abstract = {A design for a sample cell system suitable for high
temperature Quasi-Elastic Neutron Scattering (QENS)
experiments is presented. The apparatus was developed at the
Spallation Neutron Source in Oak Ridge National Lab where it
is currently in use. The design provides a special sample
cell environment under controlled humid or dry gas flow over
a wide range of temperature up to 950 °C. Using such a
cell, chemical, dynamical, and physical changes can be
studied in situ under various operating conditions. While
the cell combined with portable automated gas environment
system is especially useful for in situ studies of
microscopic dynamics under operational conditions that are
similar to those of solid oxide fuel cells, it can
additionally be used to study a wide variety of materials,
such as high temperature proton conductors. The cell can
also be used in many different neutron experiments when a
suitable sample holder material is selected. The sample cell
system has recently been used to reveal fast dynamic
processes in quasi-elastic neutron scattering experiments,
which standard probes (such as electrochemical impedance
spectroscopy) could not detect. In this work, we outline the
design of the sample cell system and present results
demonstrating its abilities in high temperature QENS
experiments.},
