Dear colleagues,

The Asian Committee for Future Accelerators (ACFA) joint Linear
Collider Physics and Detector Working Group and the International
Linear Collider (ILC) Global design effort (GDE) would like to invite
you to the joint ACFA physics and detector workshop and the GDE
meeting on the International Linear Collider (TILC09 for short) to be
held in Tsukuba, Japan from Friday April 17th through Tuesday April
21st, 2009 at EPOCHAL Tsukuba in Tsukuba City, Japan.

Details of the meetings will be subsequently posted at .
This meeting is the eleventh in the series of meetings on the physics
and detector of the ILC organized by the ACFA joint Linear Collider
Physics and Detector Working Group. It also represents the eleventh of
the major meetings to host GDE discussion which pursues the
development of the design and project planning for the ILC accelerator
systems. The two meetings will share the opening plenary and closing
plenary sessions on the first day (April 17th) and the last day (April
21st). Besides the parallel sessions on the middle three days,
important agenda of the meetings include (1) Accelerator Advisory
Panel reviews for GDE and (2) initiation of the IDAG review process of
the Letters of Intent for detector systems.

The rough time-line toward the meeting date is as follows :

- Initial announcement: Now
- Early registration: To start shortly and continues
up to January 31, 2009
