A good\u0026amp;#xD;qualitative agreement between experiments and simulations is found. It is shown that by\u0026amp;#xD;applying microsecond or nanosecond driving voltage waveform pulses, the discharge exhibits\u0026amp;#xD;filamentary or homogeneous structures. The time evolution\/propagation of the homogeneous\u0026amp;#xD;surface ionization wave for different nitrogen admixtures, pressures, and applied voltage is\u0026amp;#xD;studied and analyzed. Both, simulations and experiments indicate that for the positive applied\u0026amp;#xD;voltage pulse, a streamer possessing the typical dynamics of the positive streamer is ignited\u0026amp;#xD;on the powered side of the electrode. At the same time, on the grounded sides, two streamers\u0026amp;#xD;are formed: one possessing the dynamics of a negative streamer, which propagates towards\u0026amp;#xD;the center of the cell of the electrode grid, and a positive one in the opposite direction. It\u0026amp;#xD;is also shown that the positive streamers on the powered side are partly responsible for the\u0026amp;#xD;velocity of the negative streamers on the grounded side as simulations show a deceleration of\u0026amp;#xD;the negative streamers as soon as two positive streamers collide and then close to the meeting\u0026amp;#xD;point vanish due to the repulsive electrostatic interactions between them. Additionally, from\u0026amp;#xD;the time-resolved measurements of the emission signal, the quenching rate constants of the He-I\u0026amp;#xD;(3s)3S1 state by collisions with helium and nitrogen are determined to be 9(\u00b14) \u00d7 10\u221212 cm3s\u22121\u0026amp;#xD;and 3(\u00b11) \u00d7 10\u221210 cm3s\u22121, respectively at T = 400 \u00b1 50 K.\u003C\/p\u003E\n","url":"https:\/\/rdpcidat.rub.de\/dataset\/streamer-propagation-dynamics-nanosecond-pulsed-surface-dielectric-barrier-discharge-hen2","state":"Active","log_message":"Edited by kd.","private":true,"revision_timestamp":"Wed, 11\/20\/2024 - 10:27","metadata_created":"Wed, 11\/13\/2024 - 11:03","metadata_modified":"Wed, 11\/20\/2024 - 10:27","creator_user_id":"2fa50069-3923-4774-ad70-7f98bd94212e","type":"Dataset","resources":[{"id":"efc03c42-9030-4194-828c-f39fb006556b","revision_id":"","url":"https:\/\/rdpcidat.rub.de\/sites\/default\/files\/Figure_Draft_Huebner2024.zip","description":"","format":"zip","state":"Active","revision_timestamp":"Thu, 11\/14\/2024 - 08:31","name":"Streamer propagation dynamics in a nanosecond pulsed surface dielectric barrier discharge in He\/N2 mixtures Data","mimetype":"application\/zip","size":"38.03 MB","created":"Wed, 11\/13\/2024 - 11:20","resource_group_id":"60dfa3fb-4113-4271-8531-8587fa07dcbe","last_modified":"Date changed  Thu, 11\/14\/2024 - 08:31"}],"tags":[{"id":"ec7dcc6e-8d82-4aa5-8f31-8ce85bd390b5","vocabulary_id":"2","name":"A5"},{"id":"6fb4f0e8-f239-47f1-9fef-1eb933f5195a","vocabulary_id":"2","name":"SDBD"},{"id":"2af5d325-26a2-40a8-b854-6a483281518e","vocabulary_id":"2","name":"PROES"},{"id":"7d26cd04-5f55-4d74-a9e9-87aacc8261a0","vocabulary_id":"2","name":"NONPDPSIM"}],"groups":[{"description":"\u003Cp\u003EThe group \u0022Allgemeine Elektrotechnik und Plasmatechnik\u0022 at the faculty for engineering and information science.\u003C\/p\u003E\n","id":"60dfa3fb-4113-4271-8531-8587fa07dcbe","image_display_url":"https:\/\/rdpcidat.rub.de\/sites\/default\/files\/AEPT2.png","title":"AEPT","name":"group\/aept"}]}]}
