Robotic solution for BLM detector maintenance in high radiation areas
189
CERN’s Beam Loss Monitoring (BLM) system is essential for the protection of machine elements against energy deposition due to beam losses. The protection function relies on approximately 5000 ionisation chamber type detectors installed along all of CERN's accelerators. Some of the areas where the detectors are installed have a high background dose (above 2mSv/h). Installation and maintenance times must be minimised to ensure person-nel safety. For this reason, a new solution was designed that allows the manipulation of detectors and their sup-ports by robotic action. Every aspect of the solution has been designed to reduce intervention time, using a rapid locking mechanism and the possibility of transporting the material by robot. The paper presents the design, prototype characterisation results, identified issues, and mitigation methods developed for the automated manipulation of these detectors.

Real-time embedded feedforward correction for SIRIUS undulators
428
SIRIUS, the Brazilian 4th generation synchrotron light source, has been in operation since 2020. Over time, insertion devices (IDs) are expected to populate its straight sections. To supress edge effects from undulators and support overall beam stability, a feedforward correction system is currently available through EPICS layer for the first installed ID. However, performance could be improved by adopting a lower-level solution with higher actuation rates and reduced jitter. To address this, a new approach has been developed using hardware technology already available: control system nodes based on BeagleBone Black platform, which integrates both embedded linux and dedicated real-time processors within the same SoC. This setup enables current setpoints updates at rates up to 1 kHz and aiming to be scalable. This paper presents an overview of the system's architecture and objectives, first results with IVU and VPU undulators as well as future developments and improvements.

Study of XBPM diagnostic parameters in the TPS frontend
612
The XBPM installed in the TPS frontend determines the center position of the photon beam using four CVD diamond blades. The combination of XBPM and upstream/downstream EBPM readings of the insertion device enables verification of the photon beam’s alignment along the correct trajectory. Significant changes in the beam position or profile, as well as prolonged periods without recalibration, may cause the XBPM measurement data to lose its reliability. Therefore, evaluating the reliability of the XBPM measurement data is of critical importance. By analyzing the deviation between the theoretical and measured blade intensities and calculating the standard deviation of the similarity percentage among the four blades, a reliability indicator is established. The variation of this indicator is analyzed under different conditions and compared with the corresponding Q values.

Button BPM development and prototyping for ALBA II
641
As part of the ongoing ALBA II upgrade, which aims to significantly enhance the performance of the ALBA Synchrotron Light Source, a new design for button Beam Position Monitors (BPMs) is under investigation. In this contribution, we present the results of a characterization study conducted on button prototypes supplied by two different manufacturers. Furthermore, we introduce the preliminary design of an alternative button BPM intended for direct welding to the copper vacuum chamber of the upgraded machine.
