We consider current instabilities of Alfven waves in the Earth’s magnetosphere tail, which are caused by proton beams propagating in the plasma sheet boundary layer. The increment is found and instability growth rate is estimated. It is shown that such generation mechanism of Alfven waves is very effective and can lead to the wave generation even at very small currents
