Various methods for performing conditional analysis of plasma turbulence are discussed and compared. The study experimentally investigated low‑frequency electrostatic turbulence driven by the ion–ion beam instability in a double‑plasma device, recording real‑time signals and applying conditional statistical analysis. Conditionally averaged potential distributions show long‑lived structures that are interpreted as ion phase‑space vortices and clump formation in collisionless plasmas.
Low-frequency electrostatic turbulence generated by the ion–ion beam instability was investigated experimentally in a double-plasma device. Real time signals were recorded and examined by a conditional statistical analysis. Conditionally averaged potential distributions reveal the formation and propagation of structures with a relatively long lifetime. Various methods for making a conditional analysis are discussed and compared. The results are discussed with reference to ion phase space vortices and clump formation in collisionless plasmas.
