X-ray variability in transient X-ray sources
Il Nuovo Cimento C, 1990The X-ray variability of transient X-ray binaries is analyzed in terms of the orbital motion of the neutron star, centrifugal inhibition of accretion and of the variable moss loss rate due to activity of the optical counterpart. The systems A0535+26 and V0332+53 are studied in this respect.

A plasma x-ray source for x-ray lithography
Journal of Vacuum Science & Technology B: Microelectronics Processing and Phenomena, 1986Employing a gas-‘‘puff’’ z-pinch plasma, a high brightness and compact plasma x-ray source has been constructed by using a high-repetition-rate discharge and a new x-ray extraction method. The high-repetition-rate discharge (3 Hz) is attained by using a fast-acting gas valve, capable of operating stably under gas plenum pressures below 300 Torr.

Extragalactic X-ray Sources and the X-ray Background
Nature Physical Science, 1973ALTHOUGH the existence of the cosmic X-ray background has been known for the past ten years, the origin of this radiation has not been identified. Many theories have been proposed (see reviews by Silk1 and Setti and Rees2), but many of these have more parameters than the observations could define and much use has been made of the so-called “spectral ...

X-ray was the name given by W C Roentgen to the highly penetrating rays which emanated when high-energy lectrons struck a meta ltarget. On 8 November 1895, he noted for the first time this phenomenon and on 28 December 1895, he astonished the scientific world with his preliminary report "Ueber eine neue Artvon Strahlen" (along with experimental ...

In this chapter, standard stationary-anode, rotating anode and microfocus X-ray tubes are described and the spectra from these tubes are compared with the output from synchrotron-radiation sources. The choice of beam size, X-ray wavelength, spectral composition, intensity, cross fire and beam stability are discussed and a description is given of the ...

The study of the X-ray emission from M31 is a young field, having its beginnings in the mid-1970’s. By 1991, however, a fairly good understanding of the various sources is at hand. The importance of these sources is the result of the happy fact that M31 is a normal, high-luminosity galaxy; it therefore provides a good opportunity to study the X-ray ...

The development of more powerful sources plays a major role in the overall improvement of X-ray techniques in general and of topography in particular. In recent years some progress has been made to increase the brightness and also the total photon flux of conventional sealed-off X-ray tubes.

X-Ray Spectra of Galactic X-Ray Sources
1980With the exception of a few supernova remnants, we presently believe that all the X-ray sources in the galaxy with Lx ≳ L⊙ arise in binary systems, one member of which is a degenerate dwarf, a neutron star, or a black hole. The energy source for the X-radiation in such a system is the gravitational energy liberated when mass is transferred to the ...
