(Left) Calculated separation between the main beam and the +1st and −1st diffracted beams at the position of BIU1 as a function of the X-ray energy for the two different grating pitches currently installed at FXE. Right: image of the 0th, 1st and −1st X-ray beam diffracted by one of the 150 nm-pitch diamond gratings as seen by BIU1. |
