This approach optimizes focus size and maximizes peak intensity while minimizing aberrations. Wavefront errors are quantitatively correlated with alignment deviations \u2013 incidence angle, perpendicularity and astigmatism \u2013 via Legendre polynomial analysis. These errors are subsequently corrected through a straightforward optimization process. Implemented at the SPring-8 Angstrom Compact Free-Electron Laser (SACLA), the system consistently achieves a reproducible XFEL focus below 150\u2005nm \u00d7 200\u2005nm within 10\u2005min. Routine operation at SACLA demonstrates the reliability and efficacy of this method, enabling rapid restoration of optimal nanofocusing conditions.<\/jats:p>","DOI":"10.1107\/s1600577525008434","type":"journal-article","created":{"date-parts":[[2025,10,9]],"date-time":"2025-10-09T08:43:06Z","timestamp":1759999386000},"page":"1534-1538","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":0,"title":["Automated alignment of XFEL nanofocusing mirrors via wavefront optimization"],"prefix":"10.1107","volume":"32","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5476-4327","authenticated-orcid":true,"given":"Jumpei","family":"Yamada","sequence":"first","affiliation":[{"id":[{"id":"https:\/\/ror.org\/035t8zc32","id-type":"ROR","asserted-by":"publisher"}],"department":["Research Center for Precision Engineering, Graduate School of Engineering"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gota","family":"Yamaguchi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ichiro","family":"Inoue","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0545-9737","authenticated-orcid":true,"given":"Taito","family":"Osaka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuichi","family":"Inubushi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2472-1684","authenticated-orcid":true,"given":"Makina","family":"Yabashi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"329","published-online":{"date-parts":[[2025,10,24]]},"reference":[{"key":"zhu5010_bb1","doi-asserted-by":"crossref","first-page":"5698","DOI":"10.1364\/AO.51.005698","volume":"51","author":"Bon","year":"2012","journal-title":"Appl.
