Description

さらに、後述するように、補強テープ線１１の厚さを適切（０．０２０ｍｍ超０．０６８ｍｍ以下、より好ましくは０．０３５ｍｍ以上０．０６５ｍｍ以下）に設定することで、電流密度の低下も最小限に止めることができる。すなわち、電流密度減少の最小限化および超電導コイル５０の劣化防止を両立することができる。 Furthermore, as will be described later, by setting the thickness of the reinforcing tape wire 11 appropriately (over 0.020 mm and 0.068 mm or less, more preferably 0.035 mm or more and 0.065 mm or less), the current density is also reduced. It can be minimized. That is, it is possible to achieve both minimization of current density reduction and prevention of deterioration of the superconducting coil 50.

また、超電導コイル５０によれば、後述するように、補強部としての補強テープ線１１の厚さを適切（０．０２０ｍｍ超０．０６８ｍｍ以下、より好ましくは０．０３５ｍｍ以上０．０６５ｍｍ以下）に設定することで、電流密度の減少を最小限に止めつつ、従来よりも薄膜超電導線１の各層に生じる負荷応力に起因する剥離、変形、クラック等の発生を防止し、超電導コイル５０の劣化を防止することができる。 Moreover, according to the superconducting coil 50, as will be described later, the thickness of the reinforcing tape wire 11 as the reinforcing portion is appropriate (over 0.020 mm and 0.068 mm or less, more preferably 0.035 mm or more and 0.065 mm or less). By setting to, it is possible to prevent the occurrence of peeling, deformation, cracks, etc. due to the load stress generated in each layer of the thin film superconducting wire 1 as compared with the prior art while minimizing the decrease in current density, and deterioration of the superconducting coil Can be prevented.

さらに、超電導テープ線１０および当該超電導テープ線１０を用いた超電導コイル５０によれば、補強部としての補強テープ線１１の厚さを適切（０．０２０ｍｍ超０．０６８ｍｍ以下、より好ましくは０．０３５ｍｍ以上０．０６５ｍｍ以下）に設定することで、従来よりも効果的に薄膜超電導線１の各層に生じる負荷応力に起因する超電導コイル５０の劣化を低減することができる。すなわち、電流密度の減少を最小限に止めつつ、薄膜超電導線１の各層に生じる負荷応力に起因する剥離、変形、クラック等の発生を抑制することができる。 Furthermore, according to the superconducting tape wire 10 and the superconducting coil 50 using the superconducting tape wire 10, the thickness of the reinforcing tape wire 11 as a reinforcing portion is appropriately set (over 0.020 mm to 0.068 mm or less, more preferably 0.8 mm) . By setting to 035 mm or more and 0.065 mm or less, deterioration of the superconducting coil 50 due to load stress generated in each layer of the thin film superconducting wire 1 can be reduced more effectively than before. That is, it is possible to suppress the occurrence of peeling, deformation, cracks, etc. due to the load stress generated in each layer of the thin film superconducting wire 1 while minimizing the decrease in current density.
