DESY Hamburg

The mission of the TESLA Technology Collaboration is to advance SRF 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. To this end the Collaboration supports and encourages free and open exchange of scientific and technical knowledge, expertise, engineering designs, and equipment.
The TTC organizes regular collaboration meetings where new developments are reported, recent findings are discussed and technical issues are concluded. The next meeting will be hosted by DESY 24-27 March 2014.
Program Committee:
Olivier Napoly, CEA Camille Ginsburg, FNAL Hans Weise, DESY Eiji Kako, KEK Wolf-Dietrich Möller, DESY
