The Construction Of A Fermi Neutron Chopper For Cross Section Measurements, Cleon Marion Mobley
The Construction Of A Fermi Neutron Chopper For Cross Section Measurements, Cleon Marion Mobley
Masters Theses
"A Fermi neutron chopper and control system has been constructed and put into operation at the end of the UMR Reactor thermal column.
The operation of the chopper has been demonstrated by reproducing the slow neutron cross section data for aluminum and by measuring the previously undetermined slow cross section of cobalt.
The chopper which is powered by a series DC motor consists of 34 cadmium plated stainless steel blades separated by 1/16 inch aluminum spacers. The design incorporates the better characteristics of the Brookhaven and Argonne slow choppers. Speed regulation is accomplished using a silicon controlled rectifier feed back …
