Al Bean taking a close-up photo of the top of the SIDE. The CCIG is to the left of the SIDE while the ribbon cable connecting the SIDE to the Central Station (CS) runs out of the field-of-view to the right. The 'fog' is due to a dust smudge which first shows up on 6813. The crater at the lower right is large enough and deep enough to be discernible in LROC images

taken at high solar elevations high enough to show tracks left by the astronauts. The crater is labeled 'a' in the LROC images. Pete Conrad would have taken 6820 while standing just below the 'a'.
Paraphrased from the ALSJ.
The Suprathermal Ion Detector Experiment (SIDE) was designed to measure various properties of positive ions in the Lunar environment, provide data on the plasma interaction between solar wind and the Moon, and to determine the electrical potential of the Lunar surface.
The Cold Cathode Ion Gauge (CCIG) experiment was designed to measure the pressure of the Lunar atmosphere. It was originally designed to be part of the SIDE, but its strong magnetic field would have caused interference.
