| Outline of Final Research Achievements |
By remodeling the forward detector of the electron spectrometer in the SCRIT electron scattering facility, it became possible to reconstruct the scattered electron trajectory three-dimensionally. Moreover, by using the three-dimensional drive type three-dimensional magnetic field measuring device manufactured in this research project, a magnetic field map in the spectrometer magnet was created and the momentum resolution of the spectrometer was improved. Furthermore, the performance of the spectrometer was evaluated from the width of the elastic scattering peak found in the momentum spectrum of the scattered electrons by using the newly manufactured carbon thin film target. In particular, we succeeded in separating and observing the peak of the first excited state (4.4 MeV) of carbon next to the elastic scattering peak. This is completely ready for the experiment with the coming unstable nuclear target.
