高精度漂移室的铝场丝蠕变效应的研究

The Creeping Effect Study of Aluminium Field Wire for High Precision Drift Chamber

报道了对铝场丝蠕变效应研究的结果。铝丝有蠕变效应， 不同丝只是显示的效应大小不同，相比而言，１００ μｍ 的镀银铝丝效应较小。

The experimental results of the creeping effect for aluminium field wire are reported. These wires show long term creeping effect. There are different reductions of wire tension between several types of Al wire. For comparision the creeping of φ100 μm silver plated Al wire is less than others and this wire is a good candidate of the field wire in the construction of low momentum and high precision drift chamber.
