CCDTL

• Technical meeting was a success. All open issues were discussed
• Shipping list is under preparation
• Simulations:
  • 2 modes found in 3 cell model with 2 coupling cells and one cell in short circuit. Further studies ongoing to understand model

PIMS

• Construction is ongoing
• Investigation is in progress, if EB welding could be done in Juelich

Buncher Cavity

• Feedback from Poland:
  • Line inside cavity detected. It should not be an problem in later operation so no additional machining will be done.

DTL

• High Power Test ongoing
  • about 250 kW in the cavity with more than L4 duty cycle (4Hz, 700sec)
• Tilt sensitivity measurement is still under further analysis
• First drift tube with magnet inside is ready for final welding.
  • Magnetic shielding is necessary
  • Drift tube will be cut open afterwards and final checks will be done
  • First “final” drift tube will be produced afterwards

HOM

• Analyzing longitudinal simulation results in case of a chopped beam. Effect of chopping seems to be an issue, especially if HOM hits a machine line generated by the chopping. Further analysis is needed to identify damping limits.
