A novel Lagrangian integral formalism is applied to pure electron
diodes.
Analytical expressions are obtained in terms of the injected current and
of
the potential
drop for two DC states. These two states are either completely transmitted
flows
or flows with partial reflection at a virtual cathode. Splitting rates
and other
quantities are presented for arbitrary potentials.

The stability of Pierce-like plasma diodes is investigated for arbitrary ion injection velocities. A recently developed integral formalism that accounts for ion dynamical effects is applied to derive a generalized dispersion relation for electrostatic perturbations. Its evaluation exhibits several new features, such as the appearance of growing oscillatory modes, which become Pierce–Buneman modes in the limit of initially resting ions, and of weakly damped oscillatory modes, which become undamped ion plasma oscillations in this limit. The stability of this bounded plasma system is shown to be controlled by the new control parameter α̂=α(1+μ̂)1/2, where α is the Pierce parameter and μ̂≡mev2e0/miv2i0 the ratio of electron and ion kinetic energy at the emitter.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
