80" Bubble Chamber Expansion System Preliminary Operating Procedures

Description: These procedures are intended to be used for the initial operation of the expansion system and serve as a basis for a more complete and revised form to be written once operating experience has been gained. An attempt has been made to offer a logical and systematic presentation to facilitate operation and maintenance of the system by the operating personnel. Thus, the sequence of valve actuations has been presented in matrix and check list form to minimize errors; this also has the advantage of … more

80" Bubble Chamber Expansion System Summary of Piston Motion Studies

Description: Prior to assembly into the 80" bubble chamber, the expansion system was subjected to a series of tests to check piston dynamics and gain information on the reliability of the various components. Furthermore, the rest provided operating personnel with the opportunity to become familiar with the operation and maintenance of the expansion system. Two separate tests were performed with the apparatus that was located at the north end of the AGS experimental area; one during the week of Oct. 15 and t… more

80" Chamber - Low Energy Beams

Description: One of the major, as well as first, decisions which must be taken on a large chamber is to decide on the direction of the magnetic field, i.e., vertical or horizontal. Either alternative has advantages and disadvantages ad it is the intention of this note to discuss these features.

Analysis and Design Significance of A-11 Flow-Induced Vibration Test, Phases I and III

Description: Comparisons of the experimental data on seal pressure distributions obtained from the A-11 Flow Induced Vibration Test, Phases I and III, with analytical results including porous flow through the unimpregnated inner reflector cylinder for the same operating conditions show generally very good agreement. The principal deviations between analysis and experiment occurs when high pressure ratios exist across the last seal. Additional investigation, both in the relationship used in the analytical … more

Analysis and Design Significance of Nozzle Interface Seal Leakage Test Results

Description: The interface seal between the inner reflector cylinder and the nozzle flange prevents coolant flow from bypassing the reflector system and core and flowing directly from the reflector inlet plenum to the core exit.

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

Biological Effects of Thermal Neutrons and the B10 (n,c) Li7 Reaction

Description: Boron-10 has a high thermal neutron capture cross section (3880 barns). Following neutron capture, the subsequent nuclear disintegration produces an alpha particle and a lithium-7 nucleus with the release of an average of 2.34 MeV for the particle irradiation, and in 93% of the reactions there is also the emission of an 0.48 MeV gamma ray: [equation not transcribed]. The kinetic energy is divided between the lithium-7 nucleus and the alpha particle giving the equal and opposite momentums with a… more

Bubble Chamber Vacuum System

Description: The vacuum system for the bubble chamber must evacuate rapidly a volume of approximately 500 cubic feet and eliminate the outgassing of a surface area of approximately 50,000 square inches. The backstreaming of oil from the diffusion pump must be kept to an absolute minimum to prevent oil films forming on the window. The vacuum system must also provide the protection against liquid nitrogen and hydrogen/leaks to prevent pressure buildup.
