Features
XFEL DCM Chamber
This Double Crystal Monochromator is specially developed for the XFEL beam line along with UHV environment and precise-positioning technology. Stability of the crystal posture is most significant.
- UHV compatible design, ultimate pressure Less than 5x10-8Pa
- Compact design
- Achieved 3.7°-30° of the Bragg angle (Rotation range: -1°-30°)
- Granite mount for minimisation of low-frequency oscillation
- Crystal cage mounted on rigid drive shaft for high stability
- Stability pitch angle of Crystal less than 0.5μrad/1hr and less than 1μrad/24hr
- Size of crystal 90(L) x 30(W) x 40(H)mm
- Water cooling system for first and second crystals
