Status of ESS linac upgrade studies for ESSnuSB
/ Gålnander, Björn (ESS, Lund) ; Collins, Max (Lund U. (main)) ; Eshraqi, Mohammad (ESS, Lund) ; Farricker, Aaron (CERN) ; Martins, Carlos (ESS, Lund) ; Miyamoto, Ryoichi (ESS, Lund)
The European Spallation Source (ESS), currently under construction in Lund, Sweden, is the world's most powerful neutron spallation source, with an average power of 5 MW at 2.0 GeV. In the ESS neutrino Super Beam Project (ESSnuSB) it is proposed to utilise this powerful accelerator as a proton driver for a neutrino beam that will be sent to a large underground Cherenkov detector in Garpenberg, mid-Sweden.

The BRAN luminosity detectors for the LHC
/ Matis, Howard S. (LBNL, Berkeley) ; Placidi, Massimo (LBNL, Berkeley) ; Ratti, Alessandro (LBNL, Berkeley) ; Turner, William C. (LBNL, Berkeley) ; Bravin, Enrico (CERN) ; Miyamoto, Ryoichi (ESS, Lund)
This paper describes the several phases which led, from the conceptual design, prototyping, construction and tests with beam, to the installation and operation of the BRAN (Beam RAte of Neutrals) relative luminosity monitors for the LHC. The detectors have been operating since 2009 to contribute, optimize and maintain the accelerator performance in the two high luminosity interaction regions (IR), the IR1 (ATLAS) and the IR5 (CMS).

The opportunity offered by the ESSnuSB project to exploit the larger leptonic CP violation signal at the second oscillation maximum and the requirements of this project on the ESS accelerator complex
/ Wildner, Elena (CERN) ; Baussan, E. (Strasbourg, IPHC) ; Blennow, M. (Royal Inst. Tech., Stockholm) ; Bogomilov, M. (Sofiya U.) ; Burgman, A. (Lund U.) ; Bouquerel, E. (Strasbourg, IPHC) ; Carlile, C. (Uppsala U.) ; Cederkäll, J. (Lund U.) ; Christiansen, P. (Lund U.) ; Cupial, P. (AGH-UST, Cracow) et al.
Very intense neutrino beams and large neutrino detectors will be needed to enable the discovery of CP violation in the leptonic sector. The European Spallation Source (ESS), currently under construction in Lund, Sweden, is a research center that will provide, by 2023, the world's most powerful neutron source. [...]

In high brightness colliders, the tune spread due to the collisions has a significant impact on the quality of the beams. The impact of the working point on emittance growth and beam lifetime has been observed in beam experiments in LHC. [...]

Operational Results of the LHC Luminosity Monitors until LS1
/ Ratti, Alessandro (LBNL, Berkeley) ; Hedges, Samuel (LBNL, Berkeley) ; Jones, John (LBNL, Berkeley) ; Matis, Howard (LBNL, Berkeley) ; Placidi, Massimo (LBNL, Berkeley) ; Turner, William (LBNL, Berkeley) ; Vytla, Vamsi (LBNL, Berkeley) ; Bravin, Enrico (CERN) ; Roncarolo, Federico (CERN) ; Miyamoto, Ryoichi (ESS, Lund)
The monitors for the high luminosity regions in the LHC have been operating since 2009 to optimize the LHC's luminosity. The devices are gas ionization chambers inside the neutral particle absorber 140 m from the interaction point and monitor showers produced by high energy neutral particles from the collisions. [...]

Automatic Correction of Betatron Coupling in the LHC Using Injection Oscillations

The control of the betatron coupling at injection and during the energy ramp is critical for the safe operation of the tune feedback and for the dynamic aperture. In the LHC every fill is preceded by the injection of a pilot bunch with low intensity. [...]
