Title: Hydrogen and helium recycling from a JxB -force convected liquid metal Ga 67In 20.5Sn 12.5 under steady state plasma bombardment

A series of first-of-a-kind laboratory-scale experiments on the JxB-force convected liquid metal divertor concept have been carried out in the temperature range from room temperature to ~200 °C, employing a eutectic alloy: Ga 67In 20.5Sn 12.5, the melting point of which is 10.5 °C. The electrical current conducted through the alloy is set at about 70A and the magnetic field is set at about 700 G. Finally, it has reproducibly been observed that hydrogen as well as helium particle recycling is noticeably reduced under steady state plasma bombardment when the liquid is convected by the JxB force.
