Extreme Ultraviolet: the Grand Adventure
Charles Clark
Fellow and Co-Director, Joint Quantum Institute, NIST; and

This year marks the 100th anniversary of Niels Bohr's theory of the atom, a breakthrough contribution to modern understanding of the microscopic structure of matter. One of the early predictive successes of Bohr's model occurred in early 1914, when hydrogen emission lines in the extreme ultraviolet (EUV) region of the spectrum were discovered by Theodore Lyman at precisely the wavelengths predicted by Bohr's theory. The EUV region is one of the most difficult domains of the electromagnetic spectrum in which to conduct accurate measurement, and its exploration began little more than a century ago. Yet the EUV contains a vast quantity of information about the universe that cannot be found elsewhere, and it is a subject of increasing importance in applications on earth. I will give an overview of the grand EUV adventure.
