3-D electromagnetic modeling of wakefields in accelerator components

Description: We discuss the use of 3-D finite-difference time-domain (FDTD) electromagnetic codes for modeling accelerator components. Computational modeling of cylindrically symmetric structures such as induction accelerator cells has been very successful in predicting the wake potential and wake impedances of these structures, but full 3-D modeling of complex structures has been limited due to substantial computer resources required for a full 3-D model. New massively parallel 3-D time domain electromagne… more

241-BY-106 sampling test plan

Description: This plan outlines the approach to be taken on obtaining the second core from 241-BY-106, riser 10B, using the Rotary Mode Core Sample Truck (RMCST). The purpose for obtaining the second core is to retrieve the final segments to determine ferrocyanide content. The first core acquired from riser 10B resulted in inadequate sample recovery for the labs to perform the required analysis. Thirteen samples were taken, with recovery varying from 0 to 100%. The most likely contributors to poor sample re… more

(The 1990 run of the WA80 experiment)

Description: The traveler spent six weeks at CERN participating in the 1990 run of the WA80 experiment. The traveler concentrated on trigger electronics for the first two weeks and on operation of the experiment for much of the next four. New electronics designed at ORNL for reading out the new BGO spectrometer were tested with the BGO in beam. Improvements were made, in collaboration with the ORNL engineers who designed the electronics. Plans were made for constructing the electronics in large quantities. … more

3D Atlas vertical plate oil transmission line field calculations. Final report

Description: Because of questions regarding current density and inductance estimates of the Atlas oil transmission line in the region where the vertical plates connect to the disk line, calculations using the 3D FE program Flux3d were initiated. Flux3d inductance values are nearly that estimated by D. Scudder. Calculations for three base designs of E. Ballard and D. Pierce were completed where several variations for each base design were used to determine the important parameters affecting inductance and to… more

6430.1A Compliance Matrix for 241-SY-101 Surface Level Rise Remediation Project

Description: Tank 241-SY-101 (SY-101) has recently exhibited a steady waste surface level growth. A path forward to mitigate the SY-101 surface level growth issue has been developed. The project has been directed to install the necessary equipment to transfer 380-570m{sup 3} (100,000-150,000 gallons) of waste from SY-101 to SY-102 before the waste elevation reached the region of the tank where the transition from a double to a single shell tank occurs.

Accelerator production of tritium pollution prevention design assessment

Description: This Pollution Prevention Design Assessment (PPDA) provides data for cost-benefit analysis of the potential environmental impact of the APT, is an integral part of pollution prevention/waste minimization, and is required by DOE for any activity generating radioactive, hazardous, and mixed wastes. It will also better position the APT to meet future requirements, since it is anticipated that regulatory and other requirements will continue to become more restrictive and demanding.
