25A Coherent X-ray Scattering

Endstations

  • Hexapod as sample stage (x, y, z, pitch, yaw, and roll) (mounting holes M4*4 60mm * 60mm)
    If you want to mount your own devices on the sample stage. Please contact us first.
  • Detector system: photodiode, Dectris EIGER X 1M (WAXS/GIWAXS), Dectris EIGER X 16M (SAXS/GISAXS/XPCS)
  • 12 m vacuum pipe (selectable distance: 2, 3, 4, 5, 6, 8, 10, 12 meters)
  • On-axial microscope (at 1X, 2.5μm/pixel, upto 10X)

Sample Environments

  • Liquid/solid sample cells with temperature control (water-chiller and heating rods)
  • 9-holes/capillary easy-mounting sample plate without temperature control
  • Piezoelectric stage with encoder for CDI and ptychography
  • Film holder for GISAXS and GIWAXS
  • Tensile stage
  • LB trough

Control System and Data Analysis

EPICS and CS-Studio GUI for beamline and endstation control

Beamline Control


Integrated Endstation Control (Sample Stage & Detector Settings)


On-axial Microscope Viewport (cross hair is beam position)


Data reduction (SAXS) and calculation (XPCS) programs with graphic interface


SAXS Data Reduction (CS-Studio GUI)
Currently GUI is moved to QT5 from CS-Studio. Please see 'Resource' to get more information. 


XPCS Calculation Program (CS-Studio)
Currently GUI is moved to QT5 from CS-Studio. Please see 'Resource' to get more information.

Bragg CDI

We have installed the equipments for the Bragg CDI measurements. The design concept is as below figure. There is an additional rotational stage for a detector, in-vacuum Eiger X 1M. The travelling range of sample to detector distance is from few tens centermeter to 2 meters.
