Patent ID: 7317369

Claim:
A superconducting magnet coil configuration comprising: a first end flange; a second end flange, said first and said second end flanges defining and limiting a substantially cylindrical winding chamber; a first hollow cylindrical filler, said first filler having a first filler inside radius, a first filler outside radius, a first filler first end, and a first filler second end, said first filler second end disposed adjacent to said second end flange, said first filler defining and limiting a first winding chamber portion between said first end flange and said first filler first end; a second hollow cylindrical filler, said second filler having a second filler inside radius, a second filler outside radius, a second filler first end, and a second filler second end, said second filler disposed within said winding chamber substantially coaxially with respect to said first filler, said second filler inside radius being greater than said first filler outside radius, wherein said second filler first end is disposed adjacent to said first end flange, said second filler defining and limiting a second winding chamber portion between said second end flange and said second filler second end, said second chamber portion disposed radially outside of said first filler; and a superconducting strip conductor continuously wound in several solenoid like layers within said first chamber portion and within said second chamber portion and passing through an overlapping axial region between said first filler and said second filler to travel from said first chamber portion into said second chamber portion, wherein said overlapping axial region defines a notch region of reduced current density, said first filler creating a first blind region and said second filler creating a second blind region.
