Description
Because of the strong beam-beam force at the interaction points in FCC-ee, the charge balance of two beams opposing each other is vitally important.
The injection of a high charge beam derives the imbalance of two beams, which causes the instability of the beams.
To avoid this imbalance, the bootstrapping injection has been adopted for the FCC-ee collider.
The conditioning of the bootstrapping injection is being performed as a part of the design study of FCC-ee.
For simulating the top-up injection, the quasi-strong-strong beam-beam calculation is implemented in the full lattice simulation code SAD.
In this report, the current status of the quasi-strong-strong simulation status are presented.
