Times Cited Count:6 Percentile:41.12(Materials Science, Multidisciplinary)The IFMIF lithium target mock-ups have been constructed and tested at water and lithium test facilities. Jet velocity in both mock-ups was up to 20 m/s. Calculations and experiments showed instability of lithium flow at conjunction point of straight and concave sections of the mock-up back wall. Profile of water velocity across the mock-up width, jet thickness, and height of waves were measured. A significant increase of thickness of both water and lithium jets near the mock-up side walls was observed. The influence of shape of the nozzle outlet part on jet stability was investigated. Evaporation of lithium from the jet free surface was investigated as well as deposition of lithium on vacuum pipe walls of the target mock-up. It was showed that these phenomena are not so critical for the target efficiency. The possibility of removal of nitrogen in lithium down to 2ppm by means of aluminum getter was showed.
