Preliminary safety analysis of the B-C Cribs Controlled Area. [Hanford Reservation]

Description: Approximately 2,000 acres of land in the center of the Hanford Reservation is contaminated with an estimated 14 Ci of /sup 137/Cs and 81 Ci of /sup 90/Sr associated with animal wastes. Approximately half of this activity is located on (or within) 2.5 centimeters of the ground surface. The source of the contamination was the B-C Cribs and trenches which were used as liquid radioactive waste disposal sites during the 1950's. The mechanism for movement of radionuclides from the disposal site to th… more

Study of Photoproduction of Vector Mesons on Deuterium by 5. 5 GeV Linearly Polarized Photons

Description: The experimental results of a deuterium bubble chamber photoproduction study of half a million pictures at 5.5 GeV are presented. This experiment has been performed using a monoenergetic and linearly polarized photon beam facility at SLAC. At 5.5 GeV the beam polarization is greater than 90%, and the average FWHM of the beam energy spectrum is 0.6 GeV. The reaction ..gamma..d ..-->.. ..pi../sup +/..pi../sup -/d has been studied in detail. A clear sample of ..gamma..d ..-->.. rho/sup 0/d c… more

Analysis of the SIAM Infrared Acquisition System

Description: This report describes and presents the results of an analysis of the performance of the infrared acquisition system for a Self-Initiated Antiaircraft Missile (SIAM). A description of the optical system is included, and models of target radiant intensity, atmospheric transmission, and background radiance are given. Acquisition probabilities are expressed in terms of the system signal-to-noise ratio. System performance against aircraft and helicopter targets is analyzed, and background discrimina… more
