Quasi-Strong-Strong Beam-Beam Modeling of Bootstrapping Injection in FCC-ee

Frank Zimmermann, Katsunobu Oide, Takashi Mori

Quasi-strong-strong simulations identify stable bootstrapping injection up to nominal bunch population in W and H modes of FCC-ee but saturation below nominal in Z mode.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Stable injection paths up to the nominal bunch population are identified in the W and H modes. In contrast, in the explored parameter region, the Z mode exhibits saturation of the stored population below the nominal value.

C2weakest assumption

The quasi-strong-strong coupling of paired weak-strong simulations accurately preserves the self-consistent beam-beam lens under charge imbalance during gradual bunch population increase.

C3one line summary

Quasi-strong-strong simulations identify stable bootstrapping injection up to nominal bunch population in W and H modes of FCC-ee but saturation below nominal in Z mode.
