1. Helene Felice With input from Dan C, Maxim… Possible options for coil wiring

2. Option 1: BNL approach Pig tails potted with the coil Spliced with full length wires PROS Strain relief of the wires due to potting Convenient given the tight space in the mold CONS Once the magnet is assembled the splice area is not accessible Not compatible with ribbon cable 09/23/2014H. Felice2

3. Option 2: LBNL approach so far Full length wires added after potting and secured with “green” (epoxy) putty PROS Compatible with ribbon cable CONS More labor intensive than option 1 Surface finish not as good as option 1 09/23/2014H. Felice3

4. Option 3 Ribbon cable “impregnation” Rolled ribbon (full length) captured in the impregnation mold With or without connector PROS Strain relief of the wires thanks to potting Compatible with ribbon approach CONS Is there enough room in the QXF mold Never done in LARP => HQ practice impregnation at LBNL? 09/23/2014H.
