Powder diffraction, in situ phase transformation and stability, crystallography, spectroscopy, phase identification and residual strain measurement, high temp x-ray diffraction. This beamline was the first to take light on the x-ray ring. It is equipped with a Si (111) horizontally focusing double crystal monochromator that provides useful flux from 3.6 to 20 keV. The angular acceptance is 10 milliradians and because of the focusing delivers the beam to a spot size 1.5 by 1.0 mm spot. The beamline is essentially unchanged from its original optical configuration however, due to its unique capabilities, the NSLS allocated some of its facilities initiative funding to the replacement of its first mirror, which was installed in 1998. X14A is optimized to be a very flexible diffraction station. It is equipped with a six circle Huber diffractometer with split chi-ring, crystal analyzers (Si, Ge, LiF, graphite crystals); CAMAC multi-channel analyzer; sample chambers for polycrystalline and gaseous materials; proportional counters, and an avalanche photodiode detector. In addition a four-lamp thermal image capillary furnace (up to 1700°C), a plate sample furnace (up to 900°C) with hemisherical Be dome and a Displex cryostat are available by special arrangement with the PRT. X14A recently participated in the Industrial Research Program at the Photon Science Directorate (PSD) and has been collaborating with the Iindustrial Research Program by providing more general user time for industrial research and especially energy related research projects, such as in situ XRD studies on battery materials. X14A beamline has been improved and has new capabilities added by the PSD Industrial Research Program. It includes a 640 channel Si strip detector which is a key instrument to run user program at X14A; a four-lamp thermal image capillary furnace (up to 1700°C) and its cooling and control system for in-situ high-T powder diffraction; a VAC controlled atmosphere system (glove box); a VMP3 cycler (for in situ battery studies) and a tube furnace (100°C to 1100°C) for sample processing which are available to the beamline users through the PSD Iindustrial Research Pprogram.
