缪子电离冷却实验的第一块磁铁将是形成老鼠冷却通道末端的跟踪器螺线管。跟踪器螺线管的主要目的是为闪烁光纤探测器提供均匀的4T磁场(在1米长和0.3米直径的体积上优于+0.3%)，用于分析电离冷却前后通道中的µ子。跟踪器磁铁的第二个用途是匹配老鼠冷却通道的其余部分和均匀场谱仪磁铁之间的介子束。跟踪器电磁阀由三个300安培的电源供电。分光计的额外调谐由分光计磁端线圈上的一对50安培电源提供。跟踪磁铁将使用一对4K脉冲管冷却器进行冷却，每个冷却器在4.2K时提供1.5W的冷却。跟踪螺线管的最终设计和建造于2006年夏天开始。本报告介绍了跟踪器螺线管的建造进展情况。
The first magnets for the muon ionization cooling experiment will be the tracker solenoids that form the ends of the MICE cooling channel. The primary purpose of the tracker solenoids is to provide a uniform 4 T field (to better than plusmn0.3 percent over a volume that is 1 meter long and 0.3 meters in diameter) spectrometer magnet field for the scintillating fiber detectors that are used to analyse the muons in the channel before and after ionization cooling. A secondary purpose for the tracker magnet is the matching of the muon beam between the rest of the MICE cooling channel and the uniform field spectrometer magnet. The tracker solenoid is powered by three 300 amp power supplies. Additional tuning of the spectrometer is provided by a pair of 50 amp power supplies across the spectrometer magnet end coils. The tracker magnet will be cooled using a pair of 4 K pulse tube coolers that each provide 1.5 W of cooling at 4.2 K. Final design and construction of the tracker solenoids began during the summer of 2006. This report describes the progress made on the construction of the tracker solenoids.
