Field shape measurements of prototype Main Injector dipole endpacks
Measurements of the transverse dependence of the flux on the symmetry plane were obtained on a series of endpacks mounted on a Main Injector prototype dipole. From these flux measurements, we determined the endfield shape, expressed in terms of normal harmonics, up to 14-pole. We describe the measurement and analysis procedure, and present the results for all endpacks that were tested. The final endpack (number 10) has a sextupole, normalized to the body, of +0.167 [plus minus] .072 units, and the relative field shape deviates by [lt] 1.2 units relative to the on-axis field strength over the range [vert bar]x[vert bar] [lt] 2.0[double prime]. These measurements indicate that Endpack 10 meets the requirements for the Main Injector dipole.

Thermo-hydraulic analysis of the TPX superconducting TF magnets
The superconducting magnets in Fusion Reactors are subjected to pulsed, nuclear, and resistive heating. The thermo-hydraulic response of the helium forced-flow cooled conductors to the various heat sources is critical to magnet design and performance. Recently developed computer codes allow accurate modeling of conductor response and have been used as an aid to design of the toroidal field (TF) magnets for the Tokamak Physics eXperiment (TPX). The authors present results of design studies that determine the trade-off between double- and single-pancake helium-flow configurations.

Two-gigawatt burst-mode operation of the intense microwave prototype (IMP) free-electron laser (FEL) for the microwave tokamak experiment (MTX)
The MTX explored the plasma heating effects of 140 GHz microwaves from both Gyrotrons and from the IMP FEL wiggler. The Gyrotron was long pulse length (0.5 seconds maximum) and the FEL produced short-pulse length, high-peak power, single and burst modes of 140 GHZ microwaves. Full-power operations of the IMP FEL wiggler were commenced in April of 1992 and continued into October of 1992. The Experimental Test Accelerator H (ETA-II) provided a 50-nanosecond, 6-MeV, 2--3 kAmp electron beam that was introduced co-linear into the IMP FEL with a 140 GHz Gyrotron master oscillator (MO). The FEL was able to amplify the MO signal from approximately 7 kW to peaks consistently in the range of 1--2 GW. This microwave pulse was transmitted into the MTX and allowed the exploration of the linear and non-linear effects of short pulse, intense power in the MTX plasma. Single pulses were used to explore and gain operating experience in the parameter space of the IMP FEL, and finally evaluate transmission and absorption in the MTX. Single-pulse operations were repeatable. After the MTX was shut down burst-mode operations were successful at 2 kHz. This paper will describe the IMP FEL, Microwave Transmission System to MTX, the …

Assessment of a magnet system combining the advantages of cable-in-conduit forced-flow and pool-boiling magnets
This paper presents an idea for a magnet system that could be used to advantage in tokamaks and other fusion engineering devices. Higher performance designs, specifically newer tokamaks such as those for the international Tokamak Engineering Reactor (ITER) and Tokamak Physics Experiment (TPX) use Cable in Conduit Conductor (CICC) forced flow coils to advantage to meet field and current density requirements. Pool boiling magnets lack structural integrity to resist high magnetic forces since helium cooling areas must surround each conductor. A second problem is that any leak can threaten the voltage standoff integrity of the magnet system. This is because a leak can result in low-pressure helium gas becoming trapped by limited conductance in the magnet bundle and low-pressure helium has poor dielectric strength. The system proposed here is basically a CICC system, with it`s inherent advantages, but bathed in higher pressure supercritical helium to eliminate the leak and voltage break-down problems. Schemes to simplify helium coolant plumbing with the proposed system are discussed. A brief historical review of related magnet systems is included. The advantages and disadvantages of using higher pressure, supercritical helium in combination with solid electrical insulation in a CICC system are discussed. Related electrical data from …

An {Omega}({radical}log log n) lower bound for routing in optical networks
Optical communication is likely to significantly speed up parallel computation because the vast bandwidth of the optical medium can be divided to produce communication networks of very high degree. However, the problem of contention in high-degree networks makes the routing problem in these networks theoretically (and practically) difficult. In this paper we examine Valiant`s h-relation routing problem, which is a fundamental problem in the theory of parallel computing. The h-relation routing problem arises both in the direct implementation of specific parallel algorithms on distributed-memory machines and in the general simulation of shared memory models such as the PRAM on distributed-memory machines. In an h-relation routing problem each processor has up to h messages that it wishes to send to other processors and each processor is the destination of at most h messages. We present a lower bound for routing an h-relation (for any h > 1) on a complete optical network of size -n. Our lower bound applies to any randomized distributed algorithm for this task. Specifically, we show that the expected number of communication steps required to route an arbitrary h-relation is {Omega}(h + {radical}log log n). This is the first known lower bound for this problem which does …

Acid Solution Absorption of Extruded Polyethylene Foam (U)
Water and acid absorption tests of samples of a proposed replacement to current polyethylene foam used as fill material on the FB-Line cation columns have been completed. Water and nitric acid solution absorption of up to 4 volume percent was observed over approximately a 4 month period of time. Because of the nuclear safety implications, liquid absorption of a replacement fill material must be low. EthafoaM{trademark} 220 extruded polyethylene, a product available from Dow Chemical Company appears to be a good candidate material for replacement of the existing fill material. Establishment of 5 volume percent solution absorption specification appears to be both reasonable and achievable for a replacement foam, provided it is acceptable to nuclear safety personnel.

