	A new fast orbit feedback (FOFB) hardware architecture has been pursued at Sirius. The fast corrector magnets’ are fed by power supply modules which are placed in the same MicroTCA.4 crates where the BPM digitizers and FOFB controllers are located. Each channel is made of a 3-Watt linear amplifier whose output currents are digitally controlled by the same FPGA where the distributed orbit feedback controller is processed. The amplifier is specified to reach up to 10 kHz small-signal bandwidth on a 3.5 mH inductance magnet and ±1 A full scale, which translates to 30 urad deflection on Sirius’ 3 GeV beam. Such a high level of integration aims at minimizing the overall latency of the FOFB loop while leveraging the crate infrastructure, namely electronics enclosure, DC power, cooling, and hardware management support already provided by the MTCA.4 crates. The fast corrector power supply channels are placed on Rear Transition Modules (RTMs) which are attached to the front AMC FPGA module where the FOFB controller is implemented. This paper will describe the main design concepts and report on the experimental results of the first prototypes.

A new fast orbit feedback (FOFB) hardware architecture has been pursued at Sirius. The fast corrector magnets’ are fed by power supply modules which are placed in the same MicroTCA.4 crates where the BPM digitizers and FOFB controllers are located. Each channel is made of a 3-Watt linear amplifier whose output currents are digitally controlled by the same FPGA where the distributed orbit feedback controller is processed. The amplifier is specified to reach up to 10 kHz small-signal bandwidth on a 3.5 mH inductance magnet and ±1 A full scale, which translates to 30 urad deflection on Sirius’ 3 GeV beam. Such a high level of integration aims at minimizing the overall latency of the FOFB loop while leveraging the crate infrastructure, namely electronics enclosure, DC power, cooling, and hardware management support already provided by the MTCA.4 crates. The fast corrector power supply channels are placed on Rear Transition Modules (RTMs) which are attached to the front AMC FPGA module where the FOFB controller is implemented. This paper will describe the main design concepts and report on the experimental results of the first prototypes.
