  2. Eucard WP 10.8 Summary • Introduction • Automatic Cleaning System • Plasma Discharge Cleaning • Schedule

  3. Eucard WP 10.8 Introduction Coupler preparation Warm coupler part Cold coupler part 3 Weeks Coupler parts after manufacturing Cryomodule assembly Cleaning Assembling Desorption Conditioning

  4. Eucard WP 10.8 Global goals • Actual process • 5 days • No repeatability • Pollution risk from manual handling • Automatic Cleaning System • 3 hours • Full repeatability and control of each parameters • No handling but risk of pollution due to the machine  Main challenge • For mass production (ILC, 16000 couplers?) : improve quality and reduce the time of the preparation Cleaning Assembling Desorption Conditioning Time in days 14 11 0 5 7 3 4 Assembly schedule
