Description
This work focuses on the energy calibration of the FCC-ee and aims to develop precise techniques for ensuring accurate beam energy measurements, essential for improving the precision of electroweak parameter determinations. To do so, resonant depolarisation technique will be employed, requiring the continuous operation of a depolariser and Compton polarimeters for both electrons and positrons beam. Extraction of pilot bunches polarization is realized from the spatial distribution of scattered electrons and photons.
The work explores the determination of Compton-scattering parameters. Preliminary conceptual studies of the fitting procedure required for this extraction are presented here. In addition, studies on the fast extraction of bunch polarisation parameters for each turn in the ring are included, aiming to enable faster, turn-by-turn monitoring of the beam polarisation.
