Abstract The Schottky monitors of the Large Hadron Collider (LHC) can be used for non-invasive beam diagnostics to estimate various bunch characteristics, such as tune, chromaticity, profile or synchrotron frequency distribution. However, collective effects, in particular beam-coupling impedance, significantly affect spectra when large charges are involved. In conditions, available interpretation methods difficult apply directly measured spectra, thus preventing extraction and machine...
The observation of transverse Schottky spectra provides insight into intrabunch particle dynamics and serves in numerous facilities to derive important beam machine parameters, such as the betatron tune, first-order chromaticity, emittance. original theory confirming validity these observations has been, however, developed by taking strong assumptions on motion both longitudinal planes. In this work, we loosen assumptions, proving that relationships linking with emittance tune remain...
