Track

Japanese: 飛跡 - ひせき(英語表記)track
Track
A visible trace made along the path of a high-speed charged particle through a material. In a cloud chamber, the charged particle produces ions that act as nuclei to produce a train of fog droplets; in a bubble chamber, a train of bubbles is produced. In a spark chamber, the ions act as triggers to produce a train of light spots from the discharge. In a nuclear emulsion, charged particles excite silver halide, which after development produces a train of silver particles. In solids other than metals, highly ionizing charged particles disrupt the atomic arrangement, and when the solid is etched with an appropriate chemical, holes are produced. These devices are called track detectors. The type and energy of the particle can be determined from the shape, length, number of ions per unit length, curvature of the track in a magnetic field, and minute bending of the track due to scattering.

物質中を高速の荷電粒子が通った経路に沿って生じた眼に見える痕跡。霧箱内では荷電粒子がつくるイオンを核として霧滴の列を生じ,泡箱内では同様に気泡の列を生じる。スパークチェンバーではイオンが引き金の役目をして放電の光点の列となる。原子核乾板では荷電粒子はハロゲン化銀を励起し,現像後に銀粒子の列となる。金属以外の固体中で,電離作用の大きい荷電粒子はその原子配列を乱し,適当な薬品で腐食させると孔を生じる。これらの装置は飛跡検出器と呼ばれる。飛跡の形,長さ,単位長さあたりのイオン数,磁場中の飛跡の曲率,および散乱による飛跡の微小な曲りなどから,粒子の種類,エネルギーを知ることができる。
