A close-up view of how the chromosphere might "evaporate" or ablate under electron bombardment. As resolution has improved, the horizontal scale on the cartoon is looking less and less likely. This gives a fair idea of the geometry as envisioned then - compare with the hopeless complexity implied by the more modern De Pontieu cartoon that describes the same "layer" - the chromosphere.
