Abstract
An investigation on an air gap spark chamber under the atmospheric pressure, especially on its efficiency for detecting multiple tracks, is described in this paper. The particle trajectory in a gap is determined within a probable error of 0.5 mm with three spark gaps which are separated from one another by 10 cm. The maximum efficiency for detecting a single track obtained in this study is about 95%. The spurious sparks which are induced by the other spark are prevented by means of isolating optically each gap from others.
