Generation of pure, metal-vapor plasmas with peak densities above 10(19) cm
(-3) is reported. The plasma production is based on the explosive ablation
of electrode material in the capillary ms discharge. The plasma density is
controlled by varying the discharge parameters. High purity and density wer
e achieved by optimizing the electrode configuration, the capillary materia
l, and dimensions. (C) 1999 American Institute of Physics. [S0003-6951(99)0
