Observations of the Development of Striations in Large Barium Ion Clouds

Abstract

Striations develop within large (12-352 kg releases) barium ion clouds in a two-stage process. First the clouds split into sheets commencing at the trailing edge of the cloud. Then distortions or pinching effects within the individual sheets cause the formation of field-aligned raylike structures. In the clouds observed, the individual sheets were 200 m to 1000 m in thickness and were spaced 700 m to 2000 m apart. Quasi-sinusoidal waviness or spatially periodic thickenings exhibited a wavelength typically 700 m to 1000 m. When rod-like structures appeared, these were typically 200 m to 400 m in diameter and were spaced along the pre-existing sheet at 700 m to 1000 m on centers.
