The upcoming PETRA IV project at DESY, Germany, represents a new generation of diffraction-limited light sources with ultra-low emittance. A crucial component of the beam diagnostic system for this project is the beam position monitors (BPMs), which will be used for transverse beam position measurements. Approximately 800 of these BPMs will be placed throughout the 2.3 km storage ring. To...
In order to fulfill the target performance of Elettra 2.0 light source, a brand new button type beam position monitor detector has been developed.
In this contribution, a series of practical design considerations involving electromagnetic, mechanical, vacuum, maintenance, and cost issues are reported to illustrate the advantages and disadvantages of the conceived constructive solutions.
The original BPMs in BESSY II with 25 year operational use will be upgraded to Libera Spark. In a first stage we plan for a seemless exchange of BPMs in small sets, ensuring continuous operation with the existing SOFB and FOFB systems while enabling short upgrade periods. In a second stage, we plan to migrate the SOFB and FOFB systems. At this stage we will be able to increase the data rates...
