Title:
SUPERCONDUCTING MAGNET APPARATUS
Document Type and Number:
WIPO Patent Application WO/2015/098588
Kind Code:
A1
Abstract:
Provided is a superconducting magnet apparatus provided with a superconducting coil, wherein high magnetic field uniformity is obtained while the length of the superconducting magnet apparatus in the axial direction is kept low. This superconducting magnet apparatus is provided with a main coil (10). The main coil (10) is provided with a first coil (11) and a second coil (12) that has the same central axis as the first coil (11) and is disposed on the outside of the first coil (11) in the radial direction. The shapes of the first and second coils (11, 12) are set so as to minimize magnetic field non-uniformity under the conditions that 400 mm ≤ D1o ≤ 950 mm and 0.2 ≤ ∆D/D1o ≤ 0.7, where D1o is the minimum value for the internal diameter of the first coil (11), D2o is the minimum value for the internal diameter of the second coil (12), and ∆D = D2o - D1o.
