TRIPLET
Triplet cable dimensions have been fixedSecond iteration later in the year20% margin looks challenging, possibility of splitting the CERN magnets to be considered

D1
We will use the LHC MB outer layer cableInner not possible due to short lengthKEK not interested in enhanced insulation30% margin could be large, possible to go for 6 T and 6 m length

D2
We will use the LHC MB outer layer cableField quality seems critical, pushing towards lower fields (3.5 T)Aperture still to be fixed: 95 better for FQ, 105 for energy deposition

Q4
We will use the LHC MB outer layer cableShort lengths available, not affecting the spare cableAdv: no quench heaters, cable available, but large currentCEA interested in using enhanced insulation
