{"id":"https://openalex.org/G5358917802","display_name":"Developments and Applications of Vortex Synchrotron Radiation","description":"We have developed a technology to add a new function to synchrotron radiation, which is widely used in various research areas as a light source in the ultraviolet to X-rays, and have developed its applications. Using a light source device called an undulator, we established a method of generating a light beam with a spatial structure such as an optical vortex or a vector beam in which the properties of light change on the cross section of the light beam. In addition, we conducted leading experiments using it. During this research, we have found a method to control the time structure of synchrotron radiation and have applied it to a leading experiment, which gave us and a clue for the next development.","funder_award_id":"17H01075","funder":{"id":"https://openalex.org/F4320334764","display_name":"Japan Society for the Promotion of Science","doi":"https://doi.org/10.13039/501100001691"},"funded_outputs":["https://openalex.org/W2531762302","https://openalex.org/W2588826849","https://openalex.org/W2735401200","https://openalex.org/W2744114040","https://openalex.org/W2883807042","https://openalex.org/W2968076640","https://openalex.org/W2985939687","https://openalex.org/W2994287531","https://openalex.org/W3042290435","https://openalex.org/W3138820284","https://openalex.org/W4282941125","https://openalex.org/W4312180213","https://openalex.org/W4381950662","https://openalex.org/W4390262832"],"funded_outputs_count":14,"parent_awards":[],"sub_awards":[],"sub_awards_count":0,"amount":28470000.0,"currency":"JPY","amount_usd":254598.72,"amount_usd_basis":"daily_rate","recipients":[],"recipient_countries":[],"recipient_regions":[],"research_scope":{"is_research":true,"basis":"funder_default","tier":1},"funding_type":"research","funder_scheme":"Grant-in-Aid for Scientific Research (A)","start_date":"2017-04-01","end_date":"2020-03-31","start_year":2017,"end_year":2020,"landing_page_url":"https://kaken.nii.ac.jp/en/grant/KAKENHI-PROJECT-17H01075/","doi":null,"provenance":"kaken","lead_investigator":{"given_name":"Masahiro","family_name":"Katoh","orcid":null,"role_start":null,"affiliation":{"name":"Institute for Molecular Science","country":"Japan","ids":[{"id":"https://nrid.nii.ac.jp/nrid/1000030185871","type":"nrid","asserted_by":"kaken"}]},"author":{"id":"https://openalex.org/A5045185048","display_name":"Masahiro Katoh","orcid":"https://orcid.org/0000-0001-9149-1500"},"institutions":[{"id":"https://openalex.org/I4210143791","display_name":"Institute for Molecular Science","ror":"https://ror.org/04wqh5h97","country_code":"JP","type":"facility","lineage":["https://openalex.org/I1319490839","https://openalex.org/I199525922","https://openalex.org/I4210143791"]}]},"co_lead_investigator":null,"investigators":null,"works_api_url":"https://api.openalex.org/works?filter=awards.id:G5358917802","primary_topic":{"id":"https://openalex.org/T10559","display_name":"Particle Accelerators and Free-Electron Lasers","score":0.6528,"subfield":{"id":"https://openalex.org/subfields/2208","display_name":"Electrical and Electronic Engineering"},"field":{"id":"https://openalex.org/fields/22","display_name":"Engineering"},"domain":{"id":"https://openalex.org/domains/3","display_name":"Physical Sciences"}},"topics":[{"id":"https://openalex.org/T10559","display_name":"Particle Accelerators and Free-Electron Lasers","score":0.6528,"subfield":{"id":"https://openalex.org/subfields/2208","display_name":"Electrical and Electronic Engineering"},"field":{"id":"https://openalex.org/fields/22","display_name":"Engineering"},"domain":{"id":"https://openalex.org/domains/3","display_name":"Physical Sciences"}},{"id":"https://openalex.org/T10490","display_name":"Orbital Angular Momentum in Optics","score":0.3315,"subfield":{"id":"https://openalex.org/subfields/3107","display_name":"Atomic and Molecular Physics, and Optics"},"field":{"id":"https://openalex.org/fields/31","display_name":"Physics and Astronomy"},"domain":{"id":"https://openalex.org/domains/3","display_name":"Physical Sciences"}},{"id":"https://openalex.org/T11367","display_name":"Particle accelerators and beam dynamics","score":0.0045,"subfield":{"id":"https://openalex.org/subfields/3106","display_name":"Nuclear and High Energy Physics"},"field":{"id":"https://openalex.org/fields/31","display_name":"Physics and Astronomy"},"domain":{"id":"https://openalex.org/domains/3","display_name":"Physical Sciences"}}],"keywords":[{"id":"https://openalex.org/keywords/optical-vortex","display_name":"optical vortices","score":0.891},{"id":"https://openalex.org/keywords/vector-beams","display_name":"vector beams","score":0.99},{"id":"https://openalex.org/keywords/undulator","display_name":"undulator","score":0.64},{"id":"https://openalex.org/keywords/structured-light","display_name":"structured light","score":0.735},{"id":"https://openalex.org/keywords/synchrotron-radiation","display_name":"synchrotron radiation","score":0.748},{"id":"https://openalex.org/keywords/light-sources","display_name":"light sources","score":0.513}],"sustainable_development_goals":[],"institution_awarded":[{"id":"https://openalex.org/I4210143791","display_name":"Institute for Molecular Science","ror":"https://ror.org/04wqh5h97","country_code":"JP","type":"facility","lineage":["https://openalex.org/I1319490839","https://openalex.org/I199525922","https://openalex.org/I4210143791"]}],"updated_date":"2026-11-13T03:01:57.000Z","created_date":"2026-07-13T04:17:19.000Z"}
