/ Resta-Lopez, J (Valencia U., IFIC) ; Alabau-Gonzalvo, J (Valencia U., IFIC) ; Bett, D R (Oxford U., JAI) ; Burrows, P N (Oxford U., JAI) ; Christian, G B (Oxford U., JAI) ; Davis, M R (Oxford U., JAI) ; Perry, C (Oxford U., JAI) ; Apsimon, R (CERN) ; Constance, B (CERN) ; Gerbershagen, A (CERN)
For future linear colliders the precise control and mitigation of pulse-to-pulse orbit jitter will be very important to achieve the required luminosity. Diagnostic techniques for the orbit jitter measurement and correction for multibunch operation are being addressed at the KEK Accelerator Test Facility 2 (ATF2) [...]

The FONT5 Bunch-by-Bunch Position and Angle Feedback System at ATF2
/ Apsimon, R J (Oxford U., JAI) ; Bett, D R (Oxford U., JAI) ; Burrows, P N (Oxford U., JAI) ; Christian, G B (Oxford U., JAI) ; Constance, B (Oxford U., JAI ; CERN) ; Davis, M R (Oxford U., JAI) ; Gerbershagen, A (Oxford U., JAI ; CERN) ; Perry, C (Oxford U., JAI) ; Resta-Lopez, J (Valencia U., IFIC)
The FONT5 upstream beam-based feedback system at ATF2 is designed to correct the position and angle jitter at the entrance to the ATF2 final-focus system, and also to demonstrate a prototype intra-train feedback system for the International Linear Collider interaction point. We discuss the hardware, from stripline BPMs to kickers, and RF and digital signal processing, as well as presenting results from the latest beam tests at ATF2..

A prototype ultra-fast beam-based feedback system for deployment in single-pass beamlines, such as a future lepton collider (ILC or CLIC) or a free-electron laser, has been fabricated and is being tested in the extraction and final focus lines of the Accelerator Test Facility (ATF) at KEK. FONT5 is an intra-train feedback system for stabilising the beam orbit via different methods: a position and angle feedback correction in the extraction line or a vertical feedforward correction applied at the interaction point (IP) .
