STROBE-X High Energy Modular Array (HEMA)

Abstract: The High Energy Modular Array (HEMA) is one of three instruments that compose the STROBE-X mission concept. The HEMA is a large-area, high-throughput non-imaging pointed instrument based on the Large Area Detector developed as part of the LOFT mission concept. It is designed for spectral timing measurements of a broad range of sources and provides a transformative increase in sensitivity to X-rays in the energy range of 2--30 keV compared to previous instruments, with an effective area of 3.4 m$<sup>{2}$ at 8.5 keV and an energy resolution of better than 300 eV at 6 keV in its nominal field of regard.
