# Estimating chromatic properties of electron beams from frequency analysis of turn-by-turn beam position data

@article{Zisopoulos2020EstimatingCP, title={Estimating chromatic properties of electron beams from frequency analysis of turn-by-turn beam position data}, author={Panagiotis Zisopoulos and Y. Papaphilippou}, journal={arXiv: Accelerator Physics}, year={2020} }

A method to estimate linear chromaticity, RMS energy spread, and chromatic beta-beating, directly from turn-by-turn beam position data in a circular electron accelerator, is presented. This technique is based on frequency analysis of a transversely excited beam, in the presence of finite chromaticity. Due to the turn-by-turn chromatic modulation of the beam's envelope, betatron sidebands appear around the main frequency of the Fourier spectra. By determining the amplitude of both sidebands…
