Francois:

  • received valves for pressurising the straws -- ready for gluing

 

Hans: 

  • register for the FCC-ee meeting (remotely) in November. Abstract to be submitted today, Michal will present.

 

Zdenko:

  •  wire tension measured on a 20 cm straw monitor
  • need more points on X axis (frequency), possibly different resistors (for longer straws)

 

Michal:

  • lab in b1:
    • gas distribution registered
    • inspection of the gas line moved from Oct. 7 to Nov. 9 due to other more important works
    • Evelyn is finally satisfied with the gas safety
    • for straw pressurisation, a person has to wear personal ODH detector (not required for prototype operation)

 

Johan:

  • building a device for wire tension measurement (sin-wave excitation by a current passing through the straw)
