/ Gamba, Davide (CERN) ; Constance, Ben (CERN) ; Corsini, Roberto (CERN) ; Döbert, Steffen (CERN) ; Malina, Lukas (CERN) ; Martin, Lucy (JAI, UK) ; Peirson Serratosa, Abel (Oxford U.) ; Persson, Tobias (CERN) ; Roberts, Jack (CERN) ; Rollings, Alexandra (CERN) et al.
One of the objective of the CLIC Test Facility (CTF3) at CERN is to demonstrate the CLIC Drive Beam Recombination concept. An accurate control of the transverse beam parameters is necessary in order to succeed in preserving the beam quality after the recombination. [...]

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..

Latest Performance Results from the FONT 5 Intra Train Beam Position Feedback System at ATF
/ Davis, Michael (Oxford U., JAI) ; Bett, Douglas (Oxford U., JAI) ; Blaskovic Kraljevic, Neven (Oxford U., JAI) ; Burrows, Philip (Oxford U., JAI) ; Christian, Glenn (Oxford U., JAI) ; Kim, YoungIm (Oxford U., JAI) ; Perry, Colin (Oxford U., JAI) ; Apsimon, Robert (CERN) ; Constance, Ben (CERN) ; Gerbershagen, Alexander (CERN)
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) .

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) [...]

Recent Improvements to the Control of the CTF3 High-Current Drive Beam
/ Constance, B (CERN) ; Corsini, R (CERN) ; Gamba, D (CERN) ; Skowronski, P K (CERN)
In order to demonstrate the feasibility of the CLIC multiTeV linear collider option, the drive beam complex at the CLIC Test Facility (CTF3) at CERN is providing highcurrent electron pulses for a number of related experiments. By means of a system of electron pulse compression and bunch frequency multiplication, a fully loaded, 120 MeV linac is used to generate 140 ns electron pulses of around 28 Amperes. [...]
