Limits of chromaticity correction

The LHC luminosity upgrade supposes from the point of view of the optics the upgrade of the Interaction Regions (IR) of the main experiments ATLAS and CMS. This upgrade is expected to provide a 􀀀 of 25 cm instead of the 50 cm of the nominal one. This decreasing in 􀀀 implies an increasing of the maxi...

Sumario:The LHC luminosity upgrade supposes from the point of view of the optics the upgrade of the Interaction Regions (IR) of the main experiments ATLAS and CMS. This upgrade is expected to provide a 􀀀 of 25 cm instead of the 50 cm of the nominal one. This decreasing in 􀀀 implies an increasing of the maximum 􀀀in the low-􀀀quadrupoles and subsequently a more dif cult chromaticity correction. In this report we analyze ¡the limits and possible strategies on the chromaticity correction for the different optics proposed for the upgrade of the IR.
