Design and first performance results of novel robotic optical-relay positioners for the MOSAIC instrument on the ELT.
MUST is a planned 6.5m Stage-V spectroscopic survey telescope targeting 100M+ galaxies and quasars to z~5.5 for large-scale structure cosmology studies.
Thermal qualification tests on 6.2-mm-pitch fiber positioners confirm stable repeatability, backlash, and linearity across -20°C to 30°C with no degradation.
A prototype 15-positioner theta-phi module with 6.2 mm pitch was tested for repeatability, backlash, non-linearity, and tilt, with results compared to Stage-5 telescope design targets.
Performance tests of Trillium-based positioners for Stage-5 telescopes find mostly acceptable metrics with anomalies requiring mitigation in future prototypes.
