WP2: Accelerator Physics and Performance
- Develop operational scenarios and layout options in collaboration with the relevant work packages.
- Develop optics and layout configurations and prepare on regular intervals coherent sets and versions of these files in a generally accessible repository.
- Specify the requirements in terms of maximum strength, length, aperture, field quality of the main and correction magnetic elements in collaboration with the relevant work packages.
- Define the requirements in terms of aperture available for the beam and agree tolerances (mechanical, alignment, orbit control, etc.) in collaboration with the relevant work packages.
- Specify the requirements for the powering circuits and performance (ripple, accuracy, precision, etc.) in collaboration with the relevant work packages and the HL-LHC circuit coordinator.
- Define operational cycles for the various machine elements.
- Evaluate intensity limitations resulting from impedance, electron-cloud and beam-beam effects and their interplay and develop mitigation strategies.
- Define the optics measurement and correction strategies and the implications for beam instrumentation and corrector specification.
- Evaluate the overall performance reach in collaboration with the relevant work packages and with the experiments.
