Beamline 7-BM-B: Fluid Dynamics Beamline

X-ray Science Division, APS
Physics

Description

The 7-BM beamline is dedicated to time-resolved x-ray radiography, tomography, and fluorescence spectroscopy using a high-intensity microbeam. The major application of the beamline is the study of transient fluid flowfields (for example, high-speed liquid sprays and compressible gas flowfields). However, other types of time-resolved radiography measurements can also be accommodated. Additionally, the beamline performs hard x-ray tomography using filtered BM white beam.

 

Supported Techniques

  • Radiography
  • Tomography
  • Microfluorescence (hard x-ray)

Beamline Controls and Data Acquisition

EPICS beamline controls using Python for scripting and  oscilloscopes for data acquisition.

Detectors

  • Silicon PIN Diode
  • Vortex Silicon Drift Diode, 100 mm^2 Active Area
  • Scintillator crystals
  • Optical microscopes and cameras

Special Capabilities

  • Wide bandpass from double multilayer monochromator and KB focusing mirrors allow for a high flux microprobe from a bending magnet source. Use of single bounce from the monochromator multilayer allows for high energy operation at wide bandpass.
