This dataset contains data which are used for generating Fig.2 to Fig.3 and Fig.5 to Fig. 15. These figures are plotted using MATLAB. The data contains x and y data for line graphs and mesh data for simulated surface plots.
The majority of the surface plots use triangular mesh data, with the exception of experimental data figures. This is obvious from the variable names used in the datasets.
The figures can be generated using the built-in MATLAB functions "plot" for line graphs and "trisurf" or "surf" for surface plots.
The figures are as follows:
Fig. 2 PDIV and PDEV (RMS values) for the 20 PD samples. All experiments were performed with a 50~Hz HV supply.
Fig. 3 PRPD patterns of four different samples with a 50~Hz HV supply at PDIV: (a) Sample 2, (b) Sample 6 (c) Sample 8 and (d) Sample 11.
Fig. 5 Comparison of photoionisation rate calculated using full model of photoionisation and Helmholtz model with modified boundary conditions. The Gaussian collisional ionisation production rate was centred at the origin:
(a) photoionisation rates along the z-axis and (b) photoionisation rates along the r-axis.
Fig. 6 Surface plot of numerical mesh element size.
Fig. 7 Discharge dependent variables for inception conditions at 0.4 ns: (a) electron number density, (b) positive ion number density, (c) electric field magnitude.
Fig. 8 Discharge dependent variables for inception conditions at 20 ns: (a) electron number density, (b) positive ion number density, (c) electric field magnitude.
Fig. 9 Discharge dependent variables for inception conditions at 10 mus: (a) electron number density, (b) positive ion number density, (c) electric field magnitude.
Fig. 10 Surface charge density on the void surface for inception conditions at different times during the discharge: (a) top surface and (b) bottom surface.
Fig. 11 Surface charge density on the void surface after the discharge had finished at different applied voltages magnitudes
Fig. 12 Relationship between the electric field before PD and the electric field after PD.
Fig. 13 Relationship between the electric field before PD and the apparent charge of the PD.
Fig. 14 A scatter plot of PD statistical quantities from experimental samples and the PD activity model for different values of c_e.
Fig. 15 Simulated PRPD pattern for c_e=8. The 50 Hz AC applied voltage RMS is set to the mean experimental PDIV value of 1.49 kV.
