摘要：

A time projection chamber has been newly constructed for studying the nuclear photodisintegration reaction of a gas sample. All charged fragments from various channels of the reaction can be detected simultaneously by means of the time projection chamber with about 100% efficiency in the geometry of 4 pi. The assignment of these fragments to an individual reaction channel is unambiguously made using a path length, a pulse height, a track width and reaction kinematics of each of these fragments. The performance of the time projection chamber has been studied using the alpha-source of Am-241 and the photodisintegration reaction of He-4 induced by the pulsed laser-Compton backscattered photon beam.
