Baseline LHC machine parameters and configuration of the 2015 proton run
R. Bruce, G. Arduini, S. Fartoukh +6
This paper shows the baseline LHC machine parameters for the 2015 start-up. Many systems have been upgraded during LS1 and in 2015 the LHC will operate at a higher energy than befo…
Coherent beam-beam mode in the LHC
X. Buffat, R. Calaga, R. Giachino +4
Observations of single bunch beam-beam coherent modes during dedicated experiments in the LHC are presented. Their role in standard operation for physics is discussed and, in parti…
Operational considerations on the stability of colliding beams
X. Buffat, W. Herr, T. Pieloni
While well studied in the absence of beam-beam and while colliding head-on, the stability of the LHC beams can be very critical in intermediate steps. During the squeeze, the long-…
Luminosity levelling techniques for the LHC
B. Muratori, T. Pieloni
We present the possibilities for doing luminosity levelling at the LHC. We explore the merits and drawbacks of each option and briefly discuss the operational implications. The sim…
Stability diagram of colliding beams
X. Buffat, W. Herr, N. Mounet +1
The effect of the beam-beam interactions on the stability of impedance mode is discussed. The detuning is evaluated by the means of single particle tracking in arbitrarily complex…
Long Range Beam-beam Effects in the LHC
W. Herr, X. Buffat, R. Calaga +4
We report on the experience with long-range beam--beam effects in the LHC, in dedicated studies as well as the experience from operation. Where possible, we compare the observation…
Observations of beam-beam effects at the LHC
G. Papotti, X. Buffat, W. Herr +2
This paper introduces a list of observations related to the beam-beam interaction that were collected over the first years of LHC proton physics operation (2010-12). Beam-beam rela…
