摘要: As many as eight multiple plasma bullets produced at atmospheric pressure were observed in one voltage period a capillary helium dielectric barrier jet. We found that the number of strongly depends on nitrogen fraction added to supply gas. Using optical emission spectroscopy and ionization rate calculation, this study demonstrates gas plays an important role generation dynamics through Penning by metastables.
