[en] The MkV magnetron source has been designed with the goal to achieve an H-or D-yield of 1-2 A in pulses longer than 5 a up to a steady state mode of operation. All electrodes are water cooled and this allows power densities up to 200 W/cm². The source has been operated in hydrogen and hydrogen-cesium modes. Various methods of cesium vapor injection have been tried and their reliability compared. The extractor grid in its first version has been made out of solid molybdenum, without cooling, and operated in a pulsed mode (pulse length more than 1 s)

[en] The Tandem Mirror Experiment-Upgrade (TMX-U) is a new experiment in tandem micrror physics. It uses some of the components of the first Tandem Mirror Experiment (TMX), which was shut down in October, 1980 after successfully operating for more than one year. TMX-Upgrade incorporates additional electrostatic plugging due to electron thermal barriers and microwave heating. This paper is an overview of the TMX Upgrade design and construction

[en] A steady state current drive concept applicable to reversed field pinch (RFP) discharges is presented. The concept, initially proposed by M. Bevir and J. Gray of the Culham Laboratory, entails driving the RFP's toroidal and poloidal magnetic field circuits with low-frequency oscillating voltage sources. The steady state drive concept was examined with a O-D plasma-circuit simulation code presently employed to model the Los Alamos ZT-40 RFP experiment. Simulations indicate the drive concept is feasible provided its perturbative effect on plasma equilibrium, stability, and transport is minimal A summary of these results, along with their implications on present and future RFP devices, is discussed

[en] In anticipation of the appearance of more advanced tokamaks and other fusion relevant experiments, program has been established at ORNL to systemically identify the requirements of an effective machine operations group. This program is presently applied to the ISX-B experiment. With its continuing development, it is expected to provide major support in the identification of potential problem areas and to assist in the generation of the necessary procedures for forthcoming devices. The present and future generations of large plasma devices will function as facilities, operated by an operations group as service to the plasma physicists and diagnosticians. The purpose of the program discussed here is to develop and to encourage an orderly transition to the facility-like style of operation

[en] This paper presents the engineering and design aspects of the TFTR-Vacuum Vessel Cooling Systems (the Shell System and the Bellows System) and the bakeout System. The fabrication of the systems is presently under construction at Chicago Bridge and Iron, Greenville, PA. A previous described the preliminary fluid (dry air and nitrogen) systems used to cool and heat the Vacuum Vessel. This paper updates the previous one. The emphasis is on the engineering approach, evaluation and design related to the three major operational scenarios of the TFTR, namely - Normal Operation, Discharge Cleaning and Bakeout. This paper presents the cooling and heating loads, the flow distribution, one-dimensional temperature distribution evaluation, poloidally and toroidally, a bakeout scenario and the corresponding design solutions, such as the heating/coolilng jacket, diagnostic covers with remote jumper lines, access plates and adjustable orifices in order to balance the flow

[en] New Computer Programs for more accurate estimation of rates of material loss from inertial fusion reactor cavity surfaces have been exercised to determine economic cavity sizes for commercial-applications pellet desings. Large loss rates can contribute subtantially to maintenance and total production costs. Modern Theory, with empirical factors to force agreement with limited experimental data, is used to estimate sputtering loss rates. A computer code, HOTWALL, that treats temperature-dependent physical properties, thermal transport of deposited energy, and arbitrary energy distributions and histories estimates evaporate loss rates

[en] This conference proceedings contains 576 papers, of which 37 appear in abstract form only. Technical coverage is very broad, and concerns topics on plasma engineering, diagnostics, superconductor developments, reactor design, laser applications, computer applications, and future reactor systems. Controls, instrumentation, and data handling were also reviewed at length. 547 papers have been separately abstracted
