Evolution of the 400 MeV linac design

Description: The basic premises of the conceptual design for the linac upgrade are pursued to establish lengths, gradients, power dissipation, etc., for the 400 MeV linac and matching section. The discussion is limited to accelerating and focusing components. Wherever values depend on the choice of the accelerating structure, the disk-and-washer structure is emphasized; the results are generally relevant to the side coupled cavity choice also.

Contributions to the INTOR workshop

Description: This paper discusses the use of Nb/sub 3/Sn conductors as coils for toroidal fields in thermonuclear reactors. In particular, the mechanical properties are investigated for these conductors as well as substitute materials. 8 refs.

Debunching into a bucket of lower harmonic number

Description: The adiabatic debunching of beam from buckets of higher harmonic number into waiting buckets of lower harmonic number is a critical step in the current scheme of operation for Tev I. The optimum choice of rf system parameters for this ''bunch coalescing'' process is not immediately obvious. In this note two examples are presented along with generalizations based upon them and experience with the Tevatron I design which can simplify the selection of appropriate parameters for different condition… more

Nitrogen oxide abatement by distributed fuel addition

Description: This program is designed to develop techniques for NO{sub x} abatement by distributed fuel addition. It is expected that multiple fuel and air addition in the post flame of a combustion process will increase free radical concentrations which destroy nitrogenous species as they decay toward their equilibrium concentrations. This concept will be investigated under both fuel rich and fuel lean conditions in the reburn zone. This report is a brief description of the proposed experimental plan. Resu… more

Deflection analysis for an SSC (Superconducting Super Collider) dipole magnet with two external supports

Description: SSC dipole magnets are presently supported at five mounting locations coincident with the internal cold mass supports. There is growing interest in reducing the number of external supports from five to two for reasons of simplified installation and alignment and as a cost reduction measure. This reports examines the placement of two external supports required to minimize the deflection of the cold mass assembly.

Summary of ANSYS and Strain Gauge Results for the EC Calorimeter OH and MH Modules

Description: The OH and MH modules of the EC calorimeter consist essentially of metal boxes containing calorimetry plates. These plates can contribute to the module behavior only in compression, with this effect being enhanced if the plates are compressively preloaded against the skin of the box prior to assembly. The finite element method can be applied in the analysis of these modules. Its advantages are: 1. The structural components can be modeled with less simplification than beam theory allows. The ang… more

Teenage Sexual Activity and Childbearing: An Analysis of the Relationships of Behavior to Family and Personal Background

Description: "This report uses the National Survey of Family Growth to examine the effects of a variety of social and economic factors on the likelihood that a teenage girl will be sexually active, will use contraceptives, and will bear a child...The report examines the differences in factors associated with these different behaviors for white and black as well as younger and older teens."
