Presents : Yingzhe (IHEP), G kirby, A Foussat (CERN)

Excused:, A Musso, Qingjin

Minutes meeting and actions item list :

• Test schedule :  CB04, CB06 were delivered at IHEP to be tested from end November. IHEP  test station to be installed and commissioned by end November. CB05, CB07 test are scheduled during December. IMP test station might resume operation from mid December.
• Production: CB08 is ready for winding. In the prospect to understand VPI limitations and possible improvements
• Procedure: comments on wet winding procedure by CERN  will be reviewed and a new version of procedure uploaded by IHEP
• VPI Procedure: Some preliminary process description slides shown the details of the first wet winding curing performed by BAMA after assemblying the mould to be leak tested. This is followed by the VPI steps in furnace. It is not understood how the resin can flow inside the mould, how is performed the outgassing of mould and the control of coils temperature. The inlet side shall be clarified.

Actions:

• Pending : All formers manufacture, anodization and inspection reports to be uploaded in MTF.
• Updated procedure of wet winding to be uploaded following commenting.
• A peer dedicated review shall be organised after CB06 test with a presentation by IHEP and the second step VPI process implemented with open issues vs complete VPI should be evaluated. The production of winding beyond CB08 should take into account the outcome of the review recommendations.
