     dual will study the origin and evolution of the elements and explores new frontiers of physics: extreme energies that drive powerful stellar explosions and accelerate particles to macroscopic energies; extreme densities that modify the laws of physics around the most compact objects known; and extreme fields that influence matter in a way that is unknown on earth. the variability of these extreme objects requires continuous all-sky coverage, while detailed study demands an improvement in sensitivity over previous technologies by at least an order of magnitude. the dual payload is composed of an all-sky compton imager (asci), and two optical modules, the laue-lens optic (llo) and the coded-mask optic (cmo). the asci serves dual roles simultaneously, both as an optimal focal-plane sensor for deep observations with the optical modules and as a sensitive true all-sky telescope in its own right for all-sky surveys and monitoring. while the optical modules are located on the main satellite, the all-sky compton imager is situated on a deployable structure at a distance of 30 m from the satellite. this configuration not only permits to maintain the less massive payload at the focal distance, it also greatly reduces the spacecraft-induced detector background, and, above all it provides asci with a continuous all-sky exposure.
