The first measurements of the nuclear burn region of OMEGA implosions have been made with the Proton Core Imaging Spectroscope (PCIS). Using CR-39 nuclear track detectors, PCIS applies the technique of penumbral imaging to measure the radial profile of D-D and D-3He protons produced by implosions of D2-3He-filled capsules. For capsules with 20 [mu]m-CH shells, images of D-3He protons resulted in Gaussian profiles with an average l/e radius of [approx.]35 [mu]m. Gaussian profiles inferred from the D-3He protons and D-D protons produced by implosions of 2 [mu]tm SiO2-shell capsules had average l/e radii of 60 [mu]m and 94 [mu]m, respectively. [mu]m and 94 [mu]m, respectively.
