Abstract

Five SOAR instruments are being designed for high-resolution imaging/imaging spectrophotometry across the isokinetic field and queued/remote observing. Wavefront tilt will be sensed in instruments and corrected by jittering M3. SDSU-2 'Leach' controllers under LabVIEW will operate most detector arrays. All optical instruments emphasize high UV throughput, and will use pairs of UV-enhanced MIT/LL 2 by 4 K CCDs. The University of Sao Paulo may provide a 1500- element integral field lenslet array that is fiber-coupled to a compact spectrography. VPH gratings will be used in this instrument and in the multi-slit spectrometer from the University of North Carolina at Chapel Hill. CTIO will provide an optical mosaic imager with 'trombone'-style ADC, and may also upgrade their IRS with its large complement of existing gratings to a 1 by 1K Hawaii array. Michigan State University may build a 4 by 4K near-IR imager with tunable Lyot filter. Most instruments will be clustered at Nasmyth ports where payload totals 4400 kg. Facility units will allow calibration while another instrument is doing science. The baseline for mechanism control is LabVIEW under Linux in a Compact PCI chassis that is fiber-linked by MXI-3 to a dedicated PC.
