The two-beam acceleration scheme envisaged for CLIC will require a high degree of phase stability between two beams at the drive beam decelerator sections, to allow efficient acceleration of the main beam. There will be up to 48 such decelerator sections for the full 3 TeV design, and each decelerator section will be instrumented with a feed-forward system to correct the drive beam phase to a precision of 0.2 degrees at 12 GHz relative to the main beam, using a kicker system around a four-bend chicane.

Demonstration of CLIC Level Phase Stability using a High Bandwidth, Low Latency Drive Beam Phase Feedforward System at the CLIC Test Facility CTF3
/ Roberts, Jack (Oxford U., JAI ; CERN) ; Andersson, Alexandra (CERN) ; Burrows, Philip (Oxford U., JAI) ; Christian, Glenn (Oxford U., JAI) ; Corsini, Roberto (CERN) ; Ghigo, Andrea (Frascati) ; Marcellini, Fabio (Frascati) ; Perry, Colin (Oxford U., JAI) ; Skowroński, Piotr (CERN)
The CLIC acceleration scheme, in which the RF power used to accelerate the main high energy beam is extracted from a second high intensity but low energy beam, places strict requirements on the phase stability of the power producing drive beam. To limit luminosity loss caused by energy jitter leading to emittance growth in the final focus to below 1%, 0.2 degrees of 12 GHz, or 50 fs, drive beam phase stability is needed. [...]

First Results From Beam Tests of the CLIC Drive Beam Phase Feedforward Prototype at CTF3

In the CLIC two beam acceleration scheme 100 MV/m normal conducting cavities are fed with RF power extracted from a secondary high power but low energy drive beam. To ensure the efficiency and luminosity performance of CLIC the phase synchronisation between the high energy main beam and the drive beam must be maintained to within 0.2 degrees of 12 GHz. [...]

Design, Hardware Tests and First Results From the CLIC Drive Beam Phase Feed-Forward Prototype at CTF3
/ Roberts, Jack (CERN ; Oxford U., JAI) ; Andersson, Alexandra (CERN) ; Skowronski, Piotr K (CERN) ; Burrows, Philip N (Oxford U., JAI) ; Christian, Glenn B (Oxford U., JAI) ; Perry, Colin (Oxford U., JAI) ; Ghigo, Andrea (INFN, LNS) ; Marcellini, Fabio (INFN, LNS)
In the CLIC two beam acceleration concept the phase synchronisation between the main beam and the RF power extracted from the drive beam must be maintained to within 0.2 degrees of 12 GHz. A drive beam phase feed-forward system with bandwidth above 17.5 MHz is required to reduce the drive beam phase jitter to this level. [...]

Commissioning experience and first results from the new SLS beam size monitor
/ Schlott, V (PSI, Villigen) ; Rohrer, M (PSI, Villigen) ; Saa Hernandez, A (PSI, Villigen) ; Streun, A (PSI, Villigen) ; Andersson, A (MaxLab) ; Breunlin, J (Lund U., MAX-lab) ; Milas, N (LNLS, Campinas)
In the context of the TIARA work package “SLS vertical emittance tuning” (SVET), an extremely small vertical beam size of 3.6 $\mu$m, corresponding to a vertical emittance of 0.9 pm, was verified using an optical monitor based on imaging of $\pi$-polarized light. Since the existing beam size monitor reached its limit of resolution, a new monitor beam line was designed and installed at the 08BD bending magnet of the Swiss Light Source (SLS) storage ring. [...]
