Laser-Plasma Interaction Experiment for Solar Burst Studies

Alternating-code experiment for plasma-line studies

We present results of the first plasma-line measurement of the incoherent spectrum using the alternating-code technique with the EISCAT VHF radar. This technique, which has earlier mostly been used to measure high-resolution E-region ion-line spectra, turned out to be a very good alternative to other techniques for plasmaline measurements. The experiment provides simultaneous measurement of the...

Mathematical Models for Laser-plasma Interaction

We address here mathematical models related to the Laser-Plasma Interaction. After a simplified introduction to the physical background concerning the modelling of the laser propagation and its interaction with a plasma, we recall some classical results about the geometrical optics in plasmas. Then we deal with the well known paraxial approximation of the solution of the Maxwell equation; we st...

Laser-produced plasma-wall interaction

Jets of laser–generated plasma represent a flexible and well-defined model environment for investigation of plasma interactions with solid surfaces (walls). The pilot experiments carried out on the iodine laser system (5–200 J, 0.44 mm, 0.25–0.3 ns, ,1 10 W/cm) at the PALS Research Centre in Prague are reported. Modification of macroscopic characteristics of the Al plasma jets produced at laser...

Electromagnetically confined plasma target for interaction studies with intense laser fields

The paper describes a novel application of an electron beam ion trap as a plasma target facility for intense laser–plasma interaction studies. The low density plasma target ( 10/cm) is confined in a mobile cryogenic electromagnetic charged particle trap, with the magnetic confinement field of 1–3 T maintained by a superconducting magnet. Ion plasmas for a large variety of ion species and charge...
