Description
The peak detected Schottky system is a powerful diagnostic tool for determining longitudinal beam parameters. According to the theoretical model, the peak value of the signal from a wideband pick-up contains information on particle distribution as a function of the synchrotron frequency. Due to intrinsic assumptions for modelling the acquisition set-up and uncertainties of beam parameters, a one-to-one comparison of predictions and measurements remains a challenge. This work presents the peak detected Schottky spectra obtained in idealized macro-particle simulations. Following refinement of the theoretical model, a direct comparison was performed under controlled conditions. Agreement with the numerical results was improved by introducing a form factor, which describes the probability of a particle being present in the observation window. Modifications due to collective effects are discussed as well. Finally, the corresponding peak detected spectra for various intensities, assuming a simplified impedance model, are presented.
