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 )

Scanning Station: Lyon Microscope

If everything proceed properly Ready within the

end of April

existing 8 LNGS microscopes moved in their final position

Scanning station scanning Scanning station scanning capabilitycapability 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

About 75% shifts covered ( 2009 < 40% )
