In 2017, PSI started a research activity to develop x-ray beam position monitors (XBPM) based on Silicon Carbide thin membranes.  Original goal of the project was to resolve material limits associated to polycrystalline diamond based XBPMs like low yields, low uniformities, and poor electrical responses in terms of time resolution and amplitude of the signal.

In these two years of development the original goal greatly enlarged, encompassing novel beam monitoring applications, beyond those of both polycrystalline and single crystal diamonds.

During the presentation a complete overview of the current status of the activity will be given, focusing not only on well-established fields like monochromatic hard x-ray beam monitoring, with several established and planned installations, but also on novel applications: monitoring of (i) transmitted, (ii) polychromatic (pink and white beams) and (iii) soft x-ray beams, compact dosimeters, near-sample monitors and more.
