We report on simulation of SNR Gain behavior of cryogenic coils as a function of frequency and coil size in arrays, as well as on an accurate technique for experimental verification of SNR Gains based on Q measurements performed on Cu cooled and high temperature superconductor (HTS) coils. The obtained results identify the advantages of using HTS coils over Cu cooled coils and specify the maximum size ranges for sufficient SNR Gain at different frequencies. New designs for HTS coils of various sizes include frequency tuning based on a dielectric layer introduced between HTS layers.
