Description

In order to explore potential improvements to the current lattice design for FCC-ee, this work looks at the use of Combined Function Magnets (CFM) within the short straight sections of the arc cells. The use of CFMs introduces a change in the damping partition numbers. To avoid this it is necessary to maintain the values of the Synchrotron Radiation Integrals (I2 and I4), which are used to describe the effects of Synchrotron Radiation (SR). New optics solutions are explored to achieve this. SR power could be reduced by 17%. The explored optical solutions could be applied both for normal conducting CFMs and High Temperature Superconductors (HTS).
