Ed build wire cleaving holder, 3 perpendicular wires in clamp.
scribe wire outer diameter by rolling wire on surface with scalpel.
insert wires to scribe mark.
cleave with syringe needle that fits OD
Cleaved in air this time, ~ 1 min exposure before pumpdown.
Wires are Cu clad bundle of 50 um subelements, each should be Cu.96Sn0.04 bronze, with Nb3Sn phase polycyrstalline, ~ 1.5 at. % Ti doped, expect Ti at grain boundaries, also Cu. intergranular fracture
No problem with Auger, although Ti hard to find. Small Ti 383 peak found but no 418. First peak is L2,3M2,3M2,3, next is L2,3M2,3M4,5 which involves valence levels. See Maline SS 286 p82 1993 for interpretation of Ti Auger.
