/ Tomás, R (CERN) ; Kubo, K (KEK Japan) ; Kuroda, S (KEK Japan) ; Naito, T (KEK Japan) ; Okugi, T (KEK Japan) ; Urakawa, J (KEK Japan) ; Zimmermann, F (CERN)
The measurement of resonance driving terms in the Damping Ring of the Accelerator Test Facility in KEK could help finding possible machine imperfections and even to optimize single particle stability through the minimization of non-linearities. The first experimental attempts of this enterprise are reported in this note..

CERN SPS Impedance in 2007

Each year several measurements of the beam coupling impedance are performed in both longitudinal and transverse planes of the CERN Super Proton Synchrotron to keep track of its evolution. In parallel, after the extensive and successful campaign of identification, classification and cure of the possible sources of (mainly longitudinal) impedance between 1998 and 2001, a new campaign (essentially for the transverse impedance this time) has started few years ago, in view of the operation of the SPS with higher intensity for the LHC luminosity upgrade.

Beam Losses and Collimation Considerations for PS2
/ Barranco, J (CERN) ; Bartmann, W (CERN) ; Benedikt, M (CERN) ; Papaphilippou, Y (CERN)
The high intensity beams with different emittances foreseen to be delivered by the PS2, an upgraded version of the actual CERN Proton Synchrotron, require strict control of beam losses in order to protect the machine components and enable their hands-on maintenance. Beam loss simulations based on dedicated numerical tools are undertaken for a variety of PS2 beams and for different loss mechanisms, along the whole accelerating cycle. [...]

Alignment of the CLIC BDS
/ Latina, A (CERN) ; Schulte, D (CERN) ; Tomás, R (CERN)
Aligning the CLIC Beam Delivery System faces two major challenges, the tight tolerances for the emittance preservation and its strong non-linear beam dynamics. For these reasons conventional beam-based alignment techniques, like dispersion free steering, are only partially successful and need to be followed by optimization algorithms based on other observables, like beam sizes..

Transverse Mode-Coupling Instability in the CERN SPS : Comparing Moses Analytical Calculations and Headtail Simulations with experiments in the SPS

Since 2003, single bunches of protons with high intensity (1.2e11 protons) and low longitudinal emittance (0.2 eVs) have been observed to suffer from heavy losses in less than one synchrotron period after injection at 26 GeV/c in the CERN Super Proton Synchrotron (SPS) when the vertical chromaticity is corrected. Understanding the mechanisms underlying this instability is crucial to assess the feasibility of an anticipated upgrade of the SPS, which requires bunches of 4e11 protons. [...]

The electron cloud instability limits the performance of many existing proton and positron rings. A simulation study carried out with the HEADTAIL code revealed that the threshold for its onset decreases with increasing beam energy, if the 6D emittance of the bunch is kept constant and the longitudinal matching to the bucket is preserved.

Adiabaticity and Reversibility Studies for Beam Splitting using Stable Resonances

At the CERN Proton Synchrotron, a series of beam experiments proved beam splitting by crossing the one-fourth resonance. Depending on the speed at which the horizontal resonance is crossed, the splitting process is more or less adiabatic, and a different fraction of the initial beam is trapped in the islands. [...]

Parameter Scan for the CLIC Damping Rings
/ Papaphilippou, Y (CERN) ; Braun, H H (CERN) ; Korostelev, M (Cockroft Inst.)
Triggered by the RF frequency reduction of the CLIC main linac cavities, the damping ring parameters had to be reevaluated and the rings performance adapted to the new luminosity requirements. In view of a staged approach for reaching the ultimate energy of the collider, the dependence of the rings output emittances under the influence of Intrabeam Scattering is evaluated with respect to different beam characteristics such as bunch population, beam energy, coupling and longitudinal beam characteristics..

This paper presents technical considerations and potential parameter choices for such a machine and outlines some of the challenges arising when an electron storage ring based option, constructed within the existing infrastructure of the LHC, is chosen..

The Merit(nTOF-11) High Intensity Liquid Mercury Target Experiment at the CERN PS
/ Efthymiopoulos, I (CERN) ; Bennett, J R J (Rutherford) ; Caretta, O (Rutherford) ; Carroll, A J (Oak Ridge) ; Fabich, A (CERN) ; Graves, V B (Oak Ridge) ; Grudiev, A (CERN) ; Haug, F (CERN) ; Kirk, H G (Brookhaven) ; Lettry, Jacques (CERN) et al.
The MERIT(nTOF-11) experiment is a proof-ofprinciple test of a target system for a high power proton beam to be used as front-end for a neutrino factory or a muon collider. The experiment took data in autumn 2007 with the fast-extracted beam from the CERN Proton Synchrotron (PS) to a maximum intensity of $30 × 10^{12}$ per pulse. [...]

Development, Production and Testing of 4500 Beam Loss Monitors
/ Holzer, E B (CERN) ; Chiggiato, P (CERN) ; Dehning, B (CERN) ; Ferioli, G (CERN) ; Grishin, V (Serpukhov, IHEP) ; Jimenez, T M (CERN) ; Koshelev, A (Serpukhov, IHEP) ; Kramer, Daniel (CERN) ; Larionov, A (Serpukhov, IHEP) ; Taborelli, M (CERN) et al.
Beam-loss monitoring (BLM) [1] is a key element in the LHC machine protection. 4250 nitrogen filled ionization chambers (IC) and 350 secondary emission monitors (SEM) have been manufactured and tested at the Institute for High Energy Physics (IHEP) in Protvino, Russia, following their development at CERN.

Development of an Eddy Current Septum for LINAC4
/ Barnes, M (CERN) ; Balhan, B (CERN) ; Borburgh, J (CERN) ; Fowler, T (CERN) ; Goddard, B (CERN) ; Ueda, A (KEK Japan) ; Weterings, W (CERN)
A linear accelerator (linac) is the first stage of the CERN accelerator complex. The linac defines the beam quality for subsequent stages of acceleration and the reliability has to be high as a fault of the linac shuts down all other machines. [...]

Upgrading the Fast Extractions Kicker System in SPS LSS6
/ Barnes, M (CERN) ; Ducimetière, L (CERN) ; Goddard, B (CERN) ; Uythoven, J (CERN)
A fast extraction system, located in the LSS6 region of the CERN SPS accelerator, transfers 450 GeV/c protons, as well as ions, via the TI 2 transfer line towards the LHC. The system includes three travelling wave kicker magnets, all powered in series, energised by a single Pulse Forming Network (PFN) and terminated by a short circuit. [...]

Ions for LHC : Towards Completion of the Injector Chain
/ Manglunki, Django (CERN) ; Albert, M (CERN) ; Angoletta, M E (CERN) ; Arduini, Gianluigi (CERN) ; Baudrenghien, P (CERN) ; Bellodi, G (CERN) ; Belochitskii, P (CERN) ; Benedetto, E (CERN) ; Bohl, T (CERN) ; Carli, C (CERN) et al.
The commissioning of CERN's ion injector complex [1] to allow 1.1 PeV collisions of ions in LHC is well under way. After the Low Energy Ion Ring (LEIR) in 2005 [2] and the Proton Synchrotron (PS) in 2006 [3], the Super Proton Synchrotron (SPS) has now been commissioned with the 'Early' ion beam, which should give a luminosity of $5×10^{25}cm^{-2}s^{-1}$ in the LHC.
