After a brief introduction to the NIST EBIT facility, we present the results of three different types of experiments that have been carried out there recently: EUV and visible spectroscopy in support of the microelectronics industry, laboratory astro

Astrophysics with Xspect/Sodart on Spectrum X-Gamma
Autor: H. W. Schnopper
Publikováno v: Astrophysics and Space Science Library ISBN: 9789401043410
The XSPECT/SODART X-ray telescopes and their associated focal plane instrumentation will be launched on board the Russian X-ray mission SPECTRUM ROENTGEN-GAMMA in December 1995. Technical details of the mission and of the telescopes have been discuss

Autor: Allan Hornstrup, Chris Hall, Robert A. Lewis, Peter Grundsøe, C. Nilsson, P. Frederiksen, P. Ørup, Finn Erland Christensen, H. W. Schnopper, E. Jacobsen
Publikováno v: Christensen, F E, Hornstrup, A, Frederiksen, P, Nilsson, C, Grundsøe, P, Ørup, P, Jacobsen, E, Schnopper, H W, Lewis, R & Hall, C 1992, ' A beam expander facility for studying x-ray optics ', Review of Scientific Instruments, vol. 63, no. 1, pp. 1168-1171 . https://doi.org/10.1063/1.1143124
The detailed study of the performance of full scale x-ray optics often requires the illumination of large areas. This paper describes a beam expander facility at the Daresbury Synchrotron Radiation Facility. It combines monochromatization and beam ex

Model for radiative electron capture: an interpretation of the line width
Autor: K Kirby-Docken, A. R. Sohval, J. P. Delvaille, K. Kalata, H. W. Schnopper
Publikováno v: Journal of Physics B: Atomic and Molecular Physics. 9:L25-L29
Radiative electron capture (REC) X-ray profiles have been analysed for oxygen ions incident on a variety of gaseous targets. A model for REC is given which includes the effects of binding in both the target and projectile and the target electron mome

SPectral Observation of the Soft X-Ray Background and of the North Polar Spur with Solid State Spectrometers
Autor: R. Rocchia, M. Arnaud, C. Blondel, C. Cheron, J. C. Christy, L. Koch, R. Rothenflug, H. W. Schnopper, J. P. Delvaille
Publikováno v: Symposium - International Astronomical Union. 101:357-360
In this paper, we present preliminary results of soft X-ray diffuse background observations. We observed two particular regions of the sky in the 0.3–1.5 keV range. The detection system consisted of three independent, 1 cm diameter, cooled solid st

Cross section ratio for radiative electron capture to inner and outer atomic shells
Autor: A. R. Sohval, K. Kalata, H. W. Schnopper, J. P. Delvaille
Publikováno v: Journal of Physics B: Atomic and Molecular Physics. 9:L47-L51
X-ray spectra, in which radiative electron capture, both to the outer (n>or=2) shells and to the K shell of the projectile, is observed, have been collected for 30-65 MeV 16O ions incident upon various gas targets. The measured capture ratio is in re
