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

4. 3 New Microscopes mounted and checked (hardware) Next week: cabling, software installation and first functional measurements Scanning Station: Lyon Microscope 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 cm 2 /day Taking in account last exstimation presently we need : ~ 140 cm 2 /event ( 10% zone superposition), to be compared with 50 cm 2 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% )
