	JPG 24 bit 1536x1036 631KB 1024x690 151KB	False color fractograph of OI-ST MJR Nb₃Sn filaments. The Nb₃Sn grains fracture at their grain boundaries, providing the contrast required to analyze their size and distribution. The remaining unreacted Nb islands (this strand is only partially reacted) are pulled up into ridges by the fracture process. The original FESEM image has been tinted to make it more dramatic. A similar cross-section is shown in the next page but is in the form of a 3-d anaglyph image. Unreacted strand supplied to the UW by Oxford Instruments Inc. - Superconducting Technology, Carteret, NJ.
	JPG 24 bit 1231x829 941KB 1024x692 327KB	False color fractograph of SMI PIT Nb₃Sn A15 layer. FESEM image colored for effect (a rejected image for the annual ASC Holiday/New Year card). Unreacted strand supplied to the UW by Shapemetal Innovation B. V., Enschede, The Netherlands.
	JPG 24 bit 2462x1817 1.7MB 1024x756 129KB	False color image of filaments in polished cross-section of Furukawa ITER Nb₃Sn strand. Note the exceptional uniformity and the barely discernable extra spacing between the original bundles of 19 filaments.
	JPG 24 bit 2462x1817 3.4MB 1024x756 339KB	Another false color variant on the Furukawa ITER strand. The unreacted Nb cores (green) are more visible here. FESEM image.

	JPG 24 bit 616x480 171KB 616x480 64KB	False color images of Nb₃Sn filament extracted for IGC-AS ITER strand. FESEM image. The filament as approximately 1/25 the thickness of a sheet of paper.
	JPG 24 bit 2024x1485 679KB 1024x752 97KB	13 µm diameter NbTiTa filaments etched out of IGC-AS Nb-Ti-Ta strand for FNAL-LHC IR Quads. FESEM.
	JPG 24 bit 1447x768 698KB 1024x544 176KB	Montage showing design of IGC-AS high J<sub>c</sub> (critical current density) internal Sn strand. Heat treated strand supplied to the UW by IGC-Advanced Superconductors, Waterbury, CT.
	JPG 24 bit 1515x1447 849KB 804x768 131KB	Deep etch of IGC-AS internal Sn strand (Cu removed by etch).
	JPG 24 bit 1536x874 773KB 1024x582 144KB	False color FESEM image of deep-etch IGC-AS Nb₃Sn strand.
	JPG 24 bit 980x720 78KB 980x720 19KB	A windows background image showing Nb₃Sn filaments exposed by deep Cu etch.
