Sumario: | In this report three separate studies on the topic of orbit correction are presented for the HL–LHC V1.5 layout and 15 cm β∗ optics for protons. It is shown that the constraints put on the error correction for the assumed machine imperfections distribution, together with the implementation of the desired orbit knobs, are compatible with the available corrector strengths. Results based on a simplified model of the present LHC orbit feedback are presented, showcasing its efficiency in maintaining beam collisions and the inherent orbit stability expected in LHC and in HL–LHC. Finally, necessary short-term beam position monitor stability for adequate position-based correction of beam separation is investigated and estimated to be under one micrometre. |
