Abstract Text:
In most plasmas, it is difficult to take measurements at many locations, so it would be useful to be able to use measurements of the distribution function at one location to learn about the distribution function at other locations. We use the G-transform, an integral transform based on the Hilbert transform, to convert the equations of motion for the distribution function into a first order differential equation solvable using the method of characteristics. Integrating the characteristic equations, and then inverting the transformation, transfers information from the location of the measurement to other locations in the plasma. We demonstrate this technique using data from a gyrokinetic code for ion electrostatic oscillations in slab geometry.
