The electron swarm parameters (bulk drift velocity, bulk longitudinal component of the diffusion tensor, and effective ionization frequency) in C2H2 (acetylene) are investigated for a wide range of the reduced electric field by means of measurements and kinetic calculations. The dataset contains results of measurements in a scanning drift tube apparatus under time-of-flight conditions as well as of kinetic swarm calculations, using solutions of the electron Boltzmann equation and Monte Carlo simulations.

The dataset includes all the input and output files for the paper: Comparison of six simulation codes for positive streamers in air (https://doi.org/10.1088/1361-6595/aad768). Three test cases for axisymmetric positive streamers are described in the paper. The codes are of the finite volume or the finite element type, and they use both explicit and implicit time stepping. The computational domain and initial conditions are kept simple, so other codes can be compared relatively easily to the data published here.