Conference summary
The conference began with an introductory lecture by Bunakov. It is very appropriate that this workshop be held in Dubna as Bunakov reminded us that the experiments that motivated the current interest in the study of symmetry violation with neutrons were started here at Dubna by Alfimenkov, Pikelner, and collaborators. Bunakov discussed the fact that is the complexity of the compound nucleus that leads to large enhancement of parity violation near P-resonances and to the possibility of using statistical models to relate the measured parity violation to more-fundamental quantities. He also pointed out that it is a rare case in which complexity aids us. Bunakov did not point out that this is an example of another rare phenomena -- where theory has predicted correctly in advance the parity violating effects seen near p-resonances. As long ago as 1969, Karmanov and Lobov first predicted an enhancement of {gamma}-ray circular polarization near p-resonances. Sushkov and Flambaum later predicted asymmetries P {approximately} 10{sup {minus}2} for p-resonances and suggested {sup 117}Sn, {sup 139}La, {sup 232}Th, and {sup 238}U for study. Bunakov and Gudkov developed a theory describing the energy dependence of parity-violating effects over a large energy range. This theory predicted random signs for …

Environmental Implementation Plan - EIP introduction
Due to the commitment and participation of more than 100 professionals from site environmental coordinators, customer improvements and total quality are being incorporated into the Environmental Implementation Plan (EIP). The EIP is now a living document that communicates an overview of site environmental programs and the facility plans that are designed to protect the environment and meet changing regulatory requirements. Continuous improvement of environmental programs is enhanced through planned quarterly self-assessments during the {open_quotes}Reflections{close_quotes} process. Through the sharing of noteworthy practices, lessons learned, and ideas for improvement, the EIP provides a framework for environmental professionals to promote cost effective solutions and program improvements through teamwork and communication. These efforts were initiated by the Central Environmental Committee Executive Committee (CECEC) and developed and coordinated by the EIP subcommittee. The EIP revision process is the baseline for a continuous improvement cycle. Although the EIP is a Westinghouse Savannah River Company (WSRC) document, the environmental-planning process involves and will benefit all site contractors. Together, we are committed to a {open_quotes}Partnership in Environmental Excellence.{close_quotes}

Bench-scale testing of the multi-gravity separator in combination with microcel. Fourth quarterly report, July 1, 1993--September 30, 1993
Work this quarter included equipment installation, shakedown testing, and the beginning of the detailed testing program. With the exception of ongoing Task 4: Sample Characterization, Tasks 1 through 8 are now complete. Task 10: Detailed Testing and Task 12: Sample Analysis began this quarter and will consume all available time during the 5th quarter. Installation and testing of the process equipment, mechanical systems, as well as the electrical systems were completed. The shakedown process uncovered several necessary modifications to the circuit which were subsequently completed. Most of the changes concerned piping and valving modifications which allowed for better material flow and sampling. The circuit was operated with coal to determine the time for each unit to reach steady state. The primary objective of the proposed work is to design, install, and operate an advanced fine coal processing circuit combining the Microcel{trademark} and Multi-Gravity-Separator (MGS) technologies. Both of these processes have specific advantages as stand-alone units. For example, the Microcel column effectively removes ash-bearing mineral matter, while the MGS efficiently removes coal-pyrite composites.

Integrated Computer-Enhanced Remote Viewing System. Quarterly report No. 3, April--June 1993
The Interactive, Computer-Enhanced, Remote Viewing System (ICERVS) is designed to provide a reliable geometric description of a robotic task space in a fashion that enables robotic remediation to be carried out more efficiently and economically that with present systems. The key elements are a robust way to store empirical data and a friendly user interface that provides an operator with timely access to all that is known about a scene. ICERVS will help an operator to analyze a scene and generate additional geometric data for automating significant portions of the remediation activity. Features that enable this include the following: storage and display of empirical sensor data; ability to update segments of the geometric description of the task space; side-by-side comparisons of a live TV scene and a computer generated view of the same scene; ability to create and display computer models of perceived objects in the task space, together with textual comments; and easy export of data to robotic world models for robot guidance. Phase 1 of this project was essentially completed in the month of June. Phase 1 (Level III) of this project focuses on the development of the Data Library, which contains the geometric data about the task …

Toward a surface photoelectron diffractometer: A progress report on selected advances and an assessment
X-ray diffractometric determination of atomic structures in ordered bulk systems is highly automated and has wide application. By contrast, surface crystallography, whether based on photon or electron scattering, is still in a relatively early stage of development. A summary is given of recent selected highlights in efforts to make progress toward surface photoelectron diffractometry and holography by our Berkeley-Penn State group. It is concluded that an automated photoelectron diffractometer is practical and desirable.
