Objective: To measure spatial structures in plasma using tomographic reconstruction methods. The know-how came from the Naval Research Laboratorys long history of leadership in this field and Dr. Selchers PhD dissertation on ionospheric structures reconstructed from total-electron-content data obtained from beacon-satellite transmitter to ground-receiver phase shifts.
Significance: Superior to single-path information provided by a single sensor, two- and three-dimensional reconstruction of density structures in plasma helps the understanding of the plasma equilibrium and dynamics and the interpretation of the plasma properties from other diagnostics.
Long Range Goal: To detect earthquakes in advance, to detect signatures of nuclear explosions in the immediate past, and to detect volumetric structures in high-density laboratory plasma.
