Abstract

Turbulent interactions between Alfvén waves are a common occurrence in astrophysical plasma environments. Many experiments have been conducted to understand these interactions. In this paper, we describe an experiment for the collision of two counterpropagating Alfvén waves. The magnetic and electric field data from the collision is used to determine the energy density and the energy flux density (or Poynting vector) for the waves. Additionally, we discuss some interesting results from a measurement of the Alfvén speed when at least one of the Alfvén waves in the experiment has multiple, nonzero k values.
