Upgraded imaging capabilities at the BAMline (BESSY II)

Area of Science:

• Synchrotron X-ray imaging
• Materials science
• Biology
• Cultural heritage
• Medicine

Background:

• The BAMline at BESSY II has been a key facility for over 20 years.
• Synchrotron X-ray imaging, particularly tomography, is crucial for nondestructive structural characterization.
• Previous limitations included longer scan times and restricted in situ/operando capabilities.

Purpose of the Study:

• To enhance the imaging capabilities of the BAMline.
• To enable faster data acquisition and more flexible experimental setups.
• To facilitate the study of dynamic processes at the second timescale.

Main Methods:

• Upgrade of the double-multilayer monochromator for flexible energy spectra.
• Installation of a new sCMOS camera-based detector for higher flux and reduced readout times.
• Integration of a slip ring for continuous sample rotation.

Main Results:

• Significantly reduced scan acquisition times.
• Optimized flux and energy resolution through flexible energy spectra.
• Enabled routine in situ and operando studies.
• Facilitated tomographic observation of processes on the second timescale.

Conclusions:

• The upgraded BAMline offers significantly enhanced synchrotron X-ray imaging capabilities.
• The improvements allow for more advanced and dynamic structural characterization across various scientific disciplines.
• The facility is now better equipped for cutting-edge research in materials science, biology, and beyond.
