A Hybrid R-Theta Fiber Positioning Robot Using a Piezoelectric Bender for Radial Motion
Michael Schubnell, Tim Fanning, Andrew Hope +3
Future massively multiplexed spectroscopic surveys require focal planes with increasingly dense arrays of robotic fiber positioners. The DESI (Dark Energy Spectroscopic Instrument)…
Spec-S5: A Next-Generation All-Sky Spectroscopic Facility Enabling Large-Scale Surveys for Cosmology and Astrophysics
Claire Poppett, David J. Schlegel, Arjun Dey +8
The Stage-5 Spectroscopic Experiment (Spec-S5) is a next-generation, all-sky spectroscopic facility designed to address fundamental questions in cosmology and astrophysics. Buildin…
Linear motion (R-FLEX) for minature 6.2 mm pitch optical fiber position robots with polar (R-theta) kinematics
Nicholas R. Wenner, Joseph H. Silber, Michael S. Schubnell +4
R-FLEX is a compact, low-part-count flexure-based radial positioning mechanism designed for the next generation of massively parallel fiber-fed spectroscopic telescope instruments.…
Design and performance of "R-FLEX", a flexure-based fiber positioning robot for spectroscopic cosmology
Nicholas R. Wenner, Joseph H. Silber, David J. Schlegel
We present the design, fabrication, and testing of R-FLEX, a novel flexure mechanism for next-generation fiber-fed astronomical instruments. As the current Dark Energy Spectroscopi…
The Spectroscopic Stage-5 Experiment
Robert Besuner, Arjun Dey, Alex Drlica-Wagner +106
The existence, properties, and dynamics of the dark sectors of our universe pose fundamental challenges to our current model of physics, and large-scale astronomical surveys may be…
