properties that make them
suitable as solid-state particle detectors and dosimeters in high-radiation
environments. We have been using sensors based on single-crystal diamond grown
by chemical vapour deposition for dosimetry and beam-loss monitoring at the
SuperKEKB collider. Here we describe the assembly and the suite of test and
calibration procedures adopted to characterise the diamond-based detectors of
this monitoring system. We report the results obtained on 28 detectors and
assess the stability and uniformity of response of these devices.
