Directed inward beams of ions in laser produced plasma
We investigated the ion characteristics in picosecond laser plasma
at laser radiation intensity of up to W/cm.
Our experimental observations of X-ray spectral line profiles
confirmed the presence of a great quantity of high-energy ions
(1 MeV) in laser plasma. Besides, by the
Doppler profile's red shift we revealed the high-energy ion motion
directed inward the target. For this phenomenon we suggest our
theoretical model. The high energy “tail” in the energy spectrum
of ions in laser plasmas can be explained by the pinch effect. The
effective way for production of beams of charged particles in laser
plasmas is the electric drift of these particles in electromagnetic
fields generated in the laser-produced plasmas

Composition, density and structure dependent neutron yields from deuterated targets in high-intensity laser shot
Experimental studies are presented on composition, density and
structure influence onto the neutron yield resulting from
deuterium-containing target interaction with laser light of
10 W/cm. Experimental data are compared with
theoretical and simulation results
