The method is designed to improve beam flux by adjusting two mirrors within a target alignment time of 5\u2005min, thereby satisfying critical operational demands. The proposed PSO-based method incorporates three adaptations: (i) particle initialization and dynamics (which are modified to locate a narrow flux peak efficiently), (ii) mirror-movement optimization (which reduces the total mirror-travel time), and (iii) a termination condition (which balances the practical trade-off between alignment time and beam flux). Simulation results demonstrate the feasibility of achieving the alignment target and show that under the evaluated conditions the proposed method identified high-flux solutions more consistently than a general-purpose Gaussian-process-based Bayesian optimization method. Further, validation over a 15\u2005month deployment period on an operational beamline, during which the proposed method improved beam flux in 107 of 124 runs (86.3%), demonstrates its robustness and reliability.<\/jats:p>","DOI":"10.1107\/s1600577526008994","type":"journal-article","created":{"date-parts":[[2026,9,17]],"date-time":"2026-09-17T14:23:58Z","timestamp":1789655038000},"update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":0,"title":["Mirror alignment by particle swarm optimization for synchrotron radiation beamlines"],"prefix":"10.1107","volume":"33","author":[{"given":"Bunyo","family":"Okumura","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kunihiro","family":"Goto","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Akinobu","family":"Fujii","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6967-9574","authenticated-orcid":true,"given":"Takamasa","family":"Nonaka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tsukasa","family":"Shimizu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshihiro","family":"Ohama","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"329","published-online":{"date-parts":[[2026,10,5]]},"container-title":["Journal of Synchrotron Radiation"],"original-title":[],"link":[{"URL":"https:\/\/journals.iucr.org\/s\/issues\/2026\/06\/00\/vy5050\/vy5050.pdf","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.iucr.org\/s\/issues\/2026\/06\/00\/vy5050\/vy5050.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,10,29]],"date-time":"2026-10-29T16:37:44Z","timestamp":1793291864000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.iucr.org\/paper?S1600577526008994"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,10,5]]},"references-count":0,"journal-issue":{"issue":"6","published-online":{"date-parts":[[2026,11]]}},"alternative-id":["S1600577526008994"],"URL":"https:\/\/doi.org\/10.1107\/s1600577526008994","relation":{},"ISSN":["1600-5775"],"issn-type":[{"value":"1600-5775","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,10,5]]},"assertion":[{"value":"Journal of Synchrotron Radiation","order":0,"name":"journal","label":"Publication","explanation":{"URL":"https:\/\/journals.iucr.org\/s"},"group":{"name":"general","label":"General"}},{"value":"research papers","order":1,"name":"content_type","label":"Content type","explanation":{"URL":"https:\/\/journals.iucr.org\/s\/services\/notesforauthors.html"},"group":{"name":"general","label":"General"}},{"value":"Available","URL":"https:\/\/scripts.iucr.org\/cgi-bin\/citedin?vy5050","order":2,"name":"article_metrics","label":"Article metrics","group":{"name":"general","label":"General"}},{"value":"Yes","order":0,"name":"peer_reviewed","label":"Peer reviewed","group":{"name":"peer_review","label":"Peer review"}},{"value":"Single blind","order":1,"name":"review_process","label":"Review process","group":{"name":"peer_review","label":"Peer review"}},{"value":"2 June 2026","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication history"}},{"value":"28 August 2026","order":1,"name":"accepted","label":"Accepted","group":{"name":"publication_history","label":"Publication history"}},{"value":"5 October 2026","order":2,"name":"published_online","label":"Published online","group":{"name":"publication_history","label":"Publication history"}},{"value":"\u00a9 2026 Bunyo Okumura\n                      et al.","order":0,"name":"copyright","label":"Copyright","explanation":{"URL":"https:\/\/journals.iucr.org\/services\/copyrightpolicy.html"},"group":{"name":"copyright_and_licencing","label":"Copyright and licencing"}},{"value":"Creative Commons Attribution (CC-BY)","order":1,"name":"license","label":"Licence","explanation":{"URL":"https:\/\/creativecommons.org\/licenses\/by\/4.0\/legalcode"},"group":{"name":"copyright_and_licencing","label":"Copyright and licencing"}}]}}
