Abstract
A hollow, rotating 2.3-MeV electron beam, moving with axial velocity of ∼0.25c after injection through a magnetic-field cusp, is slowed down and trapped in a small magnetic mirror well by interaction with a 30-60-Ω/square resistive wall. The trapped-electron ring containing ∼ particles performs a damped oscillation about the well minimum and settles down into an equilibrium state.
