N2 - We have developed a high-P low-T fluid/gas cell to perform in-situ and real-time neutron diffraction and inelastic neutron scattering using LANSCE's High-Pressure Preferred- Orientation (HIPPO) diffractometer and Filter Difference Spectrometer (FDS), respectively. HIPPO covers a wide range of Q (scattering vector, 0.13-52.4 Å-1) values, and its multiple detectors are configured to provide high counting rates at different diffraction angles. FDS measures vibrational spectra in the wavenumber range 40-4000 cm-1 with a resolution of 3-5% (using the maximum entropy 5 methods for data analysis) and offers several advantages over its optical counterparts (infrared, Raman) such as greater sensitivity to hydrogen and no selection rules. These setups are thus ideal for in-situ real-time studies of formation/decomposition of hydrogen inclusion compounds as time evolves at various pressure and temperature conditions. Using HIPPO and FDS, we have characterized a series of porous hydrogen storage materials.
