    Participants: Tauchi, Terunuma, Okugi, Kuroda, Kubo, Oroku, Yamanaka, Kamiya(WebEx) Time: 16:30(JST)~ * Screen Monitor and Knife Edge - add tungsten wire scanner for vertical beam size measurement at the IP - better to attach several wires - Wires should be attached to the end so that easily incerted * Background Photon Reproduction with Computer Simulation - It seems not to be a important issue. - Rather, it may be useful to study SAD calculation * MONALISA installation - Regaring the phase stability, the MONALISA system doesn't affect so much to the Shintake monitor. - However, it is the urgent task to measure beam size with the interference mode. So it is desired to install the MONALISA after the confirmation of this measurement. * Chamber Replacement at the Final Bending Magnet - Originally, the chamber in stock is planed to be altered to have larger aperture. - Because of the residual radiation of that chamber, the new chamber becomes necessary * Phase Stability - 1 minute phase stability is within tolerance (smaller than table vibration) - It is desired to find out the reason why the phase drifts in long term.
