Lasers, experts, labs …How synchrotrons help
Quantity Definition Units Value
Flux # photons / Xph/ 1012 unit time sec
Fluence flux / unit area (Xph/sec)/ 1013 mm2
Brilliance fluence/ Xph/sec/ 1017 solid angle* (mm2-mrad2)
Brightness flux/solid angle* Xph/sec/ 1016 mrad2
* Sometimes defined in terms of bandwidth, e.g.brilliance = (fluence/solid angle)/bandwidth
Storage rings are large facilities with a number of resources in the vicinity
