    * TOF frame
        *Main frame was ordered (~450,000 yen).
        *Have not ordered yet; iron sheeld, frame foot, scitillation attacher
    *About Water Cherenkov Detector
        *Final design of one segment (will be done by K.Takeneka)
        *Main frame design can be started since the final desgin is almost fixed.
        *Magnetic field shield / Bucking coil; Need TOSCA calculation

    *Geant4 simulation for one segment WC
        *Comparison with ELPH experiment → Almost reproduced ELPH's results.
    *Optics study of S-2S using turtle
        *Optimization of currents for Q and D, seeing solid angles.
        *There is no detector's cut in this study. → will be done next.



===== K.Takenaka =====
    * Water Cherenkov detector
        *Basic design was done. → will request a quate.
        *Cap attachment will be done using バスコークN or アクリダイン.
            *バスコークN should be tested. Note that アクリダイン was used in HKS experiment in 2009 (JLab E05-115).
