  • The measurements uploaded in https://edms.cern.ch/document/3406593 have a precision ~0.1 mm
  • Still some uncertainties in the design that can't be answered ; 
  • The consensus is the design radius is 12 mm and 8.0 mm between the center of the cylinder and bottom plate as measured. 
  • Collective discussion went on: 
    • Nikos agreed to not go for 24 mm diameter as today, but rather for 15 mm as a compromise between field quality & risk 
    • The thickness of the blade plays no role for the beam (only slightly increases losses) but very important for the field stability --> 3 mm 
    • From the beam point of view, the radius at the bottom point (oblong) is better in further improving the beam quality --> OK (to be included in the new design)
    • Total height (opening) no smaller than 15mm given the size of the beam in the BTV ; 
    • Alignment-wise, the groove can be measured and used as reference for alignment.
