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.

Core DIM-based diagnostic DIXI drifts and time dilates a photo-electron image of an implosion. The time dilation allows time resolution to better than 10 ps. This kind of time resolution is necessary because as the yield increases, the duration of x-ray emission reduces to 100 ps.

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).

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 Chamber Center (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

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.

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.

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.

2013年9月26日 · Alignment of an x-ray imager line of sight in the National Ignition Facility (NIF) target chamber using a Diagnostic Instrument Manipulator (DIM) and Opposed Port Alignment System (OPAS)

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 ...
