Atlas Transmission Line/Transition Design and Fabrication Status

PDF Version Also Available for Download.

Description

Atlas is a pulsed-power facility under development at Los Alamos National Laboratory to drive high-energy density experiments. Design has been completed for this new generation pulsed-power machine consisting of an azimuthal array of 24, 240-kV Marx modules and transmission lines supplying current to the load region at the machine center. The transmission line consists of a cable header, load protection switch, and tri-plate assembly interfacing to the center transition section. The cable header interface to the Marx module provides a mechanism to remove the Marx module for maintenance without removing other components of the transmission line. The load protection switch ... continued below

Description

Atlas is a pulsed-power facility under development at Los Alamos National Laboratory to drive high-energy density experiments. Design has been completed for this new generation pulsed-power machine consisting of an azimuthal array of 24, 240-kV Marx modules and transmission lines supplying current to the load region at the machine center. The transmission line consists of a cable header, load protection switch, and tri-plate assembly interfacing to the center transition section. The cable header interface to the Marx module provides a mechanism to remove the Marx module for maintenance without removing other components of the transmission line. The load protection switch provides a mechanism for protecting the load during charging of the Marx in the event of a pre-fire condition. The aluminum tri-plate is a low-inductance transmission line carries radial current flow from the Marx energy storage system at the machine periphery toward the load. All transmission line components are oil insulated except the solid-dielectric insulated power flow channel connected directly to the load. The transition region at the machine center consists of several components that enable the radial converging vertical transmission lines to interface to a horizontal disk/conical power flow channel delivering current to the load. The current carrying transition components include the high-voltage and ground conductors interfacing to the tri-plate transmission lines. The tri-plate tank attachment ring interfaces to the tri-plate tanks and the base-plate. The base-plate supports the transition components and interfaces to the center support structure of the machine. The bottom insulator also attaches to the base-plate and to the high-voltage conductor, providing an oil containment seal between the transition and vacuum vessel. Design has been completed for all Atlas components. Some prototype hardware fabrication has been completed and first article hardware is in various stages of completion . The first article is a single line of the machine and includes a Marx module, cable header, load protection switch, tri-plate transmission line, and a dump load for testing. Testing is in progress on some prototype and first article components to verify performance before production begins on critical system components. Production will soon begin for much of the overall system, including the Marx tanks, tri-plate tanks, support structure, some transition components, and the personnel platform. These components will be fabricated and installed while the remaining internal components are being fabricated.
