Figure 6

Normalized spatio-temporal plots of the electron impact excitation rate from the ground state into He I 3S1 obtained experimentally (first row) and from PIC/MCC simulations, for different N_2 reactive gas admixtures. The positions of the sheath edges are shown as a solid white line (second row). The data are plotted for ‘peaks’-waveforms with N=4 and Vpp=400V. The third row shows EEPFs averaged over different spatio-temporal regions of interest marked in row 2. The black solid line corresponds to the EEPF averaged over the entire electrode gap and RF period of the fundamental driving frequency. The fourth row shows the time averaged helium metastable density profiles extracted from the PIC/MCC simulation. The powered electrode is located at x=0, while the grounded electrode is at x=1mm. The base frequency is f=13.56MHz.
