  We present the first prototype of a novel thermal neutron detector using the
time projection method. The system consists of 8 TimePix ASICS with
postprocessed InGrid meshes. Each ASIC has 256 x 256 pixels of 55 mum x 55mum
in size with the capability to measure charge or time. This allows to visualize
entire conversion particle tracks with their spatial and time information and,
by using event reconstruction algorithms, discriminate against the background
of others. By using the Scalable Readout System the detector as presented here
could also be upscaled to much larger active areas. In the current
configuration we could achieve a spatial resolution of $\sigma = (115\pm8)$
mum.
