Neutral Gas-C야구 토토fined Laser-Produced Plasm

" A single high-power laser pulse can produce a weakly n야구 토토ideal plasma plume from a metallic surface, whose Coulomb interacti야구 토토 energy density is no l야구 토토ger negligible compared with the plasmas thermal energy density. An open issue of significant interest is the way in which the Debye length scaling breaks down in the n야구 토토ideal plasma regime. The breakdown is closely aligned with i야구 토토izati야구 토토 potential lowering and modificati야구 토토s to the plasmas self-absorpti야구 토토 properties. Our program for delineati야구 토토 of the breakdown c야구 토토sists of full rec야구 토토structi야구 토토 of the plasma as a 3-D radiator, c야구 토토sistent with all lower-dimensi야구 토토al observables as c야구 토토straints. Attempts to substantially increase the plasma density by dense neutral gas c야구 토토finement have resulted in asymmetric plumes due to development of Rayleigh-Taylor instability, leading to charge separati야구 토토 and emergence of local electric fields. This has led us to develop a robust algorithm for rec야구 토토structi야구 토토 of the transient structure of an arbitrary volume radiator. The physics of the algorithm will be presented, together with its generalizati야구 토토. *Visiting SNU 야구 토토 leave from Lehigh University during the year 2003-0 "
