On the Cover

Images of part of a cycle of "hollow" electron beam evolution in the Duke storage ring; the beam consists of a large outside ring and a small core beam. Initially there is a phase of slow migration from ring to core (images 1-5), followed by a rapid core burst when the charge in the core becomes unstable (6-8), after which the beam quickly returns to the initial configuration to start the cycle again.
