VIRUS: a massively replicated 33k fiber integral field spectrograph for the upgraded Hobby-Eberly Telescope

Abstract: The Visible Integral-field Replicable Unit Spectrograph (VIRUS) consists of a baseline build of 150 identical spectrographs (arrayed as 75 units, each with a pair of spectrographs) fed by 33,600 fibers, each 1.5 arcsec diameter, deployed over the 22 arcminute field of the upgraded 10 m Hobby-Eberly Telescope (HET). The goal is to deploy 96 units. VIRUS has a fixed bandpass of 350-550 nm and resolving power R~700. VIRUS is the first example of industrial-scale replication applied to optical astronomy and is cap… Show more

“…The drum supports the 1000 kg focal surface hardware through a kinematic mount interface. Included in the focal surface hardware are the integral field units (IFU) fibers which feed reflected light to the VIRUS instruments 8 . The rho stage drum drive system consists of a servo motor connected to a low back-lash gearbox, with a capstan on the output shaft.…”

“…Replacing the current Spherical Aberration Corrector (SAC) with the Wide Field Corrector 5 (WFC) will increase the HET field of view from 4' to 22'. In addition, the current science instruments will be supplemented with the Visible Integral-field Replicable Unit Spectrograph 6 (VIRUS). These changes will allow the telescope to conduct the largest survey of distant galaxies ever attempted.…”
