A novel X‐ray beam‐position detection device that we call a position‐sensitive photoconductive detector (PSPCD) is designed to have synthetic diamond as its substrate material. We proved that it is feasible to use synthetic diamond to make a hard X‐ray position‐sensitive detector based on the photoconductivity principle and that it acts as a solid‐state ion chamber. Experiments on different PSPCD samples using synthetic diamond with a high‐heat‐flux white undulator beam, as well as with monochromatic hard X‐ray beams, have been performed at the Advanced Photon Source. Recent test results with the PSPCD in the quadrant configuration as an X‐ray beam‐position monitor and in a multipixel array as an X‐ray beam profiler are presented in this paper.
