ENERGY & WAVELENGTH CONFIGURATION SER-CAT beamline 22-ID-D will usually be set to 1.00 Å wavelength for the beginning of your time-slot, but both MAD and SAD experiments often require changes of this parameter. The method for accomplishing a wavelength change on 22-ID-D is given below: 22-ID-D: one may enter desired energy in eV (note: NOT keV!) - OR... one may enter desired energy in wavelength (lambda, measured in Å) note that the undulator gap energy will be slightly higher in eV than the desired energy; this is normal, and is a function of APS calibration considerations 22-ID-E: this will be a "fixed wavelength" beamline, delivering 12,700 eV x-rays note that the undulator gap energy will be slightly higher in eV than the desired energy; this is normal, and is a function of APS calibration considerations
