N2 - We study the new-type of cryogen, which consists of solid nitrogen and liquid neon, for the performance improvement of the HTS application systems. Bi-2223/Ag multifilamentary tape is impregnated with the solid nitrogen-liquid neon mixture, and the temperature at the surface of the tape is measured by applying the overcurrent. The cryogen is produced by the GM cryocooler, and the initial temperature is set to be 25.1 K. It is shown that the thermal behavior of the tape is improved drastically by impregnating with the mixture compared to the solid nitrogen alone. The reason for this result can be explained that the heat generated in the tape is transferred by the liquid neon to the solid nitrogen. Therefore, the proposed mixture is important for the conduction cooled HTS coil applications such as SMES. A detailed explanation of the experiments is presented in this paper.
