Abstract

The characteristic of the electrostatic mode excited in non-neutral plasma in the equilibrium state is closely related to the internal state of plasma. This relationship has been used for non-destructive diagnosis of non-neutral plasma. Under the present conditions, this diagnosis is only supported by simplified theory. We employ numerical simulation reflecting actual experimental conditions and examine the characteristic of this electrostatic mode.
