Present: Patric, Daniel, Justin, Marlene, Tobias, Michele

Discussion & Updates:

  1. Facility CAD Model needed by GWA

    • Area to be included in the model was discussed. Action: Marlene to clarify with Fred. Model should include the beamline and racks ±2 m upstream and downstream of the vapor source.

  2. Funding & Budget

    • MPP has discussed funding. Next Step / Action:  GWA to provide budget estimates for this year and next.

  3. Horizontal Angling of Upstream Vapor Source (0.1 mrad)

    • Next Step / Action: Jim to add the angle to the CAD drawing and evaluate how it can be realized.

    • General consensus: implementing the angle should be possible.

    • Action: Marlene & Patric to discuss with the Survey and Alignment team.

    • Action: GWA to define flange tolerances.

  4. Humidity Question (Alejandro)

    • Dew point <12 °C is considered sufficient.

    • Action: Marlene to respond to Alejandro (EN-CV).

  5. 2/3-Way Valve to Save Cooling Water

    • Action: GWA to contact chiller company to assess ease of valve replacement.

    • Action: Marlene to check with Alejandro if reducing chiller flow could avoid changing components.

    • Update: Feedback on chiller positions received; integration team is reviewing options for shorter lines.

  6. Washing of Valves

    • Previously washed only in one position; residual Rubidium oxide remains.

    • Action: To be washed again; need to identify a suitable location. Possibly check with Marc Thiebert.

  7. Cabling Campaign

    • Answers to Tobias’ questions:

      • Cabling the plasma source separately is sensible.

      • Access will mostly not be restricted during plasma source commissioning.

      • No significant risk of delay currently.

        • Action: Tobias to check if plasma source cabling can be included in the first campaign or at the start of the second to benefit commissioning time in 2028.

         

  8. Next Meeting

    • Action: Marlene to organize the next meeting in two weeks.
