Description
The IFMIF-DONES facility requires high-performance BPM electronics capable of providing accurate beam position and intensity measurements while ensuring seamless integration with the facility-wide control and synchronization infrastructure. The joint venture AVS-BTESA, leading the DONES-VATIAC contract with CDTI*, subcontracted SAFRAN for the development of a new BPM electronics architecture to support the validation of accelerator control technologies for future IFMIF-DONES installations.
Based on a modular uTCA platform, the solution includes an AMC for high-speed digital processing and an RTM for analog front-end functions. FPGA-based digital signal processing enables direct RF acquisition and flexible implementation of beam diagnostics algorithms. The BPM electronics supports two complementary synchronization approaches: reference to facility RF signal and compatibility with White Rabbit technology for high-precision timing distribution and event timestamping.
This poster highlights the BPM electronics capability to simultaneously acquire the fundamental and second beam harmonics, which are subsequently separated using digital filtering techniques.
This approach enables flexible operation and facilitates comparative studies between harmonics without requiring hardware reconfiguration. The system also incorporates self-calibration capabilities to improve measurement stability and reduce drifts.
