| Outline of Final Research Achievements |
In this research, we developed a method to calculate position information of superconducting acceleration cavity cooled to cryogenic temperature from higher harmonics induced by passing electron beam. Since the beam energy was low in the past experimental data using the actual beam, the cavity passing beam trajectory is complicatedly bent by the fringe field of the acceleration mode that was simultaneously present at that time. Starting from estimating such a complicated beam trajectory by calculation, the electrical center of the harmonic mode is known in advance by calculation, and the absolute value with the electrical center calculated by using the beam excited harmonic mode, we developed a method to calculate the cavity position by minimizing their deviations without contradiction.
