Experiments with high-intensity heavy ion beams require fast and radiation-hard beam detection systems. For these purposes, chemical vapor deposition (CVD) diamond sensors are widely used. Its radiation hardness and excellent timing characteristics make the diamond material an almost ideal choice for in-beam applications.
A beam detector system (BMON) based on poly-crystal CVD diamond technology has been developed for the CBM experiment at the FAIR accelerator complex. The system will be used for T0 measurements with a time precision of 50 ps and for beam monitoring purposes.
For the upcoming HADES beamtimes at the SIS18 accelerator, a T0 and veto system has been developed and installed, which is based on pcCVD diamond sensors.
This contribution will present the CBM BMON concept and the current status of the project. Furthermore, the HADES T0 and veto system will be introduced, and first insights into its performance will be shown.
