• Single tunnel configuration was discussed with the RDR-type HLRF system and with the DRFS type.
• The ILC cryomodule positioning in the single tunnel was discussed referring to examples (XFEL, LHC, Project X, S1 Global)
• Asian Team design with 3-D approach has been well progressed during the half period of FY2010.
