Measurements of magnetic field alignment (open access)

Measurements of magnetic field alignment

The procedure for installing Superconducting Super Collider (SSC) dipoles in their respective cryostats involves aligning the average direction of their field with the vertical to an accuracy of 0.5 mrad. The equipment developed for carrying on these measurements is described and the measurements performed on the first few prototypes SSC magnets are presented. The field angle as a function of position in these 16.6 m long magnets is a characteristic of the individual magnet with possible feedback information to its manufacturing procedure. A comparison of this vertical alignment characteristic with a magnetic field intensity (by NMR) characteristic for one of the prototypes is also presented. 5 refs., 7 figs.

Analytical cytology applied to detection of induced cytogenetic abnormalities (open access)

Analytical cytology applied to detection of induced cytogenetic abnormalities

Radiation-induced biological damage results in formation of a broad spectrum of cytogenetic changes such as translocations, dicentrics, ring chromosomes, and acentric fragments. A battery of analytical cytologic techniques are now emerging that promise to significantly improve the precision and ease with which these radiation induced cytogenetic changes can be quantified. This report summarizes techniques to facilitate analysis of the frequency of occurrence of structural and numerical aberrations in control and irradiated human cells. 14 refs., 2 figs.

Neutronics issues for a laboratory microfusion facility (open access)

Neutronics issues for a laboratory microfusion facility

Discussion concerning goals or design of the Laboratory Microfusion Facility (LMF) should include an understanding of the neutronics issues involved. We consider such aspects as first wall shielding requirements, safety standards as they will apply to such an Inertial Confinement Fusion (ICF) facility, and the interior chamber environment. The selection of materials for the first wall, neutron moderator and absorber, and gamma ray shielding is discussed. We conclude that water or carbon are the choices for bulk neutron moderation and boron placed just in front of the first wall the choice for neutron absorber. Selection of the in-chamber materials and diagnostic design will greatly affect the relative hazards after a shot. Lead is the high-Z material of choice and plastic expendables for the diagnostics. Although a poor gamma ray attenuator, carbon is the choice for this function since it also compensates for the direct neutron shine effects and does not itself activate. Electronics may need to be hardened to the prompt gamma and neutron dose.

The Mobile Intercontinental Ballistic Missile (MICBM) simulation (open access)

The Mobile Intercontinental Ballistic Missile (MICBM) simulation

The purpose of this project was to investigate the capability of blending traditional discrete event simulation techniques with artificial intelligence technology. In order to fully demonstrate the capabilities of such a simulation environment, a difficult class of simulation problem was selected for the project: a military C/sup 3/ (command, control, and communication) simulation. The hardware chosen for the project was a Symbolics LISP machine running an artificial intelligence shell called Knowledge Engineering Environment (KEE). This environment provided a powerful simulation capability in which human decision-making processes could be readily represented.

Elements of a system for verifying a Comprehensive Test Ban (open access)

Elements of a system for verifying a Comprehensive Test Ban

The paper discusses the goals of a monitoring system for a CTB, its functions, the challenges to verification, discrimination techniques, and some recent developments. It is concluded technical, military and political efforts are required to establish and verify test ban treaties which will contribute to stability in the long term. It currently appears there will be a significant number of unidentified events. (ACR)
