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.

研发项目的目的是：（1）开发2000a的磁铁电缆，并具有完全矿物绝缘的60 m长，（2）对线圈采用新的间接冷却方法。该项目持续了两年，我们研究了矿物绝缘电缆（MIC）的绘图方法，其长度超过60 m，横截面相对较大。经过几次试验，我们终于决定使用双阶段图。第二年，我们准备了2000A类麦克风的几个简短样本。对它们进行了弯曲测试和绝缘测试，并确定了2000A类MIC的最终横截面。因此，制造了60m MIC的最后一个和主要样本。最后制造的麦克风数为三个。现在，磁铁线圈正在建造中。麦克风和冷却水管之间焊接的温度控制是一定的技术困难。新线圈的激发测试计划在下一个财政年度进行。
