As many other synchrotron light sources, ALBA is also going through an upgrade phase. One of the challenge is the miniaturization of many components among which BPMs.
In this contribution the development of BPMs for ALBA II from the design to the prototyping will be presented.
To ensure the optimal performance of BPMs in synchrotron rings, particularly in PETRA IV, it is important to fully understand the evaluation process of individual feedthroughs and fully assembled BPMs. This involves grouping feedthroughs into sets of four with similar electrical properties and then, after assembling them into a complete BPM device, checking the electrical and mechanical...
In order to accommodate the ever increasing expectations of the users, several third-generation Synchrotron light source facilities are going to be upgraded to the fourth-generation.
To achieve the target performance of such new machines, the design and validation stages related to the beam position monitor detectors have to be deeply investigated through numerical tools such as CST Particle...
Since the beginning of the ESRF-EBS storage ring in 2020, 11 BPM are affected by a phenomenon which generates un-physical position measurements, which depends on some beam parameter (mostly filling pattern and total current).
This issue is probably arising from a RF resonance at the BPM measurement frequency (352 MHz) present in the vicinity of the BPM block, inside the vacuum chamber....
