6.3.2. Diagnostic Instrument Manipulator Performance Capabilities

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).
• Accommodation of loads up to 125 kg with a center of gravity no greater than 1.4 m from the cart rear wheels. Carts and diagnostic assemblies can be no larger than 28.5 cm in diameter.¹³
• Accommodation of diagnostic assemblies up to 285 mm in diameter and up to 3 m beyond the front of the diagnostic cart in length. Accommodates loads up to 125 kg with a center of gravity no greater than 1.4 m from the cart rear wheels.¹⁴
• Angular pointing of ±1° is available at the point of mounting at the chamber wall, and ±3° by moving the rear mount.
• A 100 mm clear aperture along the full axis. A CAD model of each DIM is available for designers to use.

From design through deployment, developing a DIM-based diagnostic or snout typically takes nine months to a year. Details on DIMs and how to design diagnostics to be compatible with operation in DIMs are available in Diagnostic Design Guidance for the National Ignition Facility.¹⁵
