Striking pictures showing filamentary structures in plasma focus have intrigued researchers from the early days of research. A definitive understanding their occurrence, origin, structure and role physics is still not sight as summarized a recent comprehensive review. This because they are often observed "standard mode" operation with pure deuterium, particularly large installations, but found ...

The interaction of a dense plasma with short laser pulses (ns) is investigated. The dense plasma is created using a low-current hollow-cathode-triggered discharge. This configuration generates a dense plasma with an electron density of ne 10 17 cm 3 . Spectra are taken in the extreme ultraviolet (EUV) spectral range from11-18 nm to estimate the temperature. The interaction between plasma and la...

The expansion of a dense (initially, n(lpp)/n(0)>>1) laser-produced plasma into an ambient magnetized plasma ( n(0) = 2 x 10(12) cm(-3)) capable of supporting Alfvén waves has been studied. The interaction results in the production of shear Alfvén waves as well as large density perturbations (Delta n/n(0) approximately 0.3) associated with the moving dense plasma. The waves propagate away from ...

This paper proposes a novel and effective method for generating GigaGauss level, solenoidal quasi-static magnetic fields in under-dense plasma using screw-shaped high intensity laser pulses. This method produces large solenoidal fields that move with the driving laser pulse and are collinear with the accelerated electrons. This is in contrast with already known techniques which rely on interact...
