We present the new synchrotron beamline (BL-I11) at Diamond Light Source (DLS) which is a dedicated powder diffraction instrument. The beamline receives an intense and highly collimated X-ray beam generated by an in-vacuum undulator. With the simple optics (a double-crystal monochromator, harmonic rejection mirrors and slits), a high purity beam of low energy-bandpass X-rays in the range 5-30 keV is delivered at the sample. The heavy duty diffraction instrument is designed to have the flexibility to house a variety of sample environments and to have two detection systems to collect high quality diffraction data, i.e. multi-analysing crystals for high angular resolution experiments and a fast position sensitive detector for time-resolved studies. When fully operational, BL-I11 will be a powerful state-of-the-art dedicated user facility for high resolution (d-space and time) diffraction studies of polycrystalline materials under ambient and non-ambient conditions. As the facility has very recently become operational offering the high resolution (angular) mode, the beam performance characteristics measured during the commissioning phase are presented. In addition, the first results obtained from real sample(s) are given to show the capability of this new instrument.
