There is an increasing use of high energy photons in many fields of research and in industry. Where large installations such as synchrotrons or dedicated laser based source facilities can provide solutions for specific needs, they are presently unabl

We developed and studied three different extreme ultraviolet (EUV) capillary discharge sources either dedicated to the generation of coherent or incoherent EUV radiation. The CAPELLA source has been developed especially as an EUV source for the metro

This paper describes the development and application of a new x-ray based diagnostic technique. A compact flash x-ray source emitting 20 ns pulses of around 8 to 10 keV x-ray photons is used to induce the fluorescence of argon jets in ambient air. Th

This paper describes the development and application of a soft x-ray flash radiography technique. A very compact soft x-ray flash source has been specially designed for these studies. The table-top x-ray source developed in this work emits strong dos

An overview of the plasma based sources of energetic photons, ranging from UV to hard X‐rays, developed in GREMI is proposed. Each source principle is shortly described and applications of these specially designed sources are documented. The possib

A xenon filled capillary discharge has been developed for efficient EUV radiation production with emphasis on the wavelength range around 13.5 nm in view of application to EUV lithography. This source will be operated in a multi-watt, kHz and low deb

An argon plasma generated by a fast capillary discharge for the amplification of Ar IX 46.9 nm line has been studied experimentally by time‐resolved pinhole imaging and XUV spectroscopy. Self breakdown by hollow cathode effect induces plasma igniti

This work reports the optimization, in the far UV, of fast (pulses ≃5 μs) conventional flash lamps. At constant energy deposition, the best effeciency in the range 200-300 nm has been obtained in Xe-O 2 mixtwes with an increase of the order of 50%

In dense arc plasmas (T approximately=12500K, Ne approximately=1-6*1012 cm-3) the high continuum emission, the strong broadening and self-absorption of the lines, as well as more fundamental problems of non-ideality (ND=8/3 pi Ne lambda D3 not >>1) r
