The first coil is excited at a high-frequency, while the second coil is set at a medium frequency. The filling gas is argon, at atmospheric pressure. We use the modeling software COMSOL Multiphysics to describe the evolution of key parameters when: (i) the distance between the two coils changes, (ii) the power of the high frequency coil changes. We discuss the radial temperature profiles, the axial velocities and the heat convected at the end of the medium-frequency coil. The latter is compared with the total heat conduction to the plasma confinement tube wall."}, "doi_data": {"doi": "10.46298/ops.16373", "resource": "http://ops.episciences.org/16373", "collection": [{"item": {"@crawler": "iParadigms", "resource": "https://arxiv.org/pdf/2508.13858v5"}, "@property": "crawler-based"}, {"item": {"resource": {"value": "https://arxiv.org/pdf/2508.13858v5", "@mime_type": "application/pdf"}}, "@property": "text-mining"}]}, "keywords": ["Plasma Physics"], "@language": "en", "contributors": {"person_name": [{"surname": "Terraz", "@sequence": "first", "given_name": "Loann", "@contributor_role": "author"}, {"surname": "Alemu", "@sequence": "additional", "given_name": "Biruk", "@contributor_role": "author"}, {"surname": "Eizaguirre", "@sequence": "additional", "given_name": "Santiago", "@contributor_role": "author"}]}, "publisher_item": {"item_number": {"value": "16373", "@item_number_type": "article_number"}}, "acceptance_date": {"day": "06", "year": "2026", "month": "01", "@media_type": "online"}, "publication_date": {"day": "19", "year": "2026", "month": "01", "@media_type": "online"}, "@publication_type": "full_text"}, "journal_metadata": {"issn": {"value": "3076-1468", "@media_type": "electronic"}, "doi_data": {"doi": "10.46298/journals/ops", "resource": "http://ops.episciences.org"}, "@language": "en", "full_title": "Open Plasma Science"}}, "database": {"current": {"url": "http://ops.episciences.org/17313", "flag": "submitted", "type": {"title": "article"}, "dates": {"posted_date": "2026-01-15 11:26:26", "publication_date": "2026-01-19 19:27:28", "modification_date": "2026-01-19 19:27:28", "first_submission_date": "2025-08-20 14:37:41"}, "files": {"link": "http://ops.episciences.org/17313/pdf"}, "isTmp": false, "status": {"id": 16, "label": {"en": "published", "fr": "publié"}}, "volume": {"id": 1039, "year": "2025", "number": 1, "titles": {"en": "ICPIG 2025"}, "position": "3", "settings": {"is_open": true, "is_current_issue": false, "is_special_issue": true}, "descriptions": {"en": "The International Conference on Phenomena in Ionized Gases (ICPIG), now in its XXXVI edition, since 1953 has been a forum for the discussion of nearly all fields of plasma science, covering modelling and experiments, from the fundamentals of elementary processes, basic data and discharge physics (including transport and interaction with walls), to applications.
