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, the resonant depolarisation technique will be employed, requiring the continuous operation of a depolariser and Compton polarimeters for both electron and positron beams. Extraction of pilot bunches polarization is realized from the spatial distribution of scattered electrons and photons. Preliminary, conceptual investigations of the fitting procedure for this extraction are shown here. The study explores the extraction of Compton scattering parameters under different configurations, corresponding to different realistic integration scenarii. In addition to these preliminary investigations, the work focuses on more realistic studies involving the implementation of a possible detector, aiming to evaluate the polarimeter performance in integrated conditions closer to the final experimental setup.
