I-Tech and DESY are developing a BPM electronics prototype on MicroTCA.4 platform for Petra IV TDR. The new prototype is based on the Libera Brilliance+ BPM system (LB+), and relies on the knowledge, expertise and maturity level of the ~15 years' worth of LB+ development. While the LB+ is based on the MicroTCA.0 technology, it is not 100% MicroTCA.0 nor MicroTCA.4 compatible, mainly due to the...
Diamond Light Source is preparing to replace the synchrotron injector and storage ring to upgrade the facility into a fourth-generation light source. This new machine, Diamond-II, requires faster beam diagnostics to feed improved feedback systems, enabling a significant reduction in beam emittance. Data rates increasing from 10 kHz to 100 kHz has led us to develop an in-house solution based on...
PETRA IV is the upcoming low-emittance, 6 GeV, fourth generation light source at DESY Hamburg. Fast Orbit Feedback (FOFB) system for PETRA IV is planned to perform orbit correction for the full range of disturbance spectrum, i.e. from quasi-DC up to 1 kHz. A total of 789 beam position monitors (BPMs) and 522 fast correctors will be available. A large Multi-Input Multi-Output (MIMO) system is...
The upgrade of SOLEIL Fast Orbit Feedback is scheduled for 2023. For this project, a new platform based on MTCA is under development, with dedicated FPGA firmware, a custom RTM and a control software stack. To speed up development, we decided to use DESY FWK and ChimeraTK. We will review and comment the status of the several components of this platform.
PETRA IV will be a new, fourth-generation, high-brilliance synchrotron radiation source in the hard X-ray range. To keep the emittance low at high beam current an active feedback system to damp transverse multi-bunch instabilities is required. The particular challenge to the system is the very low-noise, while maintaining high bandwidth, which is defined by the 2 ns bunch spacing.
We present...
Sirius Fast Orbit Feedback (FOFB) system came into regular operation for users in November 2022. Its hardware architecture makes extensive use of MicroTCA.4 resources such as backplane clocks, triggers, multigigabit communication and RTM slot for supplying current to the fast corrector magnets.
An overview of the hardware components of the system, including BPMs, FOFB Controllers and Power...
