Proton core imaging spectroscopy (PCIS) is being used to study the effects of fuel shell mix in implosions of D^3He-filled capsules at OMEGA. Penumbral imaging of fusion products is used to obtain the size and shape of the nuclear burn region. Experimental differences in the D^3He burn region will be explored for varying laser conditions and for different shell types (2 to 3 mm glass and 17, 20, 24 and 27 mm CH). Secondary D^3He proton production profiles from a D_2-filled-capsule implosion will be examined to explore the feasibility of imaging cryogenic implosions. Measured burn profiles will be compared to predictions of clean 1-D simulations and to x-ray images.
