  We present a detector apparatus, DireXeno (DIRectinal Xenon), designed to
measure the spatial and temporal properties of scintillation in liquid xenon to
very high accuracy. The properties of scintillation are of primary importance
for dark matter and neutrinoless double beta decay experiments, however the
complicated microphysics involved limits theoretical predictions. We will
explore the possibility that scintillation emission exhibits correlation in
light emission such as super-radiance, which depends on the type of
interaction. Such properties of scintillation light may open a new window for
background rejection as well as directionality measurements. We present the
technical design and the concepts driving it, and demonstrate that statistical
treatment will enable detecting anisotropy of as little as 10% of the photons.
We show results from commissioning runs in which the detector operated for over
44 days in stable conditions. The time resolution for individual photons in
different PMTs was measured to be $\lesssim1.3$ ns FWHM, corresponding to
$\lesssim0.55$ ns (1 $\sigma$).
