TESLA Technology Collaboration (TTC) Meeting

Asia/Shanghai
Main Building, Room A214 (IHEP, Beijing, China)

Main Building, Room A214

IHEP, Beijing, China

Chuanxiang (vice-Chair) Tang (Tsinghua University) , Jie (Chair) Gao (IHEP) , Kexin (vice-Chair) Liu (Peking University)
Description
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.

    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.

    You are welcome to the bi-yearly TTC meeting hosted in Beijing by the Institute of High Energy Physics, Chinese Academy of Sciences (IHEP, CAS)Peking University and Tsinghua University.

    The ILC-GDE SCRF meeting will be held at IHEP right after the TTC meeting from December 8 afternoon to December 9 noon, 2011. The objectives are to: discuss S1-Global progress report to be completed, discuss the TDR SCRF baseline designs, focusing on cavity and cryomodule-cryogenics, and prepare for the SCRF Baseline Design Review (BTR) at KEK, January 19~20, 2012.

    • WG-3 Session 4 Main Building, Room A214

      Main Building, Room A214

      IHEP, Beijing, China

      Cryogenics and cryostats : savings in cooling power.
      Scope: Cutting operational costs through the reduction of cryogenic power is of generic benefit for SCRF systems and an obligation for CW operation. Cryogenics 4K and 2K higher efficiencies, better insulated and thermalized cryostats, and better magnetically shielded cavities are, among others, means which should be reviewed by this Working Group. Some trends and lines of research should be drawn at Beijing, so that the progress would  be reviewed at our next TTC meeting in 2012.

      Cryomodule Test Results and Analysis.
      Scope:The status of integrated cryomodule cold RF tests should be reviewed transversely to all applications and all beams: ILC, XFEL, Cebaf, SPIRAL2, NML, etc. The session should focus on getting the lessons and experience from Cebaf2 and SPIRAL2 cryomodules at moderate gradients, FLASH-XFEL modules at medium to high gradients, NML and particularly S1-global at high gradients, and more if it exists. The issues of field gradient degradation; conditioning, breakdown, static and dynamic thermal load of input couplers; performance of tuners; alignment process and stability control cryogenics performance and control should also be covered.
