Scientific paper

The technological approach and scientific promise of the ALEXIS (Array of Low-Energy X-ray Imaging Sensors) experiment is summarized. The optical design, including the imaging characteristics and the expected layered synthetic multistructure performance, is considered. The curved-surface microchannel plate detectors and the ultrasoft X-ray background sources and how they can be overcome are addressed. The high dynamic range electronics needed to detect both ultrasoft X-rays and bursts of ultrasoft X-rays and the onboard hardware and software needed to calculate telescope event positions and the downstream handling of these data are discussed. The overall experiment envelope and the interface with the minisat are examined. The ground support hardware and software and ALEXIS's scientific objectives and sensitivity are addressed.
