Abstract:A strong quasi-stationary magnetic field is generated in hollow targets with curved internal surface under the action of a relativistically intense picosecond laser pulse. Experimental data evidence formation of quasistationary strongly magnetized plasma structures decaying on the hundred picoseconds time scale, with the maximum value of magnetic field strength of the kilotesla scale. Numerical simulations unravel the importance of transient processes during the magnetic field generation, and suggest the exist… Show more
