  PoGOLino is a balloon-borne scintillator-based experiment developed to study
the largely unexplored high altitude neutron environment at high geomagnetic
latitudes. The instrument comprises two detectors that make use of LiCAF, a
novel neutron sensitive scintillator, sandwiched by BGO crystals for background
reduction. The experiment was launched on March 20th 2013 from the Esrange
Space Centre, Northern Sweden (geomagnetic latitude of $65^\circ$), for a three
hour flight during which the instrument took data up to an altitude of 30.9 km.
The detector design and ground calibration results are presented together with
the measurement results from the balloon flight.
