    Time: 17:30(JST) - Site: KEK ATF LC container Participants: Tauchi, Terunuma, Okugi, Kuroda, Naito, Yamanaka, Kamiya(WebEx), Oroku(WebEx) * Plan to enlarge the present IP laser hut to contain a new IP-BSM laser - Power supply: Current one can be used by switching - Cooling water: No additional chiller inspect whether the present chiller can be used for both lasers - Optical table: Bigger table can be used. - After the expansion of the laser hut, it is inevitable to share the same laser hut with MONALISA group. - It is desired to separate the laser hut. (prepare a setup to divide the hut) * Decision of Beam Optics - Beam current: higher is better - Repetition rate: faster is better Naito-san will try to prepare the hardware for 3 Hz operation. - Horizontal beam size: don't want to focus further (last time: sigma_x = 10 um) It was observed the background become larger during Q-scan using QD0 - Vertical beam size: - At first, 4..58 deg crossing angle, 6.7 um fringe pitch will be used in the interference mode - to observe the fringe pattern by the Compton photon signal, less than 1 um beam size is desired. * New laser - specification of the laser is fixed. - it will be delivered to KEK end of September.
