High-resolution, low-latency, bunch-by-bunch feedback system for nanobeam stabilization
/ Bett, D.R. (JAI, UK ; CERN) ; Blaskovic Kraljevic, N. (JAI, UK ; Lund U., MAX-lab) ; Bromwich, T. (JAI, UK ; Edinburgh U.) ; Burrows, P.N. (JAI, UK) ; Christian, G.B. (JAI, UK ; Diamond Light Source) ; Perry, C. (JAI, UK) ; Ramjiawan, R. (JAI, UK ; CERN)
We report the design, operation and performance of a high-resolution, low-latency, bunch-by-bunch feedback system for nano-beam stabilisation. The system employs novel, ultra-low quality-factor cavity beam position monitors (BPMs), a two-stage analogue signal down-mixing system, and a digital signal processing and feedback board incorporating an FPGA.

A low-latency, intra-train, beam feedback system utilising a cavity beam position monitor (BPM) has been developed and tested at the final focus of the Accelerator Test Facility (ATF2) at KEK. A low-Q cavity BPM was utilised with custom signal processing electronics, designed for low latency and optimal position resolution, to provide an input beam position signal to the feedback system.

A low-latency, sub-micron resolution stripline beam position monitoring (BPM) system has been developed and tested with beam at the KEK Accelerator Test Facility (ATF2), where it has been used to drive a beam stabilisation system. The fast analogue front-end signal processor is based on a single-stage radio-frequency down-mixer, with a measured latency of 16 ns and a demonstrated single-pass beam position resolution of below 300 nm using a beam with a bunch charge of approximately 1 nC.
