Analysis of Electron Beam (Jeon) She managed to analyse both cosmic-ray data and beam test data using the present SciFi software. First, she will estimate the efficiency and Npix for cosmic-rays. 2. Efficiency vs 1/cos(th) (Jeon) She plotted Npix and efficiency as function of 1/cos(th) for cosmic-ray muons with real detector. 3. Reprocess Ishida reprocessed all data and MC data. He checks the overlap between penetrating muons from 1kton and neutrino events in SciFi. It is less than 1%. He will estimate it. 4. IIT maintenance etc (Iwashita) Kobe group and Hamamatsu finished the IIT maintenance. They adjusted the bolt fixing the 1st stage IIT and the 2ns stage IIT. Tanaka et al studied the gate width of MCP with LED. We will take cosmic-ray data with a new gate width (60microsec or so) after looking at Tanaka's data carefully. EL data will be taken then. Water leak check will be done when EL calibration is done. We observe that the black sheets covering SciFi detector become old and torn. In November, we will double the black sheets. 5. New official plots (Walter and Boyd) They are almost ready. //
