Recurrent meetings for the follow-up 1-cell 800 MHz Nb cavities fabrication

Friday 11 Jul 2025, 11:30 → 12:30 Europe/Zurich

Zoom (CERN)

Meeting on 11/07/2025:

• New assets created in EAM : FCACSGAN001-AC000001 to 10. Stickers available to put on transport box. The number and QR code code can be engraved on the side of the flange at the end of the fabrication. An additional work order will added to put material control reports (action Franck)
  • Link: Asset FCACSGAN001-AC000001
• The extra niobium material form Ulvac has been received at CERN and is in NDT. Quality control of all the sheets will be done.
• A new tender shall be launched for new material coming from well known suppliers like Tokyo Denkai or Ningxia (action Claudia). Exact dimensions shall be provided by Laurent to optimize this new procurement (action Laurent)
• Laurent informed that the production of the 2 first single cell cavity has re-started. 
  • 4 beam tubes have been welded, radio is ok. the tubes are in "calibration" (precision and fine tune forming steps).
  • the extrusion of the half cells is on-going.
  • when the RF tooling is ready we can start frequency measurmeents on the first half cell built with the materail from IJCLab (Akira).
