The BBQ tune (Q) and chromaticity (Q’) diagnostic systems played a crucial role during the LHC commissioning while establishing circulating beam and first ramps. Early on, they allowed identifying issues such as residual tune stability, beam spectr

The LHC deploys a comprehensive suite of beam-based feedbacks for safe and reliable machine operation. This contribution summarises the commissioning and early results of the LHC feedback control systems on orbit, tune, chromaticity, and energy. Thei

A high resolution beam position monitor (BPM) electronics based on diode peak detectors has been developed at CERN. The circuit processes the BPM electrode signals independently, converting the short beam pulses into slowly varying signals which can

This note summarises the performance and early results obtained with the base-line LHC Tune Measurements System during the first days of LHC operation. Initial tune, coupling and chromaticity measurements as well as initial tune correction are presen
