Abstract: The Compressed Baryonic Matter (CBM) experiment* is currently under construction at the Facility for Antiproton and Ion Research (FAIR) in Darmstadt. The aim of the experiment is the exploration of the Quantum Chromodynamics (QCD) phase diagram of matter at high net-baryon densities and for moderate temperatures. In this contribution a beam monitoring (BMON) system will be presented which will include a high-speed time-zero (T0) detector. The detector system must meet the requirements of the CBM time-of-flight (ToF) measurement system for proton and heavy-ion beams and should also allow for beam monitoring. The detector technology is planned to be based on chemical vapor deposition (CVD) diamond basis but also new Low Gain Avalanche Detector (LGAD) developments are evaluated. In this contribution the beam detector concept will be presented and the results of first prototype tests in the mini-CBM setup will be shown.
