Question Spike in Deposited Energy/Time at Boundary of Detector

Hello. I am using a General Particle Source to fire 14.1 MeV neutrons directly at a 4cm plastic detector through a vacuum. Iím having GEANT output the global time and energy deposit to a file and I am graphing dE(total)/dt. At the time at which the primaries reach the back of the detector there is a large spike in power. (In addition, at the front of the detector the line is not vertical.) When I spliced a 200cm long detector into 2cm volumes it gave me many of these spikes.

Iím running Geant4.8.1 and Iím using the LHEP library in place of the physicslist file as in example 4. Thanks in advance.
