| Outline of Final Research Achievements |
In this project, we have developed a breakthrough instrument for soft X-ray spectroscopies under an ambient environment and low-vacuum condition. Concurrently with the development, practical-oriented types of magnetic thin films and nanostructures have been fabricated and investigated, whose structures are promising candidates for novel devices. The final goal of the project is to achieve operando spectroscopies in an ambient environment for the device-related magnetic nanostructures at a soft X-ray synchrotron beamline. Firstly, we established methodology to introduce soft X-ray beams into low-vacuum or atmospheric pressure environment from a ultra-high vacuum chamber of the beamline. Consecutively, we designed and manufactured a prototype of reflectometer for a measurement of soft X-ray resonant reflectivity, based on a preliminary optical simulation to realize the spectroscopic measurements by means of photon detection method in a low-vacuum chamber at the end of beamline.
