Precisely phase-controlled laser pulse is considered essential for quantum control of matters, which is the basis of quantum information technology. In this study, we focus on the fact that the phase structure of electromagnetic waves emitted by high-energy free electrons reflects the motion of electrons. We have demonstrated that the time structure of radiated wave packets from undulators can be controlled with high accuracy in the range from femtoseconds to attoseconds. We have also succeeded in applying such undulator radiation to the observation of femtosecond-order ultrafast relaxation phenomena.

We have explored possibility of practical implementation of a very-short-period undulator in a compact electron storage ring. After intensive investigation for the storage ring of Aichi Synchrotron Radiation Center (Aichi SR), we confirmed that a feasibility study of such a undulator at the Aichi SR can be fulfilled. Conversion of the undulator to be installed in Aichi SR was performed successfully.
However, under the influence of COVID19, we finally concluded that the installation of the undulator and the feasibility study at the Aichi SR were not able to perform in time until the end of research period. We have converted our research plan and installed the undulator in the Accelerator Test Facility of KEK as a second best candidate for the present research at the final phase of FY2023 and prepared the feasibility study.
