21-ID-F: Sector 21 - Insertion Device

LS-CAT
Life Sciences

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