- Be Windows
- front end: 0.010" thick; 8.6 m from source
- exit window: 0.020" thick
- Monochromator
- Double flat crystal monochromator with fixed exit geometry; Bragg angle range is 10
degrees - 37 degrees; or flat Si(111) and Si(220) crystals operated side-by-side, each 100
mm wide; sagitally focusing Si(111) crystals (magnification 0.23-0.40); high precision
rotary energy scale; operates in high vacuum; located 16.5 meters from the source.
- Mirror
- For harmonics rejection and vertical focusing (0.3 mm FWHM); flat cylindrically bent
mirrors; independent choice of mirror angle and focal length; located 18.2 meters from the
source; magnification 0.13-0.29.
