Plasma fusion diagnostics with fast lithium beams
Lithium beam diagnostic systems have been installed at the magnetic fusion experiments ASDEX Upgrade (AUG) and WENDELSTEIN 7 AS (W7 AS) of IPP Garching, Germany. A lithium atom beam injector has been improved, now delivering about 1.1 mA of equivalent neutral particle current at a beam energy of 35 keV. By means of lithium induced impact excitation spectroscopy (Li-IXS), electron density profiles have been measured in the scrape off layer of AUG and throughout the full radial range for W7 AS low density plasmas. In addition, at W7 AS the neutral particle density outside the plasma could be measured with high temporal resolution. Set-ups for impurity ion density measurements (lithium charge exchange spectroscopy) have been installed on both experiments.
