Book Description
Abstract: The Florida State John D. Fox Superconducting Accelerator Laboratory is developing a new experimental program, which is targeting nuclear astrophysics and structure of exotic nuclei. An essential part of this program is construction of the large area, position sensitive neutron detector. The detector will extend significantly the set of tools available for nuclear physics experiments at FSU and would allow a whole new class of experiments to be performed. The large area, position sensitive neutron detector array has been installed in the target hall at the Florida State University John D. Fox Accelerator Lab. The detector is composed of 12 long bars of plastic scintillator. Calibration and optimization of this detector is the main goal of the work presented.

Book Description
A standard fast reactor spectrum can be created by the partial moderation of the U-235 fission spectrum in an air cavity. Spherical natural uranium shells are driven by thermal neutrons from a thermal column. The uranium is placed at the center of a spherical graphite hohlraum to reduce the anisotropic effect of a planar source of thermal neutrons. The Oregon State University (OSU) fast neutron spectrum facility design employs this method which is being used by Albert Fabry in Mol, Belgium and the NISUS assembly in London, United Kingdom, to create a fast neutron spectrum. The OSU facility uses the ther malizing column of a TRIGA Mark II reactor for a thermal neutron source. The mechanical design is presented showing the location of the facility, the aluminum container and internals, and the transport assembly. Two computer codes are introduced in the nuclear design. SLAB is a first approximation diffusion theory code which justifies the use of one foot of graphite backed with water in place of "infinite graphite." FASTSPEC is a diffusion theory approximation code in spherical geometry which shows that the design will produce a spectrum characteristic of a fast reactor. Phase I operation is a mechanical test, health physics evaluation, and a thermal neutron calibration of the facility with a thermal neutron absorber in place of the uranium. The data for phase I is included. Phase II operation will be the insertion of an uranium driver shell and the calibration of the fast spectrum. Only phase I is complete at this time.
