7 NGC deliveries and production in 2008/2009 Systems are due for: MUSE (prototype +) d e h is KMOS l p m SPHERE o c ac lzimpol l A Lab usage Two successful revisions of Basic and Transition Board 32AQ Board unaltered Produced 7 power supply units Developed new 2-board housing with fan (for laboratory use only) Stock ~sufficient for deliveries in 2009 to: KMOS MUSE SPHERE ZIMPOL

8 NGC-AO Plan: Develop standard WFS module for all forthcoming VLT AO systems Test controller from Marseille / OHP / Grenoble: OCam Combine NGC digital and OCam analog electronics General sfpdp I/F to SPARTA at LLCU level Status: Bias and clock-driver boards received from OCam NGC sequencer board derived from NGC basic board (Xilinx Virtex-5 instead of II-Pro) ü Firmware prototyped First laboratory light achieved in November Waiting for ESO-Ocam sfpdp development starting

15 X-shooter ü FIERA software defines 2 nearly fully independent virtual cameras on one common front-end electronics VIS system (with MIT/LL CCID-20) UVB system (with e2v CCD44-82) Requirements-compliant systems delivered to Paranal

16 Giraffe upgrade First deep-depletion device with dual-layer coating (e2v) Successfully commissioned in 2008 May Prototype for VIMOS red upgrade 10,000 s Thicker silicon offers decisive advantages - but also suffers more particle hits ü Much reduced fringing Major improvement in red sensitivity

17 OmegaCAM: from Lagerhalle to Bodega 2008 Bodega Paranal 2006 Storage Hall Garching 2005 Assembly Hall Garching

18 OmegaCAM: between the bodegas Shipped to Paranal Re-assembled ü Fully successfully tested ü I/F instrument / detector system verified ü Packed and safely stored Awaiting VST Filters from Barr Ass. broken (again )

19 OmegaCAM: one CCD failed Here it is Typically asked questions: How bad is it? It s very bad Is damage due to transport? (Identical CCD died No, it isn t years ago under similar circumstances) When will CCD be un-kaputted? CCD can t be repaired Can it be replaced? Yes. At cost and risk Will it be replaced? It depends

22 ZIMPOL (SPHERE) Originally, ZIMPOL was supposed to provide a VLT-compliant detector system Now, the ODT may more nearly be supplying a ZIMPOL-compliant detector system Comprehensive FDR documentation submitted NGC system produced

23 UVES red upgrade EMMI red released for cannibalism Installation in 2009 July Miscellaneous VIMOS red upgrade Contract with e2v signed in 2008 (?) 5 deep-depletion CCDs due before 2009 August Installation in P84 Ultra-stable Cryostat Procurement of parts ESPRESSO Phase A Broad survey of detector options FIERA 2009 releases of VLTSW (incl. enhancements) Pulpo1 Multiple clean-ups after upgrade attempts on LSP MIT/LL Phase 4 Have given up on receiving any devices
