REMOTE OPERATIONS IN A GLOBAL ACCELERATOR NETWORK.

Description: The INTRODUCTION to this paper summarizes the history of the Global Accelerator Network (GAN) concept and the recent workshops that discussed the relationship between GAN and Remote Operations. The REMOTE OPERATIONS SCENARIOS section brings out the organizational philosophy embodied in GAN-like and to non-GAN-like scenarios. The set of major TOPICS RAISED AT THE WORKSHOPS are only partially resolved. COLLABORATION TOOLS are described and discussed, followed by examples of REMOTE ACCELERATOR CONTROL PROJECTS around the world.

Remote Manipulation for D&D Exhibiting Teleautonomy and Telecollaboration

Description: The purpose of the work is to enhance remote operations of robotic systems for D&D tasks by extending teleoperation with semi-autonomous functions. The work leverages the $1.2M dual-arm work platform (DAWP) developed with broad participation for the CP5 D&D, as well as 2,000 hr DAWP D&D operational experience. We propose to develop a reactive, agent-based control architecture well suited to unstructured and unpredictable environments, and robot control technology, which implements a virtual fixture that can be used to guide the application of tools with force-feedback control. Developed methodologies will be implemented using a structured light sensor and robot hand controller on the dual-arm system.

Remote Manipulation of D&D Exhibiting Tele-Autonomy and Tele-Collaboration

Description: Teleoperation has found much application in today's society. While its benefits make it advantageous in many situations, teleoperation also introduces new challenges. In this paper, we present techniques to improve teleoperation performance by making better use of the human's inherent skills.

D. R. Dolly Instruction Book

Description: Instruction book for the DR Dolly. "The DR Dolly is a unit which is designed to perform various mechanical operations which a man would otherwise perform if he were able to work safely in the area where the Dolly is to operate. It consists of six mechanical components mounted on a steel car which in turn runs back and forth on rails. The car simply forms a movable platform for the following components, which are: a 36" mirror, a mechanical arm and various hands, two valve turners, a ram, and a nozzle remover."

Operator Manual for X-ray Residual Stress Mapping

Description: This document is intended to serve as a operator manual for remote control of the TEC x-ray diffraction system. It is assumed that the reader is familiar with the operation of the SaraTEC{trademark} 1630 Acquisition Manager software for the TEC 1630 X-Ray Diffraction System. This manual describes the operation of the new TEC Remote Serial Control Module (RCSM) that runs on the TEC computer and Run-the-System that runs on the motion control computer. The basic goal is to add enough control of the TEC system to enable stress mapping. In stress mapping, the specimen is positioned using our X-Y-Z-Phi translation system and data is collected using the TEC system. The process is then repeated for the next position using a table of preset positions. X-Y-Z-Phi axis management is handled by ''Run-the-System'', the LabVIEW program originally developed for the Neutron Residual Stress Mapping Facility, running on a separate computer from the one that controls the TEC. Run-the-System also manages all remote start, stop, and configuration commands that are sent to the TEC system. The two computers communicate over an RS-232 serial line.

REMOTELY RECHARGEABLE EPD

Description: Radiation measurements inside the Contact Decon Maintenance Cell (CDMC) in the Defense Waste Processing Facility (DWPF) at the Savannah River Site (SRS) are required to determine stay times for personnel. A system to remotely recharge the transmitter of an Electronic Personnel Dosimeter (EPD) and bail assembly to transport the EPD within the CDMC was developed by the Savannah River National Laboratory (SRNL) to address this need.

A STUDY OF THE TENSILE FRACTURE AND MICROSTRUCTURE OF URANIUM

Description: Tensile tests and exhaustive metallographic examinations were conducted in an effort to relate the mechanical proper ties, the chemical compositions, and the structures of five grades of Savannah River Laboratory uranium to their irradiation stability. Subsequent tensile tests were conducted on seven types of National Lead (Ohio) uranium containing various levels of iron, aluminum, and silicon. Special attention was devoted to the mode of fracture exhibited by the various materials and to the existence of grain-boundary phases and intergranular fracture. No evidence was noted of grain-boundary failure at temperatures up to 450 deg C. Most or all failures were precipitated by secondary phases not associated with the grain boundaries. No definite connection was noted between the chemical composition and the tensile properties of the materials that could be related to their irradiation stability. A supplementary study concerned with the substructure and fine-particle distribution in cast uranium was also undertaken. The major accomplishment of this study was the development of metallographic techniques. Particularly interesting were the microstructures revealed by vacuum-cathodic etching. (auth)

Scaling Up: Kilolumen Solid-State Lighting Exceeding 100 LPW via Remote Phosphor

Description: This thirty-month project was successful in attaining its ambitious objectives of demonstrating a radically novel 'remote-phosphor' LED light source that can out-perform conventional conformal coated phosphor LED sources. Numerous technical challenges were met with innovative techniques and optical configurations. This product development program for a new generation of solid-state light sources has attained unprecedented luminosity (over 1 kilo-lumen) and efficacy (based on the criterion lumens per 100mw radiant blue). LPI has successfully demonstrated its proprietary technology for optical synthesis of large uniform sources out of the light output of an array of separated LEDs. Numerous multiple blue LEDs illuminate single a phosphor patch. By separating the LEDs from the phosphor, the phosphor and LEDs operate cooler and with higher efficiency over a wide range of operating conditions (from startup to steady state). Other benefits of the system include: better source uniformity, more types of phosphor can be used (chemical interaction and high temperatures are no longer an issue), and the phosphor can be made up from a pre-manufactured sheet (thereby lowering cost and complexity of phosphor deposition). Several laboratory prototypes were built and operated at the expected high performance level. The project fully explored two types of remote phosphor system: transmissive and reflective. The first was found to be well suited for a replacement for A19 type incandescent bulbs, as it was able to replicate the beam pattern of a traditional filament bulb. The second type has the advantages that it is pre-collimate source that has an adjustable color temperature. The project was divided in two phases: Phase I explored a transmissive design and Phase II of the project developed reflective architectures. Additionally, in Phase II the design of a spherical emitting transmissive remote phosphor bulb was developed that is suitable for replacement of A19 and similar light bulbs. In ...

Report for General Research April 1 to July 26, 1950 (Actinium Volume)

Description: The present phase of the actinium program involves selecting a process and designing the necessary facilities to separate the actinium from five-gram batches of irradiated radium. This installation will serve as a pilot plant for future work and will provide a source of appreciable quantities of actinium. In the selection of a process we are relying to a great extent on the work done by F. T. Bagemaun at Argonne National Laboratory. Our facilities and equipment, for the most part, will be either developments of the Remote Control Division of Argonne National Laboratory or modifications of their work.

Description: being developed, which will make it possible to transmit information from 100 or more in-core sensors through a single pressure vessel penetration. The development of a multiplexing subsystem for use within the reactor pressure vessel is being carried out. The most promising methods of multiplexing investigated are electromechanical commutation and electroric frequency division. (M.C.G.)
