Paper Abstract

The Maunakea Spectroscopic Explorer (MSE) will obtain millions of optical to near-infrared spectra, at low (R~2,500) to high (R~40,000) spectral resolution, via a highly multiplexed (~3000) fiber-fed system. Key science programs for MSE (black hole reverberation mapping, stellar population analysis at high redshift, subkm/ s velocity accuracy for stellar astrophysics) will target faint Galactic and extra-galactic targets (typical visual magnitudes up to 24). MSE will thus need to achieve the highest throughput possible over the 360 to 1800 nm wavelength range. Here we discuss building an optimized throughput budget in terms of performance allocation and technical solutions to steer the concept design studies.
