In particle physics, accelerators and detectors are continually improved to enhance the precision and functionality of experiments. An important part is to continue to ensure the safety of the experiment under the new conditions. The Large Hadron Collider beauty (LHCb) detector was upgraded for the data-taking period beginning in 2022. As part of the upgrade, the Beam Conditions Monitor (BCM), the safety system of the LHCb experiment, got new readout hardware: the Machine Interface Beam Abort Decision system. In addition, a new detector is planned to enhance the beam-monitoring capabilities at the experiment. The Timepix4 telescope is used as a prototype for this detector.

In this work, the control system of both detectors is fully implemented. For the BCM, the focus is on the integration of the new MIBAD system, operating since June 2023. For the Timepix4 telescope, the focus is on the reusability of the components for the future beam-monitoring detector. Finally, beam losses are studied, which can damage the LHCb detector and contribute to a machine-induced background. The losses are characterised, and the contribution to the physics operations is discussed.
