    1. 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.
