提出了一种提高大型线室定位精度的方法。雪崩的定位只需在平行于线室阳极线的狭窄阴极条上印刷一系列双楔子即可获得。这种方法似乎非常适合作为“游标”技术：粗略方法提供楔形分段的地址，然后以更高的精度给出分段内的位置。
A method is proposed to improve position accuracy in large wire chambers. A localization of an avalanche is obtained simply by printing a series of double wedges on a narrow cathode strip parallel to the anode wire of a wire chamber. This method seems to be well adapted as a “vernier” technique: a gross method provides the address of a wedge subsection which then gives, with a greater accuracy, the position within the subsection.
