1. SQXF Coil 2 Impregnation Status & Plan Fred Nobrega 09/09/2014

2. SQXF Coil 2 Status Outline Splice block removal, bolts seized –Next coil use boron nitride Power lead splice complete –SnPb solder & activated flux used –Very difficult using silver solder and low chloride flux (Nokorode) Heater/VT trace hi-pot test passed, 1kV Straight section (poles) preparation complete 2 voltage taps out of place requiring jumpers, DR written.
