A Diagnostic Instrument Manipulator (DIM) is provided on three port locations (0-0, 90-315, 90-078) for inserting diagnostics to diagnose a target experiment on NIF. The DIM is a two-stage telescoping system that provides for positioning of the diagnostic package and enables the exchange of diagnostics for different experiments.

A core DIM-based diagnostic GXD records time-resolved images of the target in the x-ray spectral region. GXD uses an array of pinholes to project a series of images onto a detector. Typically, these detectors are located about 1 m from TCC.

NIF DIM-based high-resolution x-ray spectrometer (dHIRES) •!Three crystals are fit in the same plane inside a cassette, covering a large range of x-ray energies •!Detectors are the DISC streak camera and image plate: measure time-resolved and -integrated spectra simultaneously •!dHIRES will be used to measure n e and T

Diagnostic instruments that must be inserted into the target chamber are loaded into a handling device called the diag-nostic instrument mani-pulator (DIM). The DIM features bipod feet (Figure. 2) that have a steering function. The focusing optics inside the NIF chamber are located in a 4-m instru-ment cart called the DIM cart.

NIF diagnostics are either constructed and deployed to a fixed location in the target chamber/target bay or are fielded on a diagnostic instrument manipulator (DIM). DIMs are two-stage telescoping devices capable of inserting, retracting, positioning, and aligning a diagnostic instrument in the Target Chamber, from the interior wall to Target ...

Diagnostic Instrument Manipulator-Related Design Considerations. For a new DIM-based snout, instrument assembly, or instrument attachment to be considered for use at NIF, it must meet several design, safety, and compatibility criteria. The designer must demonstrate that: The design fits into the space envelope.

For instrument design purposes, standard DIM capabilities include: Radial positioning from the wall of the Target Chamber to TCC to a resolution of ±20 mm. Pointing accuracy of ±0.5 mm in both x and y directions (z is along the radial direction of the chamber).

1999年9月14日 · We have done an iteration to identify common diagnostic lines of sight, and with additional requirements defined by specific experiments, we propose (1) a baseline plan for DIM placement requiring only five DIMs that may be moved between up to seven DIM ports, and (2) a modified baseline unconverted light management plan.

2013年9月26日 · 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.
