CCDTL (F. Gerigk)

  • a Memo has been submitted to justify a direct contract with BINP for the construction of the CCDTL supports

Windows (F. Gerigk)

  • the decision of whether to construct the Linac4 windows in-house or together with Thales has been postponed to the next FC meeting in September.
  • Presently we wait for the results of the CERN brazing test, which are expected for Mid May. The brazing was delayed due to the work on the RFQ.
  • If the brazing is successful CERN will order enough ceramics for a pre-series, while a decision is taken on a revised offer from Thales.

Transport (F. Gerigk)

  • Caterina is studying options to transport RF structures with arms, pre-study results expected for end of May

PIMS (F. Gerigk)

  • asked IPJ for additional precision machined holes to be able to mount/dismount alignment arms. Waiting for reply.

movable tuners (F. Gerigk)

  • Approval process of drawings is finished. Remark must be added to technical specs that all EBW activities have to be done after the brazing.

DTL (S. Ramberger)

  • Laser tracker measurements before and after heat treatment show deformations of about 30Ám. The measurements confirms that a heat treatment is required and that the oversize material (1mm) is sufficient for the purpose. The inner diameter was checked to be in or very close to tolerances.
