This Letter reports the operation of a pulsed hollow-cathode discharge that creates high densities of excited-state lithium ions. This discharge operates at high current density (25 A/cm(2)) and high voltage (1000 V) and maybe useful for the realization of proposed schemes for XUV lasers and radiation sources based on storage in metastable levels.
