  1. Subaru Instruments Status SUBARU Instruments Status & Prospects Hiroshi TERADA (Science Operation Division) Summary • MOIRCS: Channel-1 Replacement • Suprime-Cam: CCDs Upgrade • IRCS+AO188: Start Open Use • Updates for HDS, FOCAS, and IRCS • Personnel and Instrument Changes Hiroshi TERADA @ SubaruTelescope 2008 SUBARU Users’ Meeting : 2009/01/16 NAOJ, Mitaka

  2. Subaru Instruments Status 1. MOIRCS: Events in 2008 Engineering-Grade Chip for Channel-1 • ■Detector Replace(Channel-1) • Engineering-Grade Chip • (Oct 2007 – July 2008) • Science-Grade Chip • (July 2008 – ) • ■Replace of Ks-band Filter to • Fringe-free type • ■The open of high-resolution • VPH Grisms • ■Y-band medium-resolution • spectroscopic ability is available • ■Problem in partial-read mode Systematics in Partial-Read Mode Hiroshi TERADA @ SubaruTelescope

  3. Subaru Instruments Status 1. MOIRCS: Channel-1 Replacement Replace to a new Science-grade detector in July 2008. QE map of the new detector ■Similar sensitivity to chip-2 detector, especially at shorter wavelength. ■Good linearity (<<1% at 5000-25000ADU). ■Low dark current (similar to chip2). ■One large cluster of dead pixels. Not used during the imaging observation See the website below for more details. http://subarutelescope.org/Observing/Instruments/MOIRCS/chip1info.html Hiroshi TERADA @ SubaruTelescope

  4. Subaru Instruments Status 2. Suprime-Cam: CCDs Upgrade New FDCCD+Mfront2 w/ new dewar • More stable with pulse tube cooler • Less readout time (1/2) (wipe+erase: 7s / readout: 18s) ■2008 July Replacement successfully done. ■S08B～ Available for Open Use. Hiroshi TERADA @ SubaruTelescope

  5. Subaru Instruments Status 2. Suprime-Cam: CCDs Upgrade On-going work • Non-linearity effect in low signal (<500ADU) • Systematic pattern in flat-image • New SDFRED software by SDFRED team Sensitivity Ratio M17 starforming region taken with New FDCCDs Wavelength (nm) Hiroshi TERADA @ SubaruTelescope

  6. Subaru Instruments Status 3. IRCS+AO188: Start Open Use IRCS w/ AO188 NGS system ■2008 August Engineering restart with full system ■2008 October Shared-risk open use starts. (11.5 nights; so far 8.5 nights) IRCS w/ AO188 LGS system under testing; TBD for S09B 55”x 55” IRCS 52mas Camera Red: H2(1-0) 2.122μm, Green: Brγ 2.167μm, Blue: [FeII] 1.644μm Hiroshi TERADA @ SubaruTelescope

  8. Subaru Instruments Status 4. Updates for HDS, FOCAS, and IRCS HDS Non-Linearity ■HDS - Linearity investigation -->Could be corrected. ■FOCAS - FDCCD upgrade 2008: Design, fabrication, & test 2009: Installation 2010--: Open Use - New VPH grism (R~1000; 600-1000nm) ■IRCS (w/o AO188) - Thermal background Almost back to the previous level @ Cs after NsIR ImgRot recoating FOCAS New Dewar & Cooler Cs @ L-band Recoating ◆ NsIR Hiroshi TERADA @ SubaruTelescope

  9. Subaru Instruments Status 5. Personnel and Instrument Changes Personnels ■AO188 SA: Y. MINOWA ■Suprime-Cam SA: H. FURUSAWA -> M. ISHII (Interim) => TBD Instruments ■AO188 LGS / FMOS Under considerations for S09B open or not. ■AO36 (2000-2008) Decommissioned at the end of S08A Might be dismounted from the Telescope during M1-recoating period in 2010.
