Abstract

In 1979 Tajima and Dawson, Tajima & Dawson (1979), on the basis of theoretical work and simulations, have shown that relativistic plasma waves are suitable for the development of

compact accelerators. In the proposed schemes, electrons were injected externally and were

accelerated through the very high electric field (GV/m) sustained by relativistic plasma waves

driven by lasers, in the laser beatwave regime or in the laser wakefield regime. Several

experiments have been performed following their idea and injected electrons at the few

MeV level have indeed been accelerated by electric fields in the GV/m range in a plasma

medium using the beat wave and laser wakefield schemes. With the development of more

powerful lasers, much higher electric fields were achieved, from few GV/m to more than 1

TV/m, Malka et al. (2002).

Abstract

Experimental and theoretical studies of Stark broadening of spectral lines in plasmas are the cornerstone of a large number of spectroscopic diagnostics of laboratory and astrophysical plasmas. As such, they are very important both fundamentally and practically, the latter being due to the numerous practical applications of plasmas. Examples are studies dealing with: controlled thermonuclear fusion (that would provide a virtually unlimited source of energy), plasma-based lasers for medical and other purposes, technological microwave discharges (especially those used for manufacturing microchips), a better understanding of solar activity, other astrophysical objects (white dwarfs, flare stars, and so on). The book reviews advances in this area achieved in recent years and presents new original papers building on these advances.
