N2 - In the development of accelerator driven systems, ADS, free surface lead–bismuth spallation targets are
considered as promising solutions due to their possibility for compactness, their lifetime, and their ability
to transport the heat deposited by the proton beam away from the spallation zone. Experiments to characterise
the hydraulics of the targets are needed to allow the validation of numerical models and to
improve the design. Such experiments have been performed in water on a new concept labelled
"detached flow" geometry.The experiments show that a very stable main free surface with a small recirculation is obtained using
this geometry thanks to the presence of the second free surface and the nozzle geometry. The experiments
confirm that the level of the second free surface has no influence on the characteristics of the main
free surface, improving the main free surface control. The influences of the mass flow rate and of the inlet
velocity are evaluated.
