In order to minimize the latency of Sirius Fast Orbit Feedback (FOFB), a 12-channel current source power supply was designed as a μRTM module. Each channel consists of a linear amplifier operating as current source by means of a digital feedback loop implemented on an FPGA at the AMC board. The amplifier is specified to reach up to 10 kHz small-signal bandwidth on a 3.5 mH...
In the scope of the TDR phase for the future PETRA IV low-emittance ring upgrade project, special attention is being dedicated to the prototyping of the future BPM electronics. The large machine will use a large number of BPM pickups, around 800, and the requirements for each system will be stringent for what regards resolution, accuracy and long-term stability. To acquire and process all the...
BESSY II operates with special fill patterns that include transversely moving bunches, which should be ignored in the calculation of the beam postion. To enable this, a system of four 1 GS/s ADCs is used to acuire the button amplitudes with the required fidelity. This talk will present the status of our plans, including aspects of MTCA crate, ADC and FPGA selections, as well as sample clock...
BPM electronics at SOLEIL also embed the FOFB communication and computation.
As these electronics come to an obsolescence, we aim at a new orbit feedback system.
A dedicated standalone microTCA based platform is envisioned for this new system. This new architecture composed of cell and central nodes will (among other tasks) collects the BPM data, computes and send to the correctors the...
