FIG. 1.

Diagram illustrating the elements of a typical neutron aperture imaging system, including recording via charge coupled device camera. To measure spatially resolved ion temperature the recording system must allow for temporally resolved recording.

Image of FIG. 2.
FIG. 2.

An illustration of how a cylindrical lens may be used to produce one-dimensional projections of the fluor light. The lens is focused on to ribbons of optical fiber which are coupled to the input of a streak camera. The vertical line drawn through the fluor image indicates the line integral performed by a fiber within the projection projection.

FIG. 3.

The tomographic streak recording of fluor light produced by neutrons from shot 40348 at the Omega laser, LLE, University of Rochester, Rochester, NY. Four projections, oriented 45° relative to each other were recorded using 40 fibers per projection. Timing fiducials are spaced at intervals.

Image of FIG. 4.
FIG. 4.

Qualitative performance comparison of the MENT image calculations, without noise, by varying the number projections, 4, 5, and 8. The panel labeled “Original” was used as the test object to be reconstructed.

FIG. 5.

Images calculated from an imaging test using the SPHINX x-ray source at Sandia National Laboratory, Albuquerque, NM. See text for details.
