15th ATF2 Project Meeting

Asia/Tokyo
Large meeting room, 2F, Shokuin-Kaikan (KEK, Japan)

Large meeting room, 2F, Shokuin-Kaikan

KEK, Japan

Description
Toward the first goal, i.e. achievement of 37nm vertical beam size, we would like to focus on two major issues of the wakefield and vertical emittance growth keeping in mind that there are other issues such as multipole fields in the qudrupole magnets, electron/laser beam jitters etc. . The primary goals are identification of sources for the wakefieds and emittance growth and establishment of the mitigations. The meeting place is a large meeting room at the 2nd floor of Shokuin-Kaikan, KEK, which is next to the cafeteria.
