from to (US/Eastern)
at Jefferson Lab ( CEBAF Center Auditorium )
12000 Jefferson Ave. Newport News, Virginia
Description 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 Jefferson Lab 5-8 November 2012.
