AbstractIn this work we report on the characterization of pulsed soft x‐rays emitted from laser‐produced plasma. The plasma was generated by a pulsed KrF excimer laser focused on pure Si, Cu and Ta targets by 40, 80 and 120 mJ laser energies. The utilized detector was a very sensitive Faraday cup which opportunely biased was able to record time ...

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.

Radiation Sources: X-Ray Sources
2016X-ray was the name given by W. C. Roentgen (Figure 1(a)) to the highly penetrating rays which emanated when high energy electrons struck a metal target. On November 8, 1895 he noted for the first time this phenomena and on December 28, 1895 Roentgen astonished the scientific world with his preliminary report 'Ueber eine neue Art von Strahlen' given to ...

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.

In Chapter 1 you learned how crystals of a protein can be grown and you observed a diffraction pattern. The crystalline form of a protein is required to determine the protein’s structure by X-ray diffraction, but equally necessary are the tools for recording the diffraction pattern. These will be described in this chapter on hardware. The various X-ray

1987The authors have made a new deep 6 cm survey with the VLA in order to extend the radio source count to a lower flux density and to decrease the limits on the small scale fluctuations in the microwave background. The survey region covers ~10-5ster and is nearly coincident with the survey previously reported by Fomalont et al. (1984).
