AEC Research and Development Report: Yield of Kr-85 and Xe-133 in the Thermal Neutron Fission of U-235 and Yield of Kr-85 in the Thermal Neutron Fission of Pu-239

Description: We have made absolute radiochemical measurements of the yields of Kr-85 and Xe-133 in the thermal neutron fission of U-235, and of Kr-85 in the thermal neutron fission of Pu-239. For Kr-85 in U-235 fission, the mean of eight measurements gives the ratio, X/T, of fission yield to half-life: X/T = 0.0253%/yr; σ = 1.59%; 99-1 error of the mean = 2.41%. For Kr-85 in Pu-239 fission, the mean of three measurements gives X/T = 0.0092%/yr; σ = 4.3%. Here σ is the standard deviation of a single measurem… more

AGS Performance and Plans

Description: The scope of the AGS complex has expanded rapidly during the three years since an accelerated beam was first obtained. Demand for research time far exceeds the amount available although facilities have been much increased. At the same time, experiments are being designed which are more complicated than previous ones and which make more stringent demands on the accelerator and on its auxiliary equipment. There is a continuous trend of experiments to particle beams of greater momentum, as the exp… more

An Alcohol Drip Apparatus for the Sliding Microtome

Description: In wet sectioning of celloidin embedded tissue it is necessary to maintain a layer of alcohol on the knife and on the surface of the block. The alcohol acts as a lubricant and also prevents drying of the block. The application of alcohol may be done by hand or mechanically. To apply the alcohol by hand while operating the microtome slows down the cutting operation, unless the operator is ambidextrous. In addition, stopping and starting the knife to apply alcohol results in an extensive wasting … more

Alternating Gradient Magnets

Description: The angle by which a magnet deflects the trajectory of a particle in the x-z plane is proportional to the integral [integral not transcribed] taken over the trajectory wherever B≠0. Alternating gradient focusing is achieved by designing magnets so that I=I(x) varies linearly with x over a suitable x interval. Usually this is done by shaping the poles to give a linear variation of By with x while keeping the length of the magnet constant for different x. Certain advantaged may be gained by varyi… more

Analysis of Cell Population Kinetics

Description: The relation between trace kinetic parameters of cell populations and the statistics used in studies on cell populations is discussed. It is pointed out that responses in cell populations are complex and subject to many perturbations. Some of these are discussed. It is concluded that a complete check list of sources of error is required for studies of great accuracy, and a calculus to help in combining heterogeneous data is needed for studies of systems of great complexity.

Analytic Spin Functions of a Single Variable

Description: There has been considerable recent interest in the development of spin representations which are operations upon analytical functions. The familiar Pauli spin matrix representation, has been sufficient for the solutions of most problems involving nonrelativistic electron spin, but it is to be hoped that, for some problems, an "analytic" representation could be found which has greater physical significance. The new representations that have been presented all hae spin functions of two or more va… more

The Angular Dependence of Thermal Neutron Spectra in Lattices

Description: This technical report discusses techniques that have been developed for "computing the angular thermal flux spectrum emerging from a lattice. These methods are applied to water lattices and it is found that the computed spectra are sensitive to the geometrical description of the lattice, but insensitive to the anisotropic scattering by water. Comparisons with measured spectra indicate that corrections for gradients and the finite size of the experimental lattice are important." -- from abstract… more

Antibody Formation by Transplanted Bone Marrow, Spleen, Lymph Node and Thymus Cells in Irradiated Recipients

Description: The role of the marrow as a site for antibody formation has been considered for many years. In 1912 Ludke reported the appearance of antibody in cultures of marrow cells obtained from previously immunized rabbits. Specific agglutinins for killed typhoid bacilli and lysins for ox red cells and sheep red cells were detected in the culture media 2 to 5 days later. However, the cultured cells failed to produce antibody when these antigens were added to the media. Similar findings by Reiter, Przygod… more

Antiproton-Proton Two-Prong Interactions at 3.25 Bev/c

Description: A study is being made of two-prong antiproton interactions in hydrogen at 3.25 Bev/c. About 2250 two-prong events were measured on automatic digitized machines and their reconstruction and analysis were performed with standard programs. Of the total number of events 1003 were classified as elastic interactions. About 500 inelastic events were examined using bubble density estimates in addition to criteria based on distribution values in the classification procedure. The inelastic events in whic… more

The Application of Inert Fluidized Beds to the Volatility Reprocessing of Reactor Fuels

Description: In the reprocessing of spent solid fuels from nuclear reactors by direct volatilization, one of the major problems is the removal of heat from the highly exothermic gas-solid reactions. The use of fluidized beds of inert granular material as heat transfer media to control these exothermic reactions forms the basis of one approach to volatile reprocessing which is under development at BNL The engineering scale work carried out under this development program is discussed.

The Approximation with Anisotropic Effects for Cylindrical Geometry

Description: The method of spherical harmonic tensors developed Mark for solving the Boltzmann transport equation in isotropic media is herein extended to anisotropic media for cylindrical geometry. A formal solution is given for the case of two concentric cylindrical media, A and B, but no numerical work has yet been done. The following treatment differs from a similar one by the H. K. Ferguson Co. in that the external medium B is assumed to be both a neutron absorber and finite in extent rather than a non… more

Autoradiographic Study on the Origin and Fate of Small Lymphoid Cells in the Dog Bone Marrow: Effect of Femoral Artery Clamping During in Vivo Availability of Thymidine-H

Description: Mammalian bone marrow contains a considerable number of small lymphoid cells (small lymphocytes and small lymphocyte-like cells). The total number of these cells (50,000 to 500,000 per mm3) depends on species, age and other factors. The origin, function and fate of these cells remain obscure in many respects. In particular, it has not been shown beyond doubt, if and to what extent small lymphoid cells enter the bone marrow via the blood stream or if their origin is in part or entirely within th… more

Bacterial Virus: Radiation and Function

Description: One of the materials most extensively studied with the dry state ionizing particle approach described in the preceding papers has been T-1 bacteriophage. It was one of the earliest materials subjected to cyclotron bombardment in the Yale biophysics group (Pollard and Forro, 1951) and a number of workers associated with the group have from time to time returned to it (Pollard and Jane Setlow, 1954). One reason is that investigation of various functional properties of a single material is relativ… more

Beam Separators for Bev Particles

Description: The problem of separation of beams of particles of different masses but of the same momentum at Bev energies is the subject of a great deal of study at several high energy laboratories. In this note we shall describe the problem and tabulate a few of the cogent parameters. Frequently the student of high energy interactions is faced with a beam of miscellaneous particles coming from an accelerator. By standard techniques this beam can be rendered approximately parallel and an inch or so in diame… more
