Paper
HEX-P is a probe-class mission concept that combines the power of high angular resolution with broad bandpass coverage to provide the necessary leap in capabilities to address the important astrophysical questions of the next decade. HEX-P achieves its breakthrough performance by combining technologies developed by experienced partners and international collaborations. HEX-P will be launched into L1 for a high observing efficiency, and to meet the science goals the payload consists of a suite of three co-aligned X-ray telescopes designed to cover the 0.2 - 80 keV bandpass where accretion is at its peak. The High Energy Telescope (HET) has an effective bandpass of 2-80 keV, and the Low Energy Telescope (LET) an effective bandpass of 0.2-20 keV. The combination of bandpass and high observing efficiency delivers a powerful General Observer platform for a broad science that services a wide community base. The baseline mission is 5 years, with 30% of t
