Optics measurement and correction close to the half integer resonance

This paper reports on the first successful attempt to measure and correct the on-momentum optics close to the half integer resonance in LHC at injection energy. This tune working point is traditionally preferred by colliders for providing the largest resonance-free space in the tune diagram [1, 2]....

Sumario:This paper reports on the first successful attempt to measure and correct the on-momentum optics close to the half integer resonance in LHC at injection energy. This tune working point is traditionally preferred by colliders for providing the largest resonance-free space in the tune diagram [1, 2]. It is also considered as an option for the HL-LHC upgrade [3].
