Orbit feedback
WebOct 1, 2024 · Introduction. NSLS-II is a third-generation 3 GeV storage ring with ultra-low emittance. The low emittance requires a stable electron beam orbit that is < 10% of the beam size, in the submicron range. Since the facility was commissioned in 2015, a fast orbit feedback (FOFB) system has been implemented. Weborbit feedback calculation time budget. For NSLS-II s 10KHz fast orbit feedback, the total time budget is 100us. Besides the orbit feedback calculation, much time should be reserved for data communication: distributing all 240 BPM data around the 800 meter ring and sending setpoints to 90 fast correctors around the ring.

WebOct 1, 2024 · This paper discusses improvements made to the fast orbit feedback (FOFB) system at NSLS-II in 2024. We first characterized the system by measuring the transfer function and the closed-loop gain of the system. We also constructed a model to predict the performance, which was based on physical behaviors. Web1 day ago · Virgin Orbit was founded in 2024 to provide a launch service for smaller satellites.
