Often, studying these HED objects requires very high spatial resolution, which is limited by astigmatism when using spherically bent crystals. By using toroidal-shaped crystals instead, astigmatism can be reduced and the overall spatial resolution of the instrument improved. Here, the development and characterization of a laser-gated x-ray radiography platform at the National Ignition Facility using a toroidal crystal is presented. This includes measurements of the spatial and temporal profile, which is determined by the x-ray source. To properly validate the reduced astigmatism, a new multi-plane grid approach was implemented, which, for the first time, allows a depth of field measurement, alignment verification and x-ray source size estimate in a single shot, demonstrating the current platform\u2019s capability to provide sub-10 \u03bcm resolution over a 0.9\u00a0mm depth of field with a temporal resolution of 110\u00a0ps.<\/jats:p>","DOI":"10.1063\/5.0252071","type":"journal-article","created":{"date-parts":[[2025,4,7]],"date-time":"2025-04-07T15:13:11Z","timestamp":1744038791000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":4,"title":["Development and characterization of a laser-gated, high resolution x-ray radiography platform for high energy density experiments using toroidally bent crystals"],"prefix":"10.1063","volume":"96","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0998-9479","authenticated-orcid":false,"given":"T.","family":"Ebert","sequence":"first","affiliation":[{"name":"Lawrence Livermore National Laboratory , Livermore, California 94550,","place":["USA"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5081-7890","authenticated-orcid":false,"given":"G.
