Here, the dissociation of CO2 diluted in helium into CO is investigated. The diagnostic setup, combining TALIF with an ICCD camera, enables three-dimensional spatially resolved measurements of CO number densities below the CO-generating discharges. The measured distributions are compared to a basic three-dimensional diffusion model, showing good agreement and revealing the dominant transport mechanisms. Flow variation studies indicate that the gas flow inside the reactor follows a laminar, Poiseuille-like profile, while the transport behavior is consistent with literature values for the diffusion coefficient of CO, further validating the model. The high estimated local dissociation within the MCPA discharges (about 40%) results in saturation of CO fraction under increasing voltage. Combined with complementary diagnostics already presented for this discharge, including measurements of surface charges, electric fields, and atomic oxygen, this approach provides a suitable platform for systematic studies of plasma\u2013catalyst interactions.\u003C\/p\u003E\n","url":"https:\/\/rdpcidat.rub.de\/dataset\/3d-co-talif-distribution-below-micro-cavity-discharge-systematic-approach-plasma-catalysis","state":"Active","log_message":"Update to resource figure 6","private":true,"revision_timestamp":"Fri, 08\/07\/2026 - 11:06","metadata_created":"Fri, 07\/03\/2026 - 15:45","metadata_modified":"Fri, 08\/07\/2026 - 11:06","creator_user_id":"6c1e1ea8-664d-46f3-9669-db1ec7d49113","type":"Dataset","resources":[{"id":"d32518f1-7ed0-42c5-8982-5aeefabbb474","revision_id":"","url":"https:\/\/rdpcidat.rub.de\/sites\/default\/files\/figure_2.txt","description":"\u003Cp\u003ECalibration measurement showing the TALIF signal as a function of the admixed CO calibration gas concentration\u003C\/p\u003E\n","format":"data","state":"Active","revision_timestamp":"Fri, 08\/07\/2026 - 11:04","name":"figure 2","mimetype":"text\/plain","size":"201 bytes","created":"Fri, 07\/03\/2026 - 15:45","resource_group_id":"ee65a14f-0fc2-40e9-a4ba-e85030fe5102","last_modified":"Date changed  Fri, 08\/07\/2026 - 11:04"},{"id":"5ae3a1e9-8b95-44f5-a578-8d8378912c3a","revision_id":"","url":"https:\/\/rdpcidat.rub.de\/sites\/default\/files\/figure_3.txt","description":"\u003Cp\u003EMeasured fluorescence signal strength as a function of the squared laser pulse energy in a calibration measurement with 40ppm CO added to the gas flow.\u003C\/p\u003E\n","format":"txt","state":"Active","revision_timestamp":"Fri, 08\/07\/2026 - 11:04","name":"figure 3","mimetype":"text\/plain","size":"1.13 KB","created":"Tue, 07\/21\/2026 - 10:29","resource_group_id":"ee65a14f-0fc2-40e9-a4ba-e85030fe5102","last_modified":"Date changed  Fri, 08\/07\/2026 - 11:04"},{"id":"85f114fb-e98d-418c-81d1-283f44512a2e","revision_id":"","url":"https:\/\/rdpcidat.rub.de\/sites\/default\/files\/figure_4_0.zip","description":"\u003Cp\u003EWavelength TALIF excitation scan with plasma switched on (orange, 700V voltage amplitude) and switched off\u003C\/p\u003E\n","format":"zip","state":"Active","revision_timestamp":"Fri, 08\/07\/2026 - 11:04","name":"figure 4","mimetype":"application\/zip","size":"2.09 KB","created":"Tue, 07\/21\/2026 - 10:32","resource_group_id":"ee65a14f-0fc2-40e9-a4ba-e85030fe5102","last_modified":"Date changed  Fri, 08\/07\/2026 - 11:04"},{"id":"ec8e7b31-063d-44ca-bbef-2b46b6e15718","revision_id":"","url":"https:\/\/rdpcidat.rub.de\/sites\/default\/files\/figure_5_0.zip","description":"\u003Cp\u003EPoiseuille-like velocity profile for a total gas flow of 1slm for the centered xy-plane (z=2mm) and xz-plane.\u003C\/p\u003E\n","format":"zip","state":"Active","revision_timestamp":"Fri, 08\/07\/2026 - 11:04","name":"figure 5","mimetype":"application\/zip","size":"1.09 MB","created":"Tue, 07\/21\/2026 - 10:38","resource_group_id":"ee65a14f-0fc2-40e9-a4ba-e85030fe5102","last_modified":"Date changed  Fri, 08\/07\/2026 - 11:04"},{"id":"22afcf22-ae97-4333-9cf5-abeb67167591","revision_id":"","url":"https:\/\/rdpcidat.rub.de\/sites\/default\/files\/figure_6_1.zip","description":"\u003Cp\u003E(a) Measured three-dimensional CO density distribution where z = 0 corresponds to the measurement plane directly below the cavities.
