Abstract

The Low Energy Modular Array (LEMA) is one of three instruments that compose the STROBE-X mission concept. The LEMA is a large effective-area, high throughput, non-imaging pointed instrument based on the X-ray Timing Instrument of the Neutron star Interior Composition Explorer (NICER) mission. The LEMA is designed for spectral-timing measurements of a variety of celestial X-ray sources, providing a transformative increase in sensitivity to photons in the 0.2-12 keV energy range compared to past missions, with an effective area (at 1.5 keV) of 16,000 cm $^2$ and an energy resolution of 85 eV at 1 keV.
