- Flat and clean cross section of the superconductive wire
- Structure of Nb3Sn in the Cu matrix
Purpose: The shape of the wire is difficult for ion beam slope cutting.
Goal: Cross sectional preparation to see the structure of the wire.
Process Description: (benchmark values for this particular sample)
1. Embedding in between two Si slices
2. Grinding the cross section with the Leica EM TXP
(6µm diamond foil) to get a flat surface
