Query: Development and construction of MAROON-X   We report on the development and construction of a new fiber-fed,
red-optical, high-precision radial-velocity spectrograph for one of the twin
6.5m Magellan Telescopes in Chile. MAROON-X will be optimized to find and
characterize rocky planets around nearby M dwarfs with an intrinsic per
measurement noise floor below 1 m/s. The instrument is based on a commercial
echelle spectrograph customized for high stability and throughput. A microlens
array based pupil slicer and double scrambler, as well as a rubidium-referenced
etalon comb calibrator will turn this spectrograph into a high-precision
radial-velocity machine. MAROON-X will undergo extensive lab tests in the
second half of 2016.
