title = "Performance of the first production-ready actuators for the 4MOST-AESOP fiber positioner",
abstract = "In this paper we present recent progress on the Australian Astronomical Observatory's AESOP2 fiber positioner for 4MOST (on VISTA). As an evolution of the Echidna {"}spine{"} technology used for FMOS (on Subaru), AESOP has challenging requirements to position 2,448 fibers in parallel, within 1 minute, to an accuracy of < 10 um RMS. AESOP successfully passed ESO's official final design review and manufacturing has commenced. We present performance results from the first batch of newly-manufactured positioners and also report on how the AESOP project is tracking in terms of schedule, budget and risk.",
