The Research Trail of the X-ray
Radiology, 1934The x-ray in the public mind is associated chiefly with hospitals, physicians' offices, and dental chairs. It is well known to have brought about revolutionary changes in the diagnosis and treatment of disease, and to have a place in the investigations and teaching of physics, but fewer know that the trail of research, which led down the centuries to ...

X-ray microbeam for speech research
Nuclear Instruments and Methods in Physics Research, 1982Abstract A steerable X-ray beam system is being built for use in speech research. A beam of 150 keV to 600 keV electrons will be steered by a computer and the resulting X-rays will be selected by a pinhole to give a beam with a width of 0.6 mm. The X-ray beam will be used to follow about 8 gold pellets on tongue and throat surfaces at sampling ...

LEOS 2001. 14th Annual Meeting of the IEEE Lasers and Electro-Optics Society (Cat. No.01CH37242), 2002
A 1 mm thick silver slab target was irradiated by one beam line of our chirped pulse amplification (CPA) Nd:glass laser system. The x-ray laser output from the nickel-like silver plasma was observed by use of a grazing incidence spectrometer. In this spectrometer, we used a laminar type grating and the detector was a back-illuminated charged couple ...

X-Ray Diffraction in Mineralogical Research
Journal of ISAS, 2023A brief account of role of X-ray diffraction (XRD) in mineralogical research with special reference to radioactive and atomic minerals is given. Aspects of research methodology such as sample preparation, analysis time, limitations, search match methods for identification, and complimentary techniques are also given. The most common applications of XRD

Capillary X-ray laser research
The fourth international conference on dense z-pinches, 1997A table-top capillary discharge soft X-ray laser system has recently been developed at Imperial College in order to evaluate its potential as a back-lighting source for solid density hydrogen plasmas. 1-D MHD simulations incorporating non-LTE ionization dynamics indicate the generation of the neon-like ionization stage of argon just prior to stagnation

Progress in X-ray laser research
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1987The first international meeting allowing a session devoted to the X-ray laser investigations took place in Atlanta (Georgia, U.S.A) five years ago(1), In this meeting, the dense plasmas produced by laser impact were emphasized as the possible active medium for an X-ray laser. For our group it reported experimental results on the soft X-ray emission and
