Summary form only given. We have implemented a wide variety of charged-particle diagnostics on OMEGA, including magnet-based spectrometers (CPS); wedge-range-filter-based spectrometers (WFR); proton core image system (PCIS); proton radiography; and proton temporal diagnostics (PTD). Recent work has resulted in the comprehensive measurements of spatial-, temporal- and spectral- resolved energetic charged particles emanating from various capsule implosions as well as from laser-plasma interactions. Such measurements provide information about fusion yield, ion and electron temperature, fuel and shell areal density, target compression asymmetry, and other physical parameters, and have been combined with other traditional diagnostics to study various aspects of ICF implosion physics, including implosion dynamics and target performance. Many fundamental issues related to high-energy density physics are also studied, including capsule charging due to laser-plasma interactions, and stopping power in high-temperature and high-density plasmas. In addition, recent studies have demonstrated feasibility and potential of a novel magnet-recoil-spectrometer (MRS) for measuring charged particles scattered by fusion neutrons at OMEGA and the NIF.
