[en] Some recent work has been done to look at improvements of transporting beam from the Lithium Lens to the Debuncher. This work has been done using the beamline modeling tools developed by Dave McGinnis. These tools, console application P143 and optimization code running MAD repeatedly on the Beam Physics UNIX system, were first used to match the Twiss and dispersion parameters at the end of AP2 to the Debuncher. Imaginary trims were then added to AP2 to study where additional trims could be used to help with beam control in small aperture areas.
[en] A new Main Control Room (MCR) has been built to control the accelerators of the AGS Complex. A new physical environment was produced to better control light, sound, temperature, and traffic. New control consoles were built around the work-stations that make up the distributed control system. Equipment placement within consoles and console placement within the room reflect attention to the ''human factors'' needs of the operator. 1 ref., 2 figs
[en] A best matching algorithm was found using a test program written in Mathematica, and was integrated into an accelerator control on-line program. This on-line program now gets rid of network communication, and does not need to run code MAD. In this report, we first describe the matching conditions, and 4 cases of constrains. Using a test program written in Mathematic, given a change of tunes, we were able to find the possible combination of the quadrupole strength in trombone section for each case. We then tested the calculation results by simulations using code MAD and by experiments on the Recycler ring. Finally we found the best matching algorithm and integrated it into an accelerator control on-line program. The test results for the setting and measured tune values by running on-line program on console are also presented
[en] Human factors engineering is an interdisciplinary specialty concerned with influencing the design of equipment systems, facilities, and operation environments to promote safe, efficient, and reliable operator performance. The Electric Power Research Institute (EPRI) has undertaken three projects studying the application of human factors engineering principles to the development of nuclear power plant control rooms
[en] The operator interface of the PS control system consists of 7 large general purpose consoles in the Main Control Room with, in addition, 2 other ones, more compact, fully software compatible and mobile, near clusters of process equipment. The paper describes the consoles and discusses the major design options and their impact
[en] A modular design of an Instructor's Console for a real-time operator training simulator is presented in this paper. The particular design addresses a console that was implemented in phases. The console was developed in a simulation environment that supports multiprocessing. The design and subsequent implementation is discussed
[en] The P2 console application (Antiproton Source RF Files) calculates frequency and voltage curves from a sequence of command statements input by the user. P2 initially calculates these curves in terms of the actual frequencies and voltages required on the RF cavity as a function of time. These curves are then converted to the appropriate low-level drive voltages that will cause the RF system high-level electronics to generate the required frequency and voltage ramps. The low-level drive ramps are then downloaded into CAMAC ramp cards. In order to convert the required cavity voltage and frequency into the correct drive voltages P2 uses a set of constants that determined from calibration measurements of the various Antiproton Source RF systems. These constants are editable from the P2 constants window. The P2 constants at the time of this writing are shown in Figure 1. The validity of these constants determines the extent to which P2 able to translate the user's commands into the actual voltages and frequencies that appear on the RF cavity. A comparison of the 4/18/2001 calibration of ARF1 with that presently assumed by P2 shows a large discrepancy in both the frequency constants and the voltage constants. This report documents the determination of the P2 ARF1 constants from the calibration measurements that were made on April 18, 2001. In addition, this report will compare the measured response of ARF1 to that derived from the present P2 constants. This comparison will be used to explain some resent observations of ARF1 behavior.
[en] The outline of the LOFT Augmented Operator Capability Program is presented. This program utilizes the LOFT (Loss-of-Fluid Test) reactor facility which is located at the Idaho National Engineering Laboratory and the LOFT operational transient experiment series as a test bed for methods of enhancing the reactor operator's capability for safer operation. The design of an Operational Diagnotics and Display System is presented which was backfit to the existing data acquisition computers. Basic color-graphic displays of the process schematic and trend type are presented. In addition, displays were developed and are presented which represent safety state vector information. A task analysis method was applied to LOFT reactor operating procedures to test its usefulness in defining the operator's information needs and workload
[en] Telerobotic development efforts at Oak Ridge National Laboratory are extensive and relatively diverse. Current efforts include development of a prototype space telerobot system for the NASA Langley Research Center and development and large-scale demonstration of nuclear fuel cycle teleoperators in the Consolidated Fuel Reprocessing Program. This paper presents an overview of the efforts in these major programs. 10 refs., 8 figs
