REBCO涂层导体沿其长度方向具有很高的抗拉强度。然而，当对磁带表面施加牵引力时，它们对分层很敏感，在煎饼卷绕中，牵引力对应于径向拉应力。出于这个原因，大多数REBCO磁体是干式缠绕的(不是浸渍的)。干式绕组的缺点之一是导热冷却到低温(低于20K)时效率较低。开发了边缘浸渍结构来缓解这一问题，但在转弯之间保留了柔软的不粘绝缘层。在本文中，我们提出了一种改进的煎饼结构，具有边缘浸渍的优点，但使用了薄绝缘涂层的哈氏合金带来加固绕组。首先对这种结构的力学行为进行了评估，然后在大背景磁场下进行了大电流试验验证。然后通过快速斜坡和快速放电来测试绝缘性能。
REBCO Coated Conductors have high tensile strength along their length. They are however sensitive to delamination when traction force is applied on the tape surface, which in a pancake winding corresponds to radial tensile stress. For this reason, most REBCO magnets are dry-wound (not impregnated). One of the drawbacks of dry winding is that conduction cooling to low temperature (below 20 K) would be inefficient. Edge impregnation structures were developed to mitigate this problem but retaining a soft non-stick insulating layer in between the turn. In this paper, we propose an improved pancake structure with the benefits of edge-impregnation but using Hastelloy tape with thin insulation coating to reinforce the winding. The mechanical behavior of such structure is first estimated then validated with high current tests under large background magnetic field. The insulation performance is then tested by rapid ramping and fast discharge.
