Description of beam instabilities in synchrotrons with wakefields and space charge forces using the circulant matrix model
/ Buffat, X (CERN) ; Métral, E (CERN) ; Gottlob, E (Ecole Polytechnique, Lausanne ; U. Brussels (main)) ; Høgh, C (Ecole Polytechnique, Lausanne ; Imperial Coll., London) ; Oeftiger, A (Darmstadt, GSI ; CERN) ; Pieloni, T (Ecole Polytechnique, Lausanne)
A new model for the description of beam instabilities in synchrotrons featuring wakefields and space charge forces is proposed, using the circulant matrix approach. The predictions of this model are discussed in light of past ones, with a particular emphasis on the possible mitigation of the transverse mode coupling instability by space charge forces. [...]

Considerations for a RF separated K+ beam for NA62
/ Appleby, Robert Barrie (University of Manchester (GB)) ; Bernhard, Johannes (CERN) ; Dainton, John Bourke (Lancaster University (GB)) ; Burt, Graeme Campbell (Lancaster University (GB)) ; Gatignon, Lau (Lancaster University (GB)) ; Goudzovski, Evgueni (University of Birmingham (GB)) ; Jones, Rhodri (CERN) ; Lazzeroni, Cristina (University of Birmingham (GB)) ; Romano, Angela (University of Birmingham (GB)) ; Giuseppe, Ruggiero (Dipartimento di Fisica e Astronomia) et al.
In this document we assess the potential of RF separation to increase the kaon content of the high-intensity secondary beam to the NA62 experiment in the CERN North Area. The present mixed beam provides a nominal kaon flux of 45 MHz out of a total beam intensity of about 750 MHz. [...]

Development and Fabrication of Nb$_3$Sn Rutherford Cable for the 11 T DS Dipole Demonstration Model
/ Barzi, E (Fermilab) ; Lombardo, V (Fermilab) ; Nobrega, F (Fermilab) ; Turrioni, D (Fermilab) ; Yamada, R (Fermilab) ; Zlobin, A V (Fermilab) ; Karppinen, M (CERN)
Fermilab and CERN started the development of 11 T Nb$_3$Sn dipoles 11 m long to replace a few regular LHC NbTi dipoles and free space for cold collimators in LHC dispersion suppression (DS) areas. An important step in the design of these magnets is the development of the high aspect ratio Nb$_3$Sn cable to achieve the nominal field of 11 T at the nominal LHC operating current of 11.85 kA with 20% margin. [...]

Design and Fabrication of a Single-Aperture 11T Nb$_3$Sn Dipole Model for LHC Upgrades
/ Andreev, N (Fermilab) ; Apollinari, G (Fermilab) ; Barzi, E (Fermilab) ; Bossert, R (Fermilab) ; Nobrega, F (Fermilab) ; Novitski, I (Fermilab) ; Turrioni, D (Fermilab) ; Yamada, R (Fermilab) ; Zlobin, A V (Fermilab) ; Auchmann, B (CERN) et al.
The planned upgrade of the LHC collimation system includes additional collimators to be installed in the dispersion suppressor areas of points 2, 3 and 7. To provide the necessary longitudinal space for the collimators, a replacement of 8.33 T Nb-Ti LHC main dipoles with 11 T dipoles based on Nb3Sn superconductor compatible with the LHC lattice and main systems is being considered.

First demonstration of the use of crab cavities on hadron beams

Many future particle colliders require beam crabbing to recover geometric luminosity loss from the nonzero crossing angle at the interaction point (IP). A first demonstration experiment of crabbing with hadron beams was successfully carried out with high energy protons. [...]
