Outline of Final Research Achievements

The extreme ultraviolet region where a lot of emission lines of ion and atoms gather is important in observing space plasmas. To avoid absorption by the earth's atmosphere, the observation from space is needed. At this wavelength, it is compact and lightweight, and equipment that realizes highly efficient observation is necessary. Through this study, we have established a method to realize detection efficiency better than 2 to 10 times higher than the conventional ones. We also proposed an optimal storage method to maintain its sensitivity. As a result, we were able to establish a path to realize observation with much higher efficiency at lower cost than before.
