This diagnostic uses the emission of the atomic states O(3p3P (\u03bb=844.6 nm), Ar(2p1) (\u03bb=750.4 nm) and He(33S) (\u03bb=706.5 nm) and allows the atomic oxygen density and the mean electron energy to be determined simultaneously from the spectral line intensity ratios. Here, the atomic states are selected in a way that they cover a wide range of the electron energy distribution function (EEDF). The method is compared to classical actinometry and energy resolved actinometry (ERA) based on measurements on the COST microplasma jet. In addition, a benchmark against two-photon absorption laser induced fluorescence (TALIF) measurements is performed. Both atomic oxygen densities and mean electron energies are in good agreement with the literature. Furthermore, SEA offers a number of advantages over known approaches. Firstly, the experimental complexity is significantly reduced by using time-integrated spectra instead of phase-resolved measurements, as used in the original ERA approach. Secondly, the resolution of the energy measurement can be\u003Cbr \/\u003E\nsignificantly improved by the use of the helium state. In addition, known uncertainties e.g. due to excitation of oxygen excited levels via metastable oxygen states can be reduced.\u003C\/p\u003E\n","url":"https:\/\/rdpcidat.rub.de\/dataset\/state-enhanced-actinometry-cost-microplasma-jet","state":"Active","log_message":"Edited by kd.","private":true,"revision_timestamp":"Sat, 03\/25\/2023 - 19:43","metadata_created":"Mon, 09\/19\/2022 - 14:40","metadata_modified":"Sat, 03\/25\/2023 - 19:43","creator_user_id":"91284078-6b39-44ab-8d2e-b3961249cf70","type":"Dataset","resources":[{"id":"b6adc6fe-094d-499a-8c8b-98fb32f4978d","revision_id":"","url":"https:\/\/rdpcidat.rub.de\/sites\/default\/files\/fig1_777_750.txt","description":"\u003Cp\u003EContour plot of the intensity ratio 777\/750 (fig.1)\u003C\/p\u003E\n","format":"txt","state":"Active","revision_timestamp":"Sun, 09\/25\/2022 - 11:55","name":"fig1 777_750","mimetype":"text\/plain","size":"7.98 MB","created":"Mon, 09\/19\/2022 - 14:49","resource_group_id":"ee65a14f-0fc2-40e9-a4ba-e85030fe5102","last_modified":"Date changed  Sun, 09\/25\/2022 - 11:55"},{"id":"d4c26c38-f3e5-45eb-a03c-463e6abb1e72","revision_id":"","url":"https:\/\/rdpcidat.rub.de\/sites\/default\/files\/fig1_706_750.txt","description":"\u003Cp\u003EContour plot of the intensity ratio 706\/750 (fig.1)\u003C\/p\u003E\n","format":"txt","state":"Active","revision_timestamp":"Sun, 09\/25\/2022 - 11:55","name":"fig1 706_750","mimetype":"text\/plain","size":"7.83 MB","created":"Mon, 09\/19\/2022 - 14:51","resource_group_id":"ee65a14f-0fc2-40e9-a4ba-e85030fe5102","last_modified":"Date changed  Sun, 09\/25\/2022 - 11:55"},{"id":"4e1992ec-d702-4429-84c3-6f3aec327a37","revision_id":"","url":"https:\/\/rdpcidat.rub.de\/sites\/default\/files\/fig1_844_750.txt","description":"\u003Cp\u003EContour plot of the intensity ratio 844\/750 (fig.1)\u003C\/p\u003E\n","format":"txt","state":"Active","revision_timestamp":"Sun, 09\/25\/2022 - 11:56","name":"fig1 844_750","mimetype":"text\/plain","size":"8.21 MB","created":"Mon, 09\/19\/2022 - 14:53","resource_group_id":"ee65a14f-0fc2-40e9-a4ba-e85030fe5102","last_modified":"Date changed  Sun, 09\/25\/2022 - 11:56"},{"id":"ebca6ac4-5ce0-4cff-9321-edcbb55fd634","revision_id":"","url":"https:\/\/rdpcidat.rub.de\/sites\/default\/files\/fig2_proes.txt","description":"\u003Cp\u003EPhase resolved excitation into the states He(33S), Ar(2p1), O(3p5P) and O(3p3P).
