Abstract
ToThe stability of high-speed liquid lithium film flows on a wall was analytically studied for the neutron source in Boron Neutron Capture Therapy (BNCT), which makes cancers and tumors curable with cell-level selections and hence high QOL. The object of our research is to materialize the thin and high-speed wall film flows of liquid lithium in a high-vacuum as an accelerator target. Linear analysis approach is made to the stability on thin film flows of liquid lithium in a high-vacuum. We experimentally observed the splitting phenomena of film flows on a wall with 0.5 mm in film thickness and over 10.0 m/s in flow velocity, caused by the slit-nozzle was stopped up with the contaminant particulate of nitrous lithium. We also obtained the knowledge to materialize the desired wall film flows.
