Life Sciences
LS-CAT, APS Sector 21 is a canted undulator beamline with the downstream undulator providing X-rays to two stations via fixed energy diamond Laue monochromators. Flux on 21-ID-G is 10-15% lower than on 21-ID-F since it is after the other monochromator in series. Energy is fixed near 12.7 keV to enable selenium SAD phasing.
