Abstract

Thermal lithium beams are used in physics for different purposes. To overcome certain disadvantages of conventional liquid-lithium ovens concerning handling, conditioning and lifetime of the Li filling, a solid Li-evaporation device was constructed. An aluminium-based alloy containing about 9 at.% of lithium was employed. The parameters of the beam (axial and radial flux profiles) were measured as a function of temperature and time. At a distance of 100 mm from the oven, Li flux densities of more than 2 x 1.0 E14 cm2 s were achieved, lasting for more than 16 days of continued operation. The full beam divergence at half maximum was 8 . As a typical application of the device in plasma diagnostics, radial electron density profiles were measured in the scrape-off layer of the TEXTOR tokamak.
