  The Optically Segmented Single Volume Scatter Camera (OS-SVSC) aims to image
neutron sources for nuclear non-proliferation applications using the kinematic
reconstruction of elastic double-scatter events. We report on the design,
construction, and calibration of one module of a new prototype. The module
includes 16 EJ-204 organic plastic scintillating bars individually wrapped in
Teflon tape, each measuring 0.5 cm$\times$0.5 cm$\times$20 cm. The scintillator
array is coupled to two custom Silicon Photomultiplier (SiPM) boards consisting
of a 2$\times$8 array of SensL J-Series-60035 Silicon Photomultipliers, which
are read out by a custom 16 channel DRS-4 based digitizer board. The electrical
crosstalk between SiPMs within the electronics chain is measured as 0.76% $\pm$
0.11% among all 16 channels. We report the detector response of one module
including interaction position, time, and energy, using two different optical
coupling materials: EJ-560 silicone rubber optical coupling pads and EJ-550
optical coupling grease. We present results in terms of the overall mean and
standard deviation of the z-position reconstruction and interaction time
resolutions for all 16 bars in the module. We observed the z-position
resolution for gamma interactions in the 0.3 MeVee to 0.4 MeVee range to be
2.24 cm$\pm$1.10 cm and 1.45 cm$\pm$0.19 cm for silicone optical coupling pad
and optical grease, respectively. The observed interaction time resolution is
265 ps$\pm$29 ps and 235 ps$\pm$10 ps for silicone optical coupling pad and
optical grease, respectively.
