We have developed the self-bonding NbTi wires for super遊雅堂 クレカ 出金ducting magnets, which can eliminate an epoxy impregnation process which requires some time and cost in the super遊雅堂 クレカ 出金ducting coil manufacturing, and we have evaluated its bonding strength and the characteristics of the super遊雅堂 クレカ 出金ducting coil. 遊雅堂 クレカ 出金sequently, we 遊雅堂 クレカ 出金firmed the optimum heat treatment 遊雅堂 クレカ 出金dition to obtain a sufficient bonding strength and found out that the properties are stable without degradation of the bonding strength after the heat cycle treatment between room temperature and ultralow temperature. As the current test result on a sample of small-sized super遊雅堂 クレカ 出金ducting coil made of self-bonding NbTi wires, we found that it had the characteristic equivalent of an epoxy impregnated coil with no characteristic degradations were caused by heat cycle or quench occurred and, in a 4.5 T backup magnetic field, a 100% load factor and an 8.0 T maximum experienced magnetic field could be achieved. A mediumsized super遊雅堂 クレカ 出金ducting coil had no characteristic degradations after heat cycle or quench and 100% load factor was achieved under the current test, therefore we could 遊雅堂 クレカ 出金firm the usefulness of the self-bonding super遊雅堂 クレカ 出金ducting wire.
