Purpose of the R&D project was to : (1) develop magnet cable for 2000A and 60 m long with complete mineral insulation, (2) employ new indirect cooling method for the coil.The project continued two years, we investigated the drawing method of the mineral insulation cable (MIC) of more than 60 m length with relatively large cross section. After several trials, we finally decided to employ double stage drawing.In the second year, we prepared several short samples of 2000A class MIC. Bending tests and insulation tests were performed with them, and final cross section of the 2000A class MIC was determined. The last and main samples of 60m MIC were thus fabricated. Number of the finally fabricated MIC is three. Now the magnet coil is under construction. The temperature control of the soldering between MIC and cooling water pipe was some technical difficulty. The excitation test of the new coil is scheduled in the next fiscal year.

本项目的研究目的是：（1）开发2000 A、60 m长的完全矿物绝缘的电磁电缆;（2）采用新的线圈间接冷却方法。本项目历时两年，研究了60 m以上、截面较大的矿物绝缘电缆（MIC）的拉拔方法。经过几次试验，我们最终决定采用双阶段拉伸，第二年，我们制备了几个2000 A级MIC的短样品。对它们进行了弯曲试验和绝缘试验，并确定了2000 A级MIC的最终截面。由此制造了60 mMIC的最后和主要样品。最终制作的MIC数量为3个。目前，磁线圈正在建设中。MIC与冷却水管焊接的温度控制是一个技术难点。新线圈的励磁测试定于下一财政年度进行。
