Design of the 13C detection coils. (a) Pair of counter-wound spiral resonators. Each resonator employs two 4-turn YBCO spiral structures with opposite handedness coated onto either side of a sapphire substrate. To reduce magnetization, the HTS resonators are slit into 14 fine parallel fingerlets. The slits cause each mode to split into a family of modelets. (b) The modelets of one single-sided spiral coil as simulated using IE3D.
