  1. LNGS Scanning Station Status Nicola D’Ambrosio (LNGS Group) Ankara, 2 April 2009

  2. Scanning Station: General Status • Scanning activities Restarted (from 18/3) • 6 Microscopes operative 8 within next week • The new network Infrastructure tested and operative • More powerfull critical machines: • FileServer, DataServer , domain server and Storage • Array (Oracle database and Raw Data) • New 9 TB storage disk array (RAID 5) • New 4 processing machines ( 8 core , 8GB ram per PC) for a total of 7 dedicated machines for High Fog Scanning (Other additional 3 can be used )

  3. Scanning Station: new network and machine infrastructure Scanning Station net (172.17.12.x) 13 Microscope’s PC 2 Domain Servers 10 Processing machine LNGS net Router Firewall Gigabit Switch 5 data server machine 2 Storage disk array (12 TB)

  4. Scanning Station: Lyon Microscope 3 New Microscopes mounted and checked (hardware) Next week: cabling, software installation and first functional measurements If everything proceed properly Ready within the end of April

  5. existing 8 LNGS microscopes moved in their final position

  6. Scanning station scanning capability • Input for the calculation: • Microscopes: 11 • 24 hour/microscope • Nominal speed • contingency and dead time • Scanning station capability: ~ 2300 cm2/day • Taking in account last exstimation presently we need : • ~ 140 cm2/event (10% zone superposition), to be compared with 50 cm2 foreseen for the scanning of the first brick (See Luillo talk…) • We should take into account a speed reduction of about 75% due to the lowered threshold in the image processing .This could be compensate with: • a wider usage of ScanGrid: more tracking servers • different efficiency optimization • Software improvement

  7. About 75% shifts covered ( 2009 < 40% )
