Air Bearing Dual Crystal Monochromator
This cutting-edge monochromator utilizes an air bearing rotary stage goniometer with a canted undulator crystal cage. The device has a high speed direct drive torque motor with a frictionless, ultra-smooth bragg drive and has zero backlash. The indirectly cooled Si(111) and Si(311) crystal sets have withstood a high heat load at 150mA ring current. The enery range is 2.4 to above 30 keV and the 2nd crystal shows excellent temperature stability.
GSECARS 13 IDE is a dedicated XAFS / microprobe facility. The motivation for the new IDE monochromator was to effectively use the newly installed canted undulator source. The new source gives access to the K-edges of S, Cl, K and Ca for XAFS and fluorescence spectroscopies (XANES, EXAFS and XRF) while at the same time allowing access to L and/or K edges of heavy metals.
