| Popis: | We have developed a reel-to-reel reaction furnace equipped with seven transverse flow modules, for the continuous TFA-MOD process. Experimental results have revealed that as the wire length increases, the processing parameters need to be adjusted in order to obtain YBCO films with high critical current density ( J c ) than 1 MA/cm 2 at 77 K and self-field. As a result of fabrication under the appropriate process conditions, we have successfully produced uniform tapes with a high performance in a short sample. In the recent progress, heat-treatment conditions have been optimized and the higher gas flow rate was applied to the long tape fabrication, and the I c value of higher than 100 A as the end-to-end one of a 8.5 m long tape was attained. |
