A two-dimensional symmetrical cylindrical transport model for TAP pulse response experiments is analyzed and compared with the one-dimensional TAP model. It is shown that both models give the same total exit flow for experimentally realistic boundary conditions. The uniformity of the flux distribution at the outlet face of the cylindrical model is also analyzed. It is shown that after time greater than t(peak)/60, the flux distribution on the radial coordinate of the outlet face can be considered uniform.
