UNSTABLE PERIODIC SPATIOTEMPORAL STATES IN DISTRIBUTED ACTIVE SYSTEM WITH SUPERCRITICAL CURRENT

摘要

We study a set of unstable periodic spatiotemporal states characterizing the chaotic spatiotemporal dynamics of the electron beam with supercritical current in the Pierce diode. The quantitative characteristics (maximum Lyapunov exponents) of the revealed unstable spatiotemporal states of the chaotic dynamics of a distributed self-oscillating system are calculated.
