Background:

• Commissioning of a new hard X-ray engineering applications beamline (BL-02) at the Indian synchrotron source, Indus-2, in March 2019.
• The beamline is based on bending magnet technology and supports white, pink, and monochromatic X-ray beams.

Purpose of the Study:

• To describe the design, layout, optics, and operational modes of the BL-02 beamline.
• To detail the experimental capabilities for engineering applications, including stress, texture, and elastic constant measurements.
• To present validation experiments and discuss future enhancements for micro- and nano-structure characterization.

Main Methods:

• Utilizes X-ray diffraction in energy-dispersive and angle-dispersive modes.
• Employs an open-cradle six-circle diffractometer with a 12 kg load capacity.
• Incorporates a high-resolution mode for line profile analysis.

Main Results:

• The beamline is operational and capable of various beam modes.
• Demonstrated capabilities in stress, texture, and elastic constant measurements for bulk and thin-film samples.
• Validation experiments confirm design parameters and beamline performance.

Conclusions:

• The BL-02 beamline is a unique facility at Indus-2 for diverse engineering applications.
