Caption courtesy D. Allan Bromley: "A demonstration of the high-precision possible with a gold silicon semiconductor junction detector. This was the spectrum obtained by bombarding a carbon target with a beam of carbon ions showing the elastic scattering from carbon as well as from the silicon and oxygen contaminants in the carbon film target. This particularly [sic] spectrum is unique, as indicated, because it was taken with the world's first tandem accelerator, with the world's first silicon semiconductor nuclear detector, and with the world's first transistorized mult-channel analyzer -- [at Chalk River Nuclear Laboratories] in late 1959."
