| Popis: |
Amplitude detuning measurements in the LHC have shown that a significant amount of detuning is generated via feed-down from high-order field errors in the magnets of the experiment insertion regions. This undesired effect can be detrimental to the luminosity production of the machine and is expected to be enhanced in the upcoming high-luminosity upgrade of the collider, the HL-LHC. In this study, we investigate the high-order errors in detail, performing amplitude detuning measurements during the commissioning of the LHC Run 3 and establish operational corrections via feed-down, using for the first time the dodecapole correctors in the insertion region. |
