Paper Abstract

The Diagnostic Instrument Manipulators (DIMs) are two-staged, telescoping systems that allow the precise alignment and positioning of various x-ray, optical, nuclear, and other diagnostics in the National Ignition Facility (NIF) Target Chamber. Designed to be reconfigurable and exchangeable between NIF experiments, the second stage of the DIM is referred to as the Diagnostic Load Package (DLP), which is most often comprised of a cart, diagnostic, and detachable snout. As experiments continue to increase radiation levels, various upgrades have been made to the DIMs to improve reliability and operational efficiency. These upgrades reduce worker exposure and increase experimental shot rates. Specific to this paper, the design and operation of dedicated DLP handling and storage units (DHUs and DSUs) are discussed in addition to their transport equipment. Hardware and process improvements for reduced worker exposure during general DIM access are also featured. Finally, the DLP limit switches have been upgraded to magneticallyactuated proximity sensors for reliability, improved shot rate, and increased user flexibility.
