A rapid and accurate method of finding light leaks in photomultiplier systems
A rapid method of finding light leaks in photomultiplier systems is described, in which an audible signal derived from the light level is produced. It uses equipment commonly available inExpand
The effect of magnetic field on the frequency dependent loss in amorphous silicon
Abstract Measurements of the frequency dependent magnetoconductance of a-Si and a-Si:H films in the percolation region and at low temperatures are discussed

Dynamical equilibration of a spatially periodic flow of conducting fluid with an embedded magnetic field : toward a self-consistent alpha-squared dynamo model
Spatially periodic flows possessing helicity exhibit dynamo action. One such flow studied by G.O. Roberts serves as the model in this thesis. The first results detail the structure of the flow,Expand
