在 LHC 主磁体中，使用卢瑟福型电缆，涡流损耗和动态磁场误差很大程度上取决于交叉 (Rc) 和相邻 (Ra) 股线之间的电阻。使用直流电方法在低温下研究了由带有预选涂层的绞线制成的电缆。解释了链间接触的重要性。描述了电阻屏障的特性、用于测量电缆电阻的直流方法以及样品制备。最后给出了各种条件下的电阻，并讨论了电缆处理对接触电阻的影响。
In the LHC main magnets, using Rutherford type cable, the eddy current loss and dynamic magnetic field error depend largely on the electrical resistance between crossing (Rc) and adjacent (Ra) strands. Cables made of strands with pre-selected coatings have been studied at low temperature using a DC electrical method. The significance of the inter-strand contact is explained. The properties of resistive barriers, the DC method used for the resistance measurement on the cable, and sample preparation are described. Finally the resistances are presented under various conditions, and the effect is discussed that the cable treatment has on the contact resistance.
