Abstract (Summary)

With neutrino detectors continuously becoming larger and more expensive every day it is vital that the next generation of scientists work against this tide to make smaller and smarter neutrino detectors where it is possible. Of course ultimately long distance neutrino detection requires large instruments, but near reactor detectors can be small and prove out techniques for later larger applications. In this spirit we present to you the miniTimeCube (mTC), a prototype for a small compact portable antineutrino detector with directional capability. While we did not achieve everything we had hoped on our first attempt, our group has a set a precedent in the field of a dozen competitors. We present a unique model for fitting neutron directionality which produces an agreement between the average truth and fitted directional vector of cos(&thetas;) = .998 +/-.002, an impressive result considering neutron directionality has never been achieved in a single hard volume target. We will discuss the detector construction, our simulations and reconstructions, our results from our neutrino experiment at the test reactor at NIST, and our neutron directionality test here at the University of Hawaii at Manoa.
