SuperKEKB is an electron–positron double ring collider that aims to achieve a peak luminosity of 8 x 10$^{35}$ cm$^{-2}$ s$^{-1}$ by using what is known as the “nano-beam” scheme. A luminosity dither system is employed for collision orbit feedback in the horizontal plane. [...]

Measurement of Satellite Bunches at the LHC

The RF gymnastics involved in the delivery of proton and lead ion bunches to the LHC can result in satellite bunches of varying intensity occupying the nominally empty RF buckets. Quantification of these satellites is crucial for bunch-by-bunch luminosity normalization as well as for machine protection. [...]

First measurements results of the LHC longitudinal density monitor
/ Jeff , A (CERN) ; Andersen, M (CERN) ; Bravin, E (CERN) ; Boccardi, A (CERN) ; Bozyigit, S (CERN) ; Lefevre, T (CERN) ; Rabiller, A (CERN) ; Roncarolo, F (CERN) ; Welsch, C P (Cockcroft Inst. Accel. Sci. Tech.) ; Fisher, A S (SLAC)
Knowledge of the longitudinal distribution of particles is important for various aspects of accelerator operation, for example to check the injection quality and to characterize the development of ghost bunches before and during the physics periods. A new detector, the LHC Longitudinal Density Monitor (LDM) is a single-photon counting system measuring synchrotron light by means of an avalanche photodiode detector. [...]
