【摘要】 本文报道对几种铝场丝(φ=80μm的镀金铬丝,φ=100μm的镀银铝丝,φ=80μm的镀银铝丝)蠕伸效应研究的结果。铝丝有蠕伸效应,不同丝只是显示的效应大小不同,相比而言,φ=100μm的镀银铝丝效应较小,在低动量高精度漂移室的建造中用作场丝是好的候选者。更多还原

【Abstract】 The experimental results of the creeping effect for several types of Aluminium field wire (φ= 80μm gold plated Al wire,φ=80,100μm silver plated Al wires) are reported . These wires show long term creeping. There are different reductions of wire tension between several types of Al wire. For comparison the creeping of φ 100μm 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.更多还原
