  1. Tsinghua Collaboration Plan Jiaru Shi, CERN On behalf of HuaibiChen, Tsinghua University, Beijing November Collaboration Meeting, CERN

  2. Outline November Collaboration Meeting, CERN • Brief introduction of Accelerator Laboratory at Tsinghua University • Plans for the activity in Tsinghua University

  3. Accelerator Lab at Tsinghua University • Faculty • 15 faculties (3 full Professors)and more employee • About 20 graduate students • Activities • Education (undergraduate and graduate) • Low Energy Linear Accelerators and Their Applications • High brightness electron sources (RF Guns, MPG, Cathode) • High Gradient Accelerating Structures (s,c,xbands) • Compact X-ray Light Source (TTX) • Compact Pulse Neutron Sources (CPHS) • MeV Ultra-fast Electron Diffraction • Advanced Accelerating Concept ( PWFA ) • …

  4. Microwave measurement for RF structure Two based on SNA, two based on VNA November Collaboration Meeting, CERN

  5. Machining Workshop high-precision machine tools and CNC Machine November Collaboration Meeting, CERN

  6. Facility for brazing and baking Medium-T hydrogen furnace High-T hydrogen furnace Laser welding machine      Leak detector   Tool microscope     Annealing furnace Vacuum furnace Baking oven November Collaboration Meeting, CERN

  7. RF Structure R&D November Collaboration Meeting, CERN

  8. Plans November Collaboration Meeting, CERN • Choke-mode-damped structure • To design a choke-mode damped structure as an alternative to the CLIC baseline structure. (Wake field Simulation, RF design, etc…) • Machining, tuning, bonding and brazing on siteTo supply hardware (prototype structures) for high power test and wake field measurements

  9. On going Activities November Collaboration Meeting, CERN • Ph.D Student visiting CERN • T24 test structure to validate the production procedure • (to benchmark against the identical rf design structures built at KEK/SLAC and CERN) • Three batches of cells send to CERN for qualification • Bonding test on going

  10. Funding November Collaboration Meeting, CERN • National Natural Science Foundation of China (NNSFC) • Project: “Research on the physics and key-technology of X-band high gradient accelerating structures”. • Project leader: Prof CHEN Huaibi • For five years from 2012 to 2016 • Material budget: ~30kCHF/a • Manpower: 0.5 Professor, 2 PhD students • Applying University Funding dedicated to international collaboration
