<html><body>
Mission of the TTC Meeting FNAL

The mission of the TESLA Technology Collaboration is to advance SCRF technology R & D and related accelerator studies across the broad diversity of scientific applications, and to keep open and provide a bridge for communication and sharing of ideas, developments, and testing across associated projects. Besides other activities the TTC organizes regular collaboration meetings where new developments are reported, recent findings are discussed and technical issues are concluded.
For the FNAL meeting the following Working Groups (WG) are planned:
-WG1 Module issues (XFEL, KEK, ILC, DESY module tests, cw modules)
-WG2 Summary EP, new treatment infrastructure
-WG3 Test facilities: Operating experience, new proposals
-WG4 Input & HOM coupler

In general, the meeting takes place in room 1 West. Few sessions are held in different rooms. In this case the room is indicated on the agenda.
