Investigation of noise analysis techniques for the MIT heavy water lattice
Hauck, Frederick Hamilton

A reliable system for performing a Fourier analysis of a reactor noise signal has been constructed and utilized. Both auto- and cross-correlation techniques were used to study noise signals from the MITR hohlraum and the exponential lattice. As predicted by theory* the efficiency of the detectors used was insufficient to provide positive results. The lattice transfer function was electronically simulated and analyzed by the system confirming the reliability of the equipment. Several methods are suggested for increasing detector efficiencies to provide signal levels which will permit extraction of information about the kinetic behavior of the test lattice.
