  4. Infrastructure status • HARDWARE: • MIC1: high magnification obj (100x) • MIC2, MIC3: currently working for scanning of OPERA events • MIC4, MIC5: devoted to plate changer tuning up to now • SOFTWARE: • Computing infrastructure upgraded to “Chrysalis Gamma Edition” • All data taking with ScanGrid now (3 servers currently installed and working)  thanks to Cristiano. • Local DB scheme upgraded to last one and publication started  thanks to Cristiano

  5. Scanning Speed • TotalScan time per emulsion sheet (with fog between 8 to 10) : • Before ScanGrid  from 45-90 (acq.) • After ScanGrid installation  ~10 min (acq.) + plate-change + mark search • Total scan of 13 plates (1 cm2) ~ 15 min x13 ~ 3 h • For not-troublesome bricks: 1-2 bricks / (2 days) / microscope • ( dominated by CS-brick connections troubles  large area scanning of several plates to search for predictions, ...): • 2 microscope available up to now. • 1 more microscope can be available now (with plate changer). 5

  6. OPERA event examples (just one)

  11. DATA Publication in Central DB • Publication is started ( thanks to Cristiano again): • Pub brick: 19 • Pub Scanback: 19 • Pub TS: 14 • Pub Vertex-feedback: 0 (*) (*) many vertices reconstructed with FEDRA framework Feedback-publication is now possible thanks to Luca but additional time is needed to put vertex/tracks statistics in correct format since non-persistent data model in FEDRA exist for vertices.  vertices processing in progress
