Three solenoids have been wound and with MgB2 strand and tested for transportproperties. One of the coils was wound with Cu-sheathed monofilamentary strandand the other two with a seven filament strand with Nb-reaction barriers, Custabilization, and an outer monel sheath. The wires were first S-glassinsulated, then wound onto an OFHC Cu former. The coils were then heat treatedat 675C/30 min (monofilamentary strand) and 700C/20 min (multifilamentarystrand). Smaller (1 m) segments of representative strand were also wound intobarrel-form samples and HT along with the coils. After HT the coils were epoxyimpregnated. Transport Jc measurements were performed at various taps along thecoil lengths. Measurements were made initially in liquid helium, and then as afunction of temperature up to 30 K. Homogeneity of response along the coils wasinvestigated and a comparison to the short sample results was made. Each coilcontained more than 100 m of 0.84-1.01 mm OD strand. One of the 7 strand coilsreached 222 A at 4.2 K, self field, with a Jc of 300 kA/cm2 in the SC and awinding pack Je of 23 kA/cm2. At 20 K these values were 175 kA/cm2 and 13.4kA/cm2. Magnet bore fields of 1.5 T and 0.87 T were achieved at 4.2 K and 20 K,respectively. The other multifilamentary coil gave similar results.Comment: 22 pages, 8 figures, 2 table
