| Abstract: | The development of a Bi2223/Ag tape HTS magnet with a central field of 3. 0T and a stored energy of 3510 is in progress. The magnet consisting of 32 double pancakes with an inner diameter of 150mm and outer diameter of 272mm will be made of homemade Bi2223/Ag HTS material offered by the Northwest Institute for Non-Ferrous Metal Research. At the temperature of 20K the magnet will work with a rated current of 100A and its designed critical current Ic is 132A. The magnet assembly consisting of 4 double pancakes has been conducted at the temperature near 20K and the magnet critical current Ic reach 140A with a maximum perpendicular field of 1.14T at the conductor. The experimental results of the four double pancake magnet assembly show that the design goal of the 3. 0T, 35kJ HTS magnet could be realized. |
