To deepen the understanding of the plasma-catalyst interaction, it is crucial to study\u003Cbr \/\u003E\n the transport dynamics of charged species to the catalytic surface, which, due to collisions with\u003Cbr \/\u003E\n neutrals, also directly affects the transport of reactive species to the catalyst. Thereby the\u003Cbr \/\u003E\n transport of the charged species is in particular influenced by the electric field perpendicular to\u003Cbr \/\u003E\n the catalytic surface. However, experimental data on the component-wise electric field strength\u003Cbr \/\u003E\n within SDBDs are rare. To address this issue, we performed polarized optical emission\u003Cbr \/\u003E\n spectroscopy on the shifting and splitting of the allowed 492.19nm and forbidden\u003Cbr \/\u003E\n 492.06nm helium line pair. This diagnostic approach requires a non-radially\u003Cbr \/\u003E\n symmetric geometry, which leads to an adapted reactor design of the MCPA allowing the\u003Cbr \/\u003E\n side-on observation of the discharge. The discharge operates in pure helium at atmospheric\u003Cbr \/\u003E\n pressure, utilizing a triangular excitation voltage with a frequency of 15kHz and an amplitude\u003Cbr \/\u003E\n of 600V. We performed phase-resolved measurements of the electric field components with a\u003Cbr \/\u003E\n temporal resolution of 1\u00b5s. Our results revealed an electric field strength of approximately\u003Cbr \/\u003E\n 22kV\/cm for the component perpendicular to the dielectric surface, while the component\u003Cbr \/\u003E\n parallel to the dielectric surface is about 5kV\/cm larger during the decreasing potential phase\u003Cbr \/\u003E\n of the applied voltage.\u003C\/p\u003E\n","url":"https:\/\/rdpcidat.rub.de\/dataset\/electric-field-components-within-micro-scaled-dbd-measured-stark-shifting-and-splitting","state":"Active","log_message":"Edited by kd.","private":true,"revision_timestamp":"Thu, 11\/28\/2024 - 15:24","metadata_created":"Tue, 09\/24\/2024 - 15:56","metadata_modified":"Thu, 11\/28\/2024 - 15:24","creator_user_id":"6c1e1ea8-664d-46f3-9669-db1ec7d49113","type":"Dataset","resources":[{"id":"6716aa2a-9ca4-43d4-a2af-bbe6da0ae29e","revision_id":"","url":"https:\/\/rdpcidat.rub.de\/sites\/default\/files\/fig1_data.txt","description":"\u003Cp\u003EThe plotted shifts of the allowed and forbidden sub-transitions calculated by J.
