A compact high-resolution spectrometer based on a segmented conical crystal analyzer
(American Institute of Physics, 2020-04)
In this work, the design, fabrication, and evaluation of a compact, one-shot spectrometer based on a segmented conically bent crystal analyzer are described. The system is a “one-shot” wavelength dispersive spectrometer, ...
Incoherent scattering by free electrons as a technique for studying the ionosphere and exosphere: observations and theoretical considerations
(National Institute of Standards and Technology, 1959-09-18)
Incoherent scattering by the free electrons of the ionosphere has been predicted and offered as a technique for measuring the electron density profile both below and above the F region maximum. This paper reports observations ...
