The extreme ultraviolet is traced from Schumann’s beginning to the present day. Developments and progress since 1941 are discussed in detail. Progress in the spectroscopy of the sun and the stars from rockets and satellites, in high-temperature plasma spectroscopy and in techniques is also discussed, and attention is called to the close interrelations between these fields. 
An extreme ultraviolet radiation source for the simulation of the ionosphere
An extreme ultraviolet (EUV) radiation source for space simulation of plasma and other related phenomena in the laboratory has been developed. A total of forty‐eight small EUV lamps are put together
Wavelength measurements in the vacuum ultra-violet
Techniques of spectroscopic observations in the range from 2000 A to 10 A are reviewed with emphasis on precise wavelength measurements. The topics discussed include the design of spectrographs for
The synchrotron radiation of the 6-GeV DESY machine as a fundamental radiometric standard.
TLDR
The characteristics of synchrotron radiation emitted by the 6-GeV DESY machine were studied in the spectral range 2200-5500 A and good agreement was found between the experimental results and the values predicted by the theory of the synch Rotron radiation derived by J. Schwinger.
The spectroscopy of highly ionised atoms
Spectroscopic investigations of the structure of highly ionised atoms have undergone significant developments in recent years. The experimental progress is largely due to the introduction of several
Review of short wavelength laser research
TLDR
A review of the status of research towards achieving lasing action in the vacuum ultraviolet and soft X-ray spectral regions is presented and various possible methods of verifying the presence of gain with their relative merits are discussed.
Precision Laser spectroscopy in the Extreme Ultraviolet
Techniques for the production of short wavelengths in the extreme ultraviolet wavelength range are described, spanning low-order harmonic generation in the perturbative regime for narrow bandwidth
Use of a sliding spark in the vacuum ultraviolet range of the spectrum
A newly designed sliding spark source is described. The source has a broad spectral range whose lower end overlaps the X-ray range below 200 Å. It permits both photographic and photoelectric
