A hard X-ray engineering applications beamline (BL-02) was commissioned recently and started operation in March 2019 at the Indian synchrotron source, Indus-2. This bending-magnet-based beamline is capable of operating in various beam modes, viz. white, pink and monochromatic beam. The beamline utilizes the X-ray diffraction technique in energy-dispersive and angle-dispersive modes to carry out experiments mainly focused on engineering problems, viz. stress measurement, texture measurement and determination of elastic constants in a variety of bulk as well as thin-film samples. An open-cradle six-circle diffractometer with ∼12 kg load capacity allows accommodation of a wide variety of engineering samples and qualifies the beamline as a unique facility at Indus-2. The high-resolution mode of this beamline is suitably designed so as to carry out line profile analysis for characterization of micro- and nano-structures. In the present article the beamline is described starting from the beamline design, layout, optics involved, various operational modes and experimental stations. Experiments executed to validate the beamline design parameters and to demonstrate the capabilities of the beamline are also described. The future facilities to be incorporated to enhance the capabilities of the beamline are also discussed.

BL-02：用于 Indus-2 同步加速器源工程应用的多功能 X 射线散射和衍射光束线

一条硬 X 射线工程应用光束线 (BL-02) 最近已投入使用，并于 2019 年 3 月在印度同步加速器源 Indus-2 开始运行。这种基于弯曲磁铁的光束线能够在各种光束模式下运行，即。白色、粉红色和单色光束。光束线利用X射线衍射技术在能量色散和角度色散模式下进行主要针对工程问题的实验，即。应力测量、纹理测量和各种体块和薄膜样品的弹性常数测定。具有约 12 kg 负载能力的开放式支架六圆衍射仪可以容纳各种工程样品，并使光束线成为 Indus-2 的独特设施。该光束线的高分辨率模式经过适当设计，以便进行线轮廓分析，以表征微米和纳米结构。在本文中，从光束线设计、布局、涉及的光学、各种操作模式和实验站开始描述光束线。还描述了为验证光束线设计参数和演示光束线能力而执行的实验。
