  • Prototype high power test
    • Prototype with magnet in the first DT and anodizing matrix in the LE end-cone conditioned at 3% d.c. (width=1.5msec; repetition rate=20Hz)
    • Further power tests to be defined


  • Russian team at CERN for the CCDTL 4th technical meeting. The construction status at VNIITF and BINP can be followed here
  • The support should arrive at CERN at the end of year to allow the installation of the first module
  • Quality assurance for acceptance test for CCDTL to be defined
  • The RF tests and the leak tests will be done in Russia. The re-assembling, RF and leak tests, water pressure test, laser track will be done at CERN
  • In 3 months after the assembly, each module should be operative: 2 weeks time to be spent for the conditioning of the cavity. To be define breakdown rate and also the way to measure it


  • Indirect measurements of the cells resonance frequencies before and after the welding show change in frequencies. Simulations have been done to estimate the shrinkage according to the calculated frequencies shifts
  • Simulations to calculate the dissipated power density on the interconnecting WG. Maximum value: 0.25W/cm^2. This maximum heat load has been uploaded in Ansys Multiphysics to calculate the temperature on the structure while applying a water flow rate of 8.65 l/min (the temperature of the water is 24 degrees). N.B. constant heat load has been considered on all 4 surfaces of the interconnecting WG. Furthermore also a simulation with the double power density has been performed
