The electron spectrometer from University College London (with RAL and NDRE), part of the SWRI-led Cassini Plasma Spectrometer (CAPS) instrument, saw the rings through 'electron eyes', with electron intensity inversely related to ring particle density. The bottom panel shows CAPS-ELS data with colour scale proportional to number of electrons. The top panel shows a Cassini narrow-angle camera visble image of the ring structure for comparison.
