MD2148: Flat optics
This note reports on the first attempt to measure and correct optics errors at β∗=60/30 cm and β∗=60/15 cm flat optics. In the absence of the Beam 2 vertical AC dipole, the ADT was used in AC-dipole mode to verify local corrections in IR1. A peak β-beating of 24% remained after global corrections in t...

| description | This note reports on the first attempt to measure and correct optics errors at β∗=60/30 cm and β∗=60/15 cm flat optics. In the absence of the Beam 2 vertical AC dipole, the ADT was used in AC-dipole mode to verify local corrections in IR1. A peak β-beating of 24% remained after global corrections in the horizontal plane of arc 45 of Beam 1. β∗ measurements with K-modulation showed a peak β∗-beating of 16% or larger, as IP1 measurement could not be completed. Global corrections for Beam 2 were also computed. |
