      Beamline Description
      FXI will house a Transmission X-ray Microscope (TXM) with 30 nm spatial resolution and 20-40 micron field of view. At 500 mA NSLS-II operation, the expected exposure time per image is < 100 ms. The TXM is also capable of nanoXANES, which will allow for the identification of chemical states of some elements. The FXI beamline is in the contingency scope of the NEXT project

      5-11 keV Si (111) DCM Energy resolution = 1.4 x 10-4 20-40 microns

      Source Type
      damping wiggler (DW100)

      Optical System
      Collimating mirror - DCM - Toroidal mirror. Energy bandwidth is Si(111) or ~ 1.4 x 10-4. Toroidal mirror focuses beam onto a secondary source (~ 260 um H x 240 um V) about 2 m upstream of the TXM. The TXM condenser will focus the secondary source to about 12-14 um spot on the sample. Condenser agitation or a beam disperser will increase the focus size on the sample to ~ 20-40 um field of view.

      Experimental Apparatus
      Transmission X-ray Microscope (XRADIA). 30 nm spatial resolution. 20-40 micron field of view. Some in-situ sample environmental cells are available.
