Establishment and maintenance of a coal sample bank and data base

Description: Data from both instruments indicate that atmospheric oxygen is leaking into the primary and secondary containers. The methods and containers tested cannot maintain an inert atmosphere over the long term. The actual percentage of oxygen in the containers is thought to be influenced by several factors: (1) Flushing with argon by any method only displaces part (50 to 80%) of the atmospheric air present in the container after it is filled with coal. Because the atmosphere may not be homogeneous, an… more

Influence of extrinsic crack deflection and delamination mechanisms on the cryogenic toughness of aluminum-lithium alloy 2090: Behavior in plate (T81) vs sheet (T83) material

Description: Cryogenic strength-toughness relationships are examined in 1.6-mm- thick sheet of commercial 2090-T8 aluminum-lithium alloy, and results compared with behavior in 12.7-mm-thick rolled plate. Unlike the significant increase in L-T fracture toughness exhibited by thick place sections at cryogenic temperatures, the thin sheet (of normally similar composition and microstructure) shows a marked decrease in toughness between 298 and 77 K. Such contrasting observations are attributed primarily to the … more

An alternate end design for SSC dipoles

Description: Experience in the SSC dipole program has shown that fabrication of cylindrical coil ends is difficult. Cable stiffness requires large forces to maintain the proper position of the conductors in the end during winding. After winding, the coil ends remain distorted nd significant motion of the need conductors is required to force the coil end into the molding cavity. Local mechanical stresses are high during this process and extra pieces of insulation are required to prevent turn-to-turn shorts f… more

Low energy p p physics

Description: A detailed investigation of proton-antiproton interactions at low energy has become feasible with the commissioning of the LEAR facility in 1983. We shall shortly review the status of {bar p}p annihilation at rest and the physics motivations for second generation experiments with the Crystal Barrel detector. This type of detector would be adequate for the study of both Kp and {bar p}p interactions on an extracted beam of the KAON Factory. We shall conclude with a few remarks on the physics oppo… more

Rotationally Sampled Wind Characteristics for Several Rotor Sizes Using Laser Anemometer Measurements

Description: The concept of measuring the wind velocity rotationally around crosswind circles using a circle-scanning Doppler laser anemometer is investigated to determine the technique's suitability as an effective, simple, economical, and nonintrusive method for estimation turbulence at a wind turbine rotor. Estimates of wind features obtained using the lidar technique are compared to actual wind measurements obtained using a vertical plane array of anemometers, and to other estimates generated using… more

Rollfix---An adiabatic roll transition for the SLC (Stanford Linear Collider) Arcs

Description: The SLC Arcs were rolled at achromat boundaries to follow the terrain of the SLAC site. This makes the linear optics sensitive to systematic gradient errors, from which severe cross-plane coupling effects may arise. As a partial correction, a smoother roll transition was introduced which relieves much of this sensitivity. We present an evaluation of this scheme and report on the observed improvements. 18 refs., 10 figs.

Fire testing and analysis of TRUPACT-I Thermal Test Article

Description: This report documents the fabrication and thermal test of a full-scale prototype of the revised TRUPACT-I design. The fire test demonstrated that the response of the Test Article to a jet-fueled pool fire, subsequent to the impact and puncture tests, meets the impact, puncture, and thermal performance requirements of the regulations governing transport of radioactive materials. The Test Article was a replica of the front half (closure end) of the revised TRUPACT-I design. To simulate the cumula… more

Transverse energy and multiplicity from heavy ion collisions at 200 A GeV

Description: The successful acceleration of light ions at the CERN SPS and at the Brookhaven AGS opened the exciting field of ultra-relativistic heavy ion collisions for systematic studies. The first experiments were designed mainly to survey the reactions and to establish the essential features of the collisions. In this paper results from the WA80 experiment on transverse energy and charged particle multiplicity are reported. These two quantities are determined by most of the experiments and can be used t… more

Development of superconducting strand and cable with improved properties for use in SSC (Superconducting Super Collider) magnets

Description: The critical current requirement for the NbTi superconductor strand was set at 2750 A/mm/sup 2/ (5 T, 4.2 K) in the SSC Conceptual Design, compared with a value of 1800 A/mm/sup 2/ which was specified for the strand used in the Tevatron dipoles. In addition, a filament diameter of 5 ..mu..m, instead of the 9 ..mu..m diameter used in the Tevatron, was chosen to reduce field distortion at injection. In order to meet the requirements for field homogeneity, the dimensional requirements for both str… more

Strangeness production in nucleus-nucleus collisions: Experimental summary

Description: Rather than attempt to give a complete review of strangeness production in all kinds of experiments, I will dwell on the most interesting and promising aspects of the experimental results from nucleus-nucleus (A + A) experiments, using p + p//bar p/ + p and p + A//bar p/ + A data only as reference when needed. In this paper I will try: to identify the important features of the reaction mechanism; to understand the mechanisms; to learn about quark-gluon plasma formation by comparing nucleus-nucl… more

UMTRA Project environmental, health, and safety plan

Description: The basic health and safety requirements established in this plan are designed to provide guidelines to be applied at all Uranium Mill Tailings Remedial Action (UMTRA) Project sites. Specific restrictions are given where necessary. However, an attempt has been made to provide guidelines which are generic in nature, and will allow for evaluation of site-specific conditions. Health and safety personnel are expected to exercise professional judgment when interpreting these guidelines to ensure the… more

A CP violation and rare kaon decay experiment at Fermilab

Description: The E731 collaboration at Fermilab has collected enough K ..-->.. 2..pi.. events to give a statistical error of approx.0.5 /times/ 10/sup /minus/3/ on the CP violation parameter epsilon'/epsilon. Improvements have been made to reduce the systematic error. The experiment is also sensitive to many rare decays, and it set a new limit on the branching ratio of K/sub L/ ..-->.. ..pi../sup 0/e/sup +/e/sup /minus//, < 4.2 /times/ 10/sup /minus/8/ (90% CL). 10 refs., 15 figs., 1 tab.
