abstract = {A new sample environment is introduced for the study of
soft matter samples in electric fields using small-angle
neutron scattering instruments. The sample environment is
temperature controlled and features external electrodes,
allowing standard quartz cuvettes to be used and conducting
samples or samples containing ions to be investigated
without the risk of electrochemical reactions occurring at
the electrodes. For standard 12.5 mm quartz cuvettes, the
maximum applied field is 8 kV/cm, and the applied field may
be static or alternating (up to 10 kHz for 8 kV/cm and up to
60 kHz for 4 kV/cm). The electric fields within the sample
are calculated and simulated under a number of different
conditions, and the capabilities of the setup are
demonstrated using a variety of liquid crystalline samples.
Measurements were performed as a function of temperature and
time spent in the electric field. Finally, the advantages,
drawbacks, and potential optimization of the sample
environment are discussed with reference to applications in
the fields of complex soft matter, biology, and
electrorheology.},
