  The results of experimental investigations of the ejection of electrons from
gas-discharge nonneutral electron plasma at interaction of vortex structures
have been given. The periodical approach of vortex structures causes the
ejection of electrons both from the vortex structures themselves and from the
adjacent regions of electron sheath to the end cathodes of discharge device.
The ejection takes place in the form of short and long pulses following each
other. The nature of these pulses and the dynamics of interaction of vortex
structures at their approach were studied.
