Abstract
The final beam transport in the reactor chamber for heavy ion
fusion in preformed plasma channels offers many attractive
advantages compared to other transport modes. In the past few
years, experiments at the Gesellschaft für
Schwerionenforschung (GSI) accelerator facility have addressed
the creation and investigation of discharge plasmas, designed
for the transport of intense ion beams. Stable, self-standing
channels of 50 cm length with currents up to 55 kA were initiated
in low-pressure ammonia gas by a CO2-laser pulse
along the channel axis before the discharge is triggered. The
channels were characterized by several plasma diagnostics including
interferometry and spectroscopy. We also present first experiments
on laser-guided intersecting discharges.
