TESLA Technology Collaboration (TTC)

Nov 5, 2012, 8:00 AM → Nov 8, 2012, 1:00 PM US/Eastern

CEBAF Center Auditorium (Jefferson Lab)

Charles Reece (Jefferson Lab), Olivier Napoly (CEA Saclay)

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.

Program Committee:

• Olivier Napoly, CEA
• Camille Ginsburg, FNAL
• Nobu Toge, KEK
• Wolf-Dietrich Möller, DESY
• Charles Reece, JLab

** Please note the change from daylight to standard time begins on November 4 **

One of the distinguishing features of the European Spallation Source, currently under development in Lund, Sweden, is its commitment from the beginning to be a sustainable research center. In terms of energy use, this commitment takes the form of stressing energy efficiency, use of renewable sources to power the ESS and recapturing the significant waste heat from the site for use in the Lund district heating system. This talk will describe the challenges, current status and future plans of this effort.
