Description
Accurately calibrating RF cavities is challenging when the beam energy is not precisely known. This study presents a theoretical framework for low-energy accelerators to decouple beam energy from cavity amplitude by leveraging the derivative of the transit time factor (( T_s )). The approach involves performing a phase scan and measuring the time of flight between two BPMs. By analyzing the corresponding beam phases against each other, an ellipse is formed, whose semi-minor axis depends on the cavity amplitude (( V_0 )) and the beam energy. The rate of change of the ellipse's semi-axes with respect to ( V_0 ) varies for different beam energies due to the derivative of the transit time factor, enabling the disentanglement of beam energy from cavity amplitude.
