新建造了一个时间投影室，用于研究气体样品的核光分解反应。来自反应各个通道的所有带电片段可以通过时间投影室同时检测，在 4π 几何形状中效率约为 100%。使用每个片段的路径长度、脉冲高度、轨道宽度和反应运动学，明确地将这些片段分配给单独的反应通道。利用241Amα源和脉冲激光-康普顿背散射光子束诱导的4He光解体反应，研究了时间投影室的性能。
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 4π. 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 α-source of241Am and the photodisintegration reaction of4He induced by the pulsed laser-Compton backscattered photon beam.
