New RF BPM Electronics for the 560 Beam Position Monitors of the APS-U Storage Ring

With the upgrade of the APS storage ring to a multi-bend achromat lattice, 560 RF Beam Position Monitors (BPMs) will be required. The projected beam sizes are below 10 microns in both horizontal and vertical planes, putting stringent requirements on the BPM electronics resolution, long-term stability, beam current dependency and instrument reproducibility. For the APS-U project, the Libera Brilliance+ instrument has been upgraded in technology and capabilities, including the addition of independent multi-bunch turn-byturn processing and an improved algorithm to further reduce artifacts of the crossbarswitch. More than 140 instruments, equipped with 4 BPM electronics modules each, are being delivered to Argonne National Laboratory, consisting the largest scale production for Instrumentation Technologies. In this contribution, the extensive test-conditions to which the instruments were exposed and their results will be presented, as well as the beambased long-term drift measurements with different fill patterns.
