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.

The plasma parameters of a large-area dielectric barrier discharge (DBD) in argon-HMDSO mixtures containing up to about 1600 ppm of the monomer are investigated by means of numerical modelling. A time-dependent,
spatially one-dimensional fluid model is applied, taking into account the spatial variation of the discharge plasma between plane-parallel dielectrics covering the electrodes. The dataset contains values of power dissipated in the DBD as well as the space- and period-averaged density and mean energy of the electrons as a function of HMDSO admixture.

The HelixJet (https://www.inptdat.de/helixjet) was applied to simultaneous melting and plasma treatment of polyamide (PA 12) microparticles (diameter 60 µm) used conventionally for 3D printing by laser sintering. This proof-of-principle experiment demonstrated that gaussian thickness profiles of PA 12 can be printed using the HelixJet with a rapid rate of 200 mg/s (peak growth 2 mm/s) and with advantageous material properties. The key element of this novel process is the self-regulated balance between material melting and plasma quenching.

The dataset contains data from comparative studies of capacitively coupled radio-frequency (CCRF) discharges in helium and argon at pressures between 10 and 80 Pa applying two different fluid modeling approaches as well as two independently developed particle-in-cell Monte Carlo collision (PIC-MCC) codes. The dataset provides a test bed for future studies of simple ccrf discharge configurations in helium and argon at pressures ranging from 10 to 80 Pa.

The self-organized behaviour (locked mode) of filaments in the non-thermal atmospheric pressure plasma jet (ntAPPJ) couples a spatial patterning of the discharge (helical symmetry) and a regular motion (steady rotation). The dataset represents the mean rotation frequency of filaments in the capillary with a diameter of 4 mm and the corresponding geometric characteristics: helicality and/or filament inclination angles were measured along with the gas temperature under varying discharge conditions (electric power and argon flow rate).

The dataset is the raw data (presented in numerical format) from the EPR, 1H NMR and HR-MS experiments. The respective Excel files describe the experiments to which the dataset belongs. Please refer to the original publication and ESI for more information.
