Description
We describe the first measurements of plasma formation by a 20thinspthinspnsec, 9thinspthinspMeV, 20 kA/cm2 Li+3 ion beam injected into 2-Torr argon, conditions similar to inertial-fusion ion-beam transport requirements. A new visible-spectroscopy diagnostic exploits ion-beam-excited Ar II transitions to measure the time-resolved plasma electron density (1015 cm-3 endash 1016 cm-3) and temperature (1 endash 2thinspthinspeV) during the initial breakdown phase. Stark broadening and line intensity ratios are used as diagnostics after the plasma forms. Comparisons with computer simulations examine intense-beam effects important for the transport of light- and heavy-ion beams. copyright 1999 The American Physical Society
