This dispersion-strengthened copper alloy is a proprietary material and detailed technical data of interest to the synchrotron community is limited. The results from the research program have allowed new design criteria to be established for GlidCop<jats:sup>\u00ae<\/jats:sup>X-ray absorbers based upon the thermomechanically induced fatigue behavior of the material. X-ray power from APS insertion devices was used to expose 30 GlidCop<jats:sup>\u00ae<\/jats:sup>samples to 10000 thermal loading cycles each under various beam power conditions, and all of the samples were metallurgically examined for crack presence\/geometry. In addition, an independent testing facility was hired to measure temperature-dependent mechanical data and uniaxial mechanical fatigue data for numerous GlidCop<jats:sup>\u00ae<\/jats:sup>samples. Data from these studies support finite element analysis (FEA) simulation and parametric models, allowing the development of a thermal fatigue model and the establishment of new design criteria so that the thermomechanically induced fatigue life of X-ray absorbers may be predicted. It is also demonstrated how the thermal fatigue model can be used as a tool to geometrically optimize X-ray absorber designs.<\/jats:p>","DOI":"10.1107\/s1600577517001734","type":"journal-article","created":{"date-parts":[[2017,2,20]],"date-time":"2017-02-20T18:22:34Z","timestamp":1487614954000},"page":"402-412","update-policy":"https:\/\/doi.org\/10.1107\/cm_01","source":"Crossref","is-referenced-by-count":7,"title":["Establishment of new design criteria for GlidCop<sup>\u00ae<\/sup>X-ray absorbers"],"prefix":"10.1107","volume":"24","author":[{"given":"Jeff T.","family":"Collins","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jeremy","family":"Nudell","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gary","family":"Navrotski","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8902-3636","authenticated-orcid":true,"given":"Zunping","family":"Liu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Patric","family":"Den Hartog","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"329","published-online":{"date-parts":[[2017,2,20]]},"reference":[{"key":"ve5065_bb1","first-page":"625","volume":"10","author":"Basquin","year":"1910","journal-title":"Proc.
