Design charts for spacing of vacuum line supports

Description: This paper presents design tables and graphs to aid engineers and designers in the selection of support spacing for vacuum beam lines and other vacuum pipes. This data applies to support spacing for thin wall pipes and tubes under an internal vacuum (or open to atmosphere) and subject to external atmospheric pressure. Data is generated from the equations for a simply supported thin walled pipe or tube of circular cross section. These tables and graphs indicate what the minimum spacing of suppor… more

VTI: VME/CIPRICO Interface routines

Description: This document details the VME/CIPRICO Interface routines (VII). These routines where designed to allow programs written in PILS running on a MVME 101 under Valet-plus to control a CIPRICO tape controller. The routines fall into two general types. The low level routines, such as vti-make-pb, create the data structures used by the CIPRICO as well as manipulate the CIPRICO's control registers. The high level routines, such as vti-rewind, use the lower level routines to carry out complete functions… more

The separation and characterization of a hydrogen getter product mixture: Part 2, measurement of product vapor pressures

Description: HCPB is the acronym of an organic hydrogen getter compound used in weapon systems. When this material scavenges hydrogen by reacting with it, a number of compounds are formed, each of which is more volatile than HCPB. It is desirable to know the vapor pressure of these products in order to assess their migration potential within the weapon. In this study, individual compounds from a reacted HCPB mixture were isolated and their vapor pressures were measured. Three of the four fractions examined … more

Flexible Support Test Procedure and Results

Description: Upon completion of the fabrication process, the four central calorimeter cryostat flexible support assemblies were sent to Construction Technology Laboratories (CTL) in Skokie, IL, where the required tests were performed for Richmond Lox prior to the installation of the stanchions in the cryostat. These tests were to simulate the simultaneous axial and transverse loading experienced by the stanchions when the cryostat undergoes the cool down process.

RTV 21 Displacements

Description: A seal is needed for the cover of the Nitrogen Test Vessel in order to prevent leakage of the N{sub 2} gas. This seal is to be molded out of RTV 21. In this experiment, the Modulus of Elasticity of the RTV was sought after, and the displacements of the RTV due to various stresses were measured to see if they were large enough to provide a tight seal between the vessel and its cover.

OCH Spacer Design

Description: The purpose of the OCH module spacers is to keep the given dimension of .224-inch between the 1.83-inch absorber plates. This distance is determined by two liquid argon gaps of .09-inch each and a readout board of .044-inch. The spacer should be made out of a material that would give a minimum thermal contraction movement. Also the dimension of the spacer will be determined dependent upon the load applied to the spacers and the strength of the material chosen. Considering both thermal contracti… more

Cryogenic Design of the D0 Liquid Argon Collider Calorimeter

Description: The superconducting Tevatron was added to Fermilab's 400 Gev Proton Accelerator, the main ring, in 1983. An antiproton source was added in 1985, and the system became a p-pbar, 1 Tev/I Tev, collider in 1987. A CoIIider Detector surrounding one of the points of the accelerator p-pbar beam crossings can measure virtually all the energy of the colliding interaction (Fig. I.) The measurement of all the energy is called hermetic calorimetry. Although there are other liquid argon calorimeters and oth… more

Summary report of first and foreign high-level waste repository concepts; Technical report, working draft 001

Description: Reference repository concepts designs adopted by domestic and foreign waste disposal programs are reviewed. Designs fall into three basic categories: deep borehole from the surface; disposal in boreholes drilled from underground excavations; and disposal in horizontal tunnels or drifts. The repository concepts developed in Sweden, Switzerland, Finland, Canada, France, Japan, United Kingdom, Belgium, Italy, Holland, Denmark, West Germany and the United States are described. 140 refs., 315 figs.,… more
